1. INTRODUCTION
Haley & Aldrich has prepared this Remedial Action Plan (RAP) for Rochford Field, located east of
Newhall Street in Hamden, Connecticut (herein referred to as the “subject site”).
1.1 Background
On 10 July 2001, Connecticut Department of Energy and Environmental Protection (CTDEEP),
formerly known as the Connecticut Department of Environmental Protection (CTDEP), issued Order
No. SRD-128 to: the Town of Hamden, South Central Regional Water Authority (RWA), Olin
Corporation (Olin), and the State Board of Education. The Order required the respondents to
investigate and remediate sources of pollution on a “site” which was subsequently divided into three
portions that included both publicly and privately owned properties. The Order was appealed by all
parties and Consent Order SRD-128 was entered on 16 April 2003. The Consent Order requires the
Town of Hamden to investigate, characterize, and remediate Rochford Field, Mill Rock Park, and the
Sewer Pump Station located at the southeast corner of Mill Rock Road and Winchester Avenue. In
addition, the Consent Order requires that CTDEEP and the Town of Hamden, together, will seek funds
from the State of Connecticut for the investigation and remediation of Rochford Field. A copy of the
Consent Order is included in Appendix A.
On behalf of the Town of Hamden, Haley & Aldrich performed a Phase II and III Environmental
Investigation of Rochford Field and Mill Rock Park (Phase II/III) during the summer and fall 2002.
The results of this investigation can be found in our report entitled “Phase II and III Environmental
Investigations, Rochford Field and Mill Rock Park, Hamden, Connecticut”, dated December 2002.
Long-term quarterly groundwater monitoring of wells in Rochford Field and Mill Park began in April
2003. On 8 June 2004, CTDEEP issued a letter indicating that additional investigation of the study
area was required. On 12 July 2004, a Supplemental Phase III Investigation Work Plan for Rochford
Field and Mill Rock Park (Work Plan) was submitted to the CTDEEP for review and approval. On
14 October 2004, CTDEEP conditionally approved the Work Plan. Haley & Aldrich commenced work
on the Supplemental Phase III investigation late October 2004. Results of the Supplemental Phase III
investigation can be found in our report entitled “Supplemental Phase III Data Investigation and
Preliminary Remedial Action Plan Mill Rock Park, Sewer Pump Station, and Rochford Field, Hamden,
Connecticut,” dated 29 April 2005 and in a subsequent Addendum to the report entitled “Supplemental
Phase III Data Investigation Report Addendum, Mill Rock Park, Sewer Pump Station, and Rochford
Field, Hamden, Connecticut,” dated 11 October 2005.
In August 2006, CTDEEP issued a Proposed Remedy Selection Plan and solicited public comment.
After consideration of the public comment, the proposed Remedy Selection Plan was revised and a
“Remedy Selection Plan”, approved by the CTDEEP Commissioner was published in October 2007.
This RAP details the remedial actions that will be conducted at Rochford Field in accordance with
approved CTDEEP remedy. A separate RAP has been prepared for Mill Rock Park and the Sewer
Pump Station.
1.2 Site Description
The subject site includes the publicly owned property known as Rochford Field, located east of Newhall
Street in Hamden, Connecticut (see Figure 1: Project Locus).
1

The 4.84 acre Rochford Field is a large grassy area that occupies the block bordered by Newhall and
Newbury Streets to the west and south, respectively; Winchester Avenue to the east and Mill Rock
Road to the north. A chain link fence surrounds the recreational facility, which includes baseball
fields, dugouts, backstops, and bleachers. A concrete sidewalk surrounds the outer edge of the
property.
Groundwater underlying the subject site was historically classified as “GAA” by CTDEEP; a “GAA”
classification indicates that the water resource is regulated for potential use as a public drinking water
supply. In 2005, CTDEEP reclassified a portion of the property “GB”; a “GB” classification indicates
that the water resource is not intended to be suitable for use as a drinking water supply without prior
treatment. Both the “GAA” and “GB” groundwater classification areas are shown on Figures 2A and
2B. A public water supply system is used to supply potable water to area residences and businesses.
1.3 Overview of Investigations
In 2001, Haley & Aldrich performed a Phase I Environmental Site Assessment (Phase I ESA) of the
Hamden Middle School and surrounding Newhall Street Neighborhood, which included Rochford Field
and Mill Rock Park. The purpose of the Phase I ESA was to evaluate site history, existing observable
conditions, current site use, and current and historic uses of surrounding properties to identify the
potential presence of Recognized Environmental Conditions (RECs). During the Phase I, Haley &
Aldrich identified several RECs and contaminants of concern (COC) for the subject site. These RECs
and COCs are detailed in our April 2002 “Report on ASTM Phase I Environmental Site Assessment
Hamden Middle School and Surrounding Newhall Street Neighborhood, Hamden, Connecticut”
In addition to Haley & Aldrich’s 2001 Phase I ESA, CTDEEP and Metcalf & Eddy (M&E) conducted
environmental evaluations of Rochford Field for the Town of Hamden between 2000 and 2001. The
previous assessments are described in detail in the Haley & Aldrich Phase I ESA report and briefly
summarized below. Locations of the previous explorations are shown on Figures 2A and 2B.
In December 2000, CTDEEP drilled 14 geoprobe explorations in Rochford Field (SS-21
through SS-34) to depths ranging from 4 to 12 ft below grade; temporary microwells (SS-21,
SS-24, SS-27 and SS-30) were installed in four of the explorations. CTDEEP submitted
composite soil samples (0 to 4 ft depth) for chemical analysis for extractable total petroleum
hydrocarbons (ETPH), total lead, arsenic, thallium and mercury, leachable metals (by SPLP)
and semi volatile organic compounds (SVOCs). Groundwater grab samples from microwells
SS-21 and SS-27 were tested for cyanide, volatile organic compounds (VOCs), SVOCs, and
metals.
In January 2001, CTDEEP collected 14 additional shallow (0 to 6 inches) soil samples (RF-21
through RF-34) from the same locations as SS-21 to SS-34 (December 2000).
In March 2001, CTDEEP conducted additional chemical testing of shallow soil samples for
arsenic at locations designated RF-35 to RF-44. CTDEEP also collected shallow soil samples
(0 to 2 inches and 2 to 6 inches depth) from 20 locations (RF-45 to RF-64) for screening using
X-ray Fluorescence (XRF) and laboratory analysis for arsenic (0 to 2 inch depths only).
2

In April 2001, M&E (CTDEEP subcontractor) collected and analyzed 37 surficial (0-0.25 ft)
soil samples from Rochford Field (T-1 to T-37) for analysis for SVOCs and metals and/or
waste disposal characterization parameters (VOCs, ETPH, total and leachable metals, and
polychlorinated biphenyls [PCBs]).
Results of the CTDEEP and M&E explorations found 2.75 ft to 8.5 ft deep fill deposits
containing a mixture of soil, slag, brick, cinders, wood, coal, rubber, cloth, clinkers, concrete
and metal pellets. An “odor” associated with a layer of black sand and cinders were recorded
at SS-26. Chemical testing of fill and soil samples detected ETPH, SVOCs and metals (copper,
nickel, arsenic, mercury, thallium, and lead) at concentrations in excess of Remediation
Standard Regulation (RSR) RDEC and/or GAPMC. Results of the groundwater analyses
detected SVOCs and metals (including beryllium, cadmium, chromium, copper, lead, nickel,
zinc, and mercury) in excess of RSR criteria. Results of the disposal characterization testing
also detected VOCs (chloromethane and methylene chloride), cyanide, and pesticides (4,4’-
DDD, 4,4’-DDE and 4,4’-DDT) below RSR criteria.
In 2002, Haley & Aldrich conducted a subsurface exploration program in Rochford Field including five
test pits (RF HATP1 through RF HATP5), fifteen test borings (RF HA108 through 119, RF HA121,
RF HA123 and RF HA124), and the installation of four monitoring wells (RF HA108MW, RF HA
110-MW, RF HA115-MW and RF HA123-MW). Results of the Haley & Aldrich investigations are
documented in 9 December 2002 reports entitled “Report on Phase II and III Environmental
Investigations, Rochford Field and Mill Rock Park, Hamden, Connecticut” and “Report on Test Pit
Investigations, Hamden Middle School, Rochford Field & Mill Rock Park, Hamden, Connecticut”.
Locations of the Haley & Aldrich explorations are shown on Figure 2. Results of chemical testing of
soils and groundwater are included in Tables Ia, Ib, IIa and IIb, respectively, along with results of
subsequent analyses. Results of the soil analyses detected widespread impacts from petroleum VOCs,
SVOCs, ETPH and metals within the fill material at concentrations in excess of RSR RDEC and
GAPMC. Chlorinated pesticides were detected at concentrations below RSR criteria. The groundwater
analyses detected SVOCs, ETPH, nickel and zinc at concentrations above RSR GWPC; contaminants of
concern were not detected above RSR Surface Water Protection Criteria (SWPC) or Residential
Volatilization Criteria (RVC).
From October 2004 to October 2005, Haley & Aldrich performed supplemental Phase III explorations
and chemical testing to determine the extent of environmental site impacts related to former filling
activities in the study area. This work was performed to further define the degree and extent of
contamination, and to develop a preliminary Remedial Action Plan (RAP) in compliance with paragraph
B.3.c.(1) of Consent Order SRD-128. The supplemental investigations included site screening with
subsurface interface radar, a metal detector and a magnetometer, excavation of four test pits
(RFHATP6 through RFHATP6) and drilling 19 test borings (RF-HA108D, RF-HA201 through RF-
HA212, RF-HA213A though RF-HA213E and RF-HA214; eight of the borings were completed as
monitoring wells (RF-HA-108MWD, RF-HA201-MW, RF-HA202-MW, RF-HA207-MW, RF-HA208-
MW, RF-HA209-MW, RF-HA211-MW and RF-HA-212MW (Figures 2A and 2B). Results of the
radar and magnetometer testing were used to locate the test pits; no evidence of buried drums or large
pieces of metal was detected. Results of the soil analyses detected SVOCs, ETPH, metals (arsenic,
antimony, beryllium, cadmium, chromium, copper, lead, mercury, nickel, selenium, silver, thallium
and zinc), leachable metals (antimony, arsenic, copper, lead and zinc), chlorinated pesticides, and low
3

levels of VOCs; cyanide was detected in one soil/fill sample tested. Impacts were widespread and
detected SVOCs, ETPH and metals at concentrations in excess of RSR RDEC and PMC. Chlorinated
pesticides were detected at concentrations below RSR criteria. The data did not detect significant
impacts to the natural overburden materials beneath the fill deposits.
The Phase II/III site investigations included six rounds of groundwater sampling at four monitoring
wells in Rochford Field. Groundwater samples were submitted to a Connecticut-Certified Laboratory
for testing for ETPH, VOCs, total and leachable metals, SVOCs, PCBs, pesticides, and cyanide.
Analytical results from Phase II/III and Supplemental Phase III groundwater testing are included in
Tables V and VI. The groundwater analyses detected SVOCs, ETPH, nickel and zinc at concentrations
above RSR GWPC; contaminants of concern were not detected above RSR Surface Water Protection
Criteria (SWPC) or Residential Volatilization Criteria (RVC).
On 29 April 2005, Haley & Aldrich issued a report titled “Report on Supplemental Phase III Data
Investigation and Preliminary Remedial Action Plan, Mill Rock Park, Sewer Pump Station, and
Rochford Field, Hamden, Connecticut.” In addition to summarizing the results of the October 2004 to
February 2005 supplemental investigations and chemical testing, the report included a recommended an
engineered cap and reclassifying site groundwater from GAA to GB. In October 2005, Haley &
Aldrich issued an addendum to the April 2005 report. The addendum, which was titled, “Supplemental
Phase III Data Investigation Report Addendum, Mill Rock Park, Sewer Pump Station, and Rochford
Field, Hamden, Connecticut,” included responses and additional information based on comments
provided by CTDEEP in a 12 September 2005 letter. Refer to the 2005 or previous reports for detailed
information on the previous testing, including boring and test pit logs and laboratory data reports.
1.4 Applicable Remediation Standards
The subject site is being regulated under CTDEEP Consent Order No. SRD-128 and as such, site
conditions are required to demonstrate compliance with CTDEEP Remediation Standard Regulation
(RSR) criteria.
The southern portion of Rochford Field is located in a groundwater area classified as "GB" by the
CTDEEP. The area was reclassified from the previous “GAA” classification in 2005. A “GB”
classification indicates that the water resource is not intended to be suitable for use as a drinking water
supply without prior treatment. The northern portion of Rochford Field parcel remains “GAA” water
resources which indicate that the area is regulated for potential future use as a public water supply. A
public water supply system is used to supply potable water to area residences and businesses.
Applicable RSR soil criteria are:
Residential Direct Exposure Criteria (RDEC)
GB Pollutant Mobility Criteria (GBPMC); and,
GAA Pollutant Mobility Criteria (GAPMC).
Applicable RSR criteria for groundwater quality are:
Groundwater Protection Criteria (GWPC);
Surface Water Protection Criteria (SWPC); and,
4

Residential Volatilization Criteria (RVC).

2. CONCEPTUAL SITE MODEL
2.1 General Description of Study Area
2.1.1 Geology/Fill
The study area is primarily a former wetland that was filled during the early to mid 1900s with
a mixture of domestic and industrial waste materials mixed with soil. The extent of the former
wetland area, and pathway of a former stream that flowed northwesterly from south of Mill
Rock Park and across the central portion of Rochford Field towards Newhall Street, are shown
on a 1934 aerial photograph in the Phase I ESA. The fill materials encountered in the borings
were generally defined as follows:
Site fill materials and natural deposits were generally defined as follows:
Earthen Fill: Soil fill, including topsoil which typically does not contain man-made
artifacts but at some locations may contain variable amounts of root matter, cobbles,
boulders and construction/demolition debris such as concrete, asphalt and brick.
Domestic Refuse Fill: Soil intermixed with products associated with household and/or
on-site burning of paper/wood/coal (ash/cinders), intermixed with rusted metal cans and
numerous whole bottles and broken glass, various broken ceramic items and brick.
Industrial Waste Fill: Black silt and sand sized particles of slag, with cinders and ash
intermixed primarily with wood box fragments, sawdust and/or wood chips, batteries,
scrap metal gun parts, shell casings and furnace bricks.
Miscellaneous Fill: Earthen Fill and/or Domestic Refuse Fill mixed with variable
amounts of Industrial Waste Fill
Based on the results of the Phase II/III field explorations, Rochford Field is generally underlain
by approximately 1 to 3 ft of earthen fill, which is underlain by 0.5 to 7 ft of heterogeneous fill
deposits, including slag-rich “industrial waste fill” interlaid with “miscellaneous fill.” The
industrial waste fill layer typically contained layers of slag, ash, cinders, wood, box fragments,
sawdust, scrap metal gun products with some demolition debris (concrete and brick), furnace
brick, copper fragments, and batteries. The miscellaneous fill layer typically contained
industrial waste fill mixed with organic material and demolition debris such as; sand, wood,
fabric, paper, glass, cinders and cardboard. Generally, the industrial waste fill was
encountered above the miscellaneous material, although industrial waste fill only was
encountered in explorations in the northwest and southeast portions of the site. The
miscellaneous fill encountered in Rochford Field did not contain domestic refuse. Domestic
refuse fill was identified in explorations on the western portion of the site, across from Mill
Rock Park and may represent the western extent of the domestic refuse fill, an area where
domestic refuse fill was dumped along the dirt roadway that predated Winchester Avenue
during the 1920s. Earthen fill was encountered above the industrial waste or domestic refuse
fill at Rochford Field; the thickness of the earthen fill varies from several inches to several feet.
6

Fill was encountered beneath the entire site and adjacent parcels, including Mill Rock Park, the
Sewer Pump Station (addressed in a separate RAP) and the former Hamden Middle School. At
Rochford Field, the thickest fill deposits were encountered in a northwest-southeast trending
zone roughly similar to the path of the former stream observed in the historic aerial
photographs. Fill appears to pinch out to the north towards Mill Rock Road. Fill was
encountered in borings along the Newhall Street right of way. Fill from Rochford appears to
extend southerly and may be contiguous with the fill encountered by others in the block south
of Newbury Street. Additionally, although explorations could not be located in the center of
Winchester Avenue, due to the presence of utilities, based on comparisons of fill thicknesses on
either side of the street; it appears that the fill deposited on Rochford Field is contiguous with
that deposited in Mill Rock Park.
Natural overburden sediments underlying the fill consist of organic material and stream
(alluvial) sediments overlying glaciodeltaic deposits composed of interbedded layers of
primarily silt and sand sized particles. Regionally, the glaciodeltaic sediments have been
mapped as thick (up to 300 ft thick in the site vicinity) glacial Lake Connecticut deposits that
extend from Lake Whitney to Long Island Sound. The deposits reportedly pinch out to the east
(Prospect Hill) and north (Mill Rock). The glaciodeltaic deposits encountered in Rochford
Field explorations appeared to decrease in thickness towards the east.
Alluvial and former wetland sediments were encountered above the glaciodeltaic deposits and
ranged in thickness from 1.5 to 8 ft. The former wetland and stream sediments reflect the
nature of the site prior to filling. Thicker alluvial sediments generally reflect areas where fill
was deposited in wetlands or standing water bodies.
Refer to Appendix B for geologic cross-sections of the study area
2.1.2 Hydrogeology
In 2005, CTDEEP reclassified groundwater beneath the southern portion of Rochford Field as
“GB”, indicating that the resource is not intended for use as a public water supply without prior
treatment. Groundwater in abutting areas to the west and southwest of the site had historically
been classified as “GB.” Groundwater in the northern portion of Rochford Field remains a
“GAA” resource (see Figure 2A). Private or public wells have not been identified in the site
area. The majority of the shallow groundwater beneath the site is generally flowing in a
westerly/southwesterly direction. Groundwater flow beneath Rochford Field is primarily to the
southwest, towards the Hamden Community Center. Flow beneath the northwestern corner of
the field, however, appears to be northwesterly, towards a surface water stream on the west
side of Newhall Street (Figure 2B).
Haley & Aldrich encountered groundwater at depths ranging from 7 to 10 ft below grade in
Rochford Field. Groundwater elevations encountered during the supplemental Phase III
investigation were noted to be slightly higher than those detected in the Phase II/III
explorations, likely reflecting seasonal variations in water levels. The water table in the
northern and southern portions of Rochford Field was generally found at the top of the natural
alluvial or glaciodeltaic sediments. The water table in the central portion of Rochford Field
was encountered within the fill deposits; this area marks the location of former standing water
bodies and a stream, filled in the 1920s and 1930s. Based on an evaluation of the shallow
7

groundwater flow patterns and observations from the exploration program, significant impacts
to groundwater flow from on-site or adjacent utilities were not observed.
Groundwater elevations were based on two sets of measurements performed by Haley &
Aldrich and others in November 2004 and February 2005. Piezometric contours are shown on
Figure 2B and were previously included in the 2005 Supplemental Phase III report.
The location of subsurface utilities in and immediately adjacent to the subject site is shown in
Figure 2B. Based on an evaluation of the flow patterns and observations from the exploration
program, significant impacts to groundwater flow from on-site or adjacent utilities were not
observed.
2.1.3 History
For a more detailed description of the history of Rochford Field, please refer to the Phase I
ESA. The following is a brief summary:
Based on a review of aerial photographs, historic maps and Town of Hamden Annual Reports,
the former wetland area east of Newhall Street, south of Mill Rock Road and north of Newbury
Street (now Rochford Field) was used as a “dump” in the 1920s and early 1930s. According to
information on file in the Hamden Tax Assessors office and information in the 1936 Hamden
Annual Report, the Town of Hamden acquired the property from John M. Morse and Dorothy
H. Morse Struck on 28 September 1936. According to interviews with former residents, much
of the area between Morse Street and Mill Rock Road, west of Winchester Avenue and east of
Newhall Street was used as an industrial landfill and depository for “coke fill” (charcoal
residue and ash).
In late 1936 and 1937, the area was graded, topped with approximately 6 inches of loam and
turned into a recreation field. A ¼-mile long cinder running track was constructed on the field
in 1938. Rochford Field was officially dedicated on 7 June 1939. In the 1940s, a field house
and fence were added.
In 1989, the tornado that passed through Hamden caused a significant amount of damage in
Rochford Field. Apparently, trees were uprooted exposing ash and cinder fill as well as other
solid waste materials.
The Town contracted for the renovation of Rochford Field in 1992. Haley & Aldrich reviewed
a memorandum to the Contractor hired by the Town that cautioned against mixing “cinders and
furnace slag material” when stripping topsoil from the field. According to the memorandum,
the materials had been used as a running surface for “an old running track that looped the
fields”.
In April 2001, CTDEEP and Town officials temporarily closed Rochford Field based on results
of environmental testing in 2000 and 2001 which detected metals and SVOCs in shallow soils
above RSR criteria. In July 2001, M&E monitored interim remedial actions, including the
placement of asphalt pavement or concrete on several unvegetated, high traffic areas at
Rochford Field. The areas that were paved included: locations near the entrance gate, around
the dugout areas, under the bleachers and adjacent to the water fountain. M&E reportedly
encountered “old batteries” during remedial efforts for the southern dugout area. M&E also
supervised the placement of sod in the area of sprinkler lines and the placement of grass seed in
8

the vicinity of sprinkler system manifolds and along the fence line. The objective of the M&E
work was to minimize potential exposure to arsenic-containing soils in high traffic areas.
Following the M&E interim remedial measures, the Town reopened Rochford Field for public
use.
2.1.4 Nature and Extent of Soil and Groundwater Impacts
The Rochford Park fill deposits appeared to increase in thickness to the southeast and
northwest; generally following the path of the former stream observed in the 1934 aerial
photograph of the area. The greatest thicknesses of this material, 11 ft, was observed in RF-
HA209-MW, in the central portion of the field. The thickness of earthen fill covering the
industrial waste fill and miscellaneous fill is shown on Figure 4 in Appendix B. The combined
fill thickness is shown on Figure 5 in Appendix B.
In Rochford Field, fill materials were encountered above alluvial deposits and/or glaciodeltaic
sediments. Alluvial deposits, generally marking the location of former wetlands or standing
water bodies, ranged in thickness from 1.5 to 8 ft. Bedrock outcrops were not observed on the
site, and bedrock was not encountered during the explorations. Based on results of
explorations, conducted by others on adjacent properties, sedimentary bedrock likely underlies
glaciodeltaic deposits at approximately 50 ft below grade. Refer to Figure 3 in Appendix B for
subsurface profiles of Rochford Field.
Groundwater was encountered at or near the top of the natural overburden deposits in the
northern and southern portions of Rochford Field. Within the central portion of the field,
however, groundwater was encountered within the fill material. Refer to Figure 2B for
groundwater elevation information.
Due to the heterogeneous nature of the fill deposits, chemical testing detected various
polyaromatic hydrocarbons (PAHS), ETPH, and metals at concentrations in excess of PMC
and/or RDEC at widespread locations and depths within the fill. Results of chemical testing did
not detect evidence of significant impacts to natural overburden materials underlying the fill in
Rochford Field. Three out of 31 samples of natural overburden materials tested contained one
or more COCs at a concentration in excess of RSR RDEC. Lead and arsenic were detected
above the RSR RDEC in one alluvial sample; ETPH was detected above RDEC in another
alluvial sample; thallium was detected above RSR RDEC in a sample of glaciodeltaic sand.
Chemical testing of soil and groundwater explorations located in the northern portion of
Rochford Field detected elevated concentrations of petroleum hydrocarbons (ETPH) as well as
aromatic VOCs and SVOCs. Results of the geophysical survey did not indicate the presence of
drums.During the drilling of borings RF-HA108-MW, Haley & Aldrich encountered an oily
sheen and/or petroleum odors in samples collected from 5 to 7 ft and 7 to 9 ft below grade. A
similar odor and sheen was observed below the water table (approximately 6 ft below grade) in
RF-HATP-7. RF-HATP-7 was also observed to contain numerous, thin, cut pieces of sheet
metal and other metal objects immediately above and intersecting the water table. Bulk disposal
of scrap metal, which is typically oily or mixed with cutting oils, could have caused elevated
metal impacts associated with a dissolved hydrocarbon groundwater plume. Oil draining from
the metal would have also adsorbed to fine grained material within and underlying the fill. The
9

presence of the oil scrap metal corresponds to the location of explorations with highest
concentrations of SVOCs, aromatic VOCs (RF-HAB108-MW, RF-HA110-MW, RF-HA119,
RF-HA207-MW and RF-HA208-MW) as well as those with the most significant groundwater
impacts (RF-HAB108-MW).
Chlorinated pesticides were detected in shallow soil samples from a number of shallow test
borings at Rochford Field at concentrations below RSR criteria. The samples containing the
pesticide compounds were collected from depths of less than 2 ft below grade, generally within
earthen fill material or in shallow samples of industrial or miscellaneous fill immediately
underlying impacted earthen fill samples. The pesticides are likely the result of historic
maintenance of the field or were present when the material was originally brought to the site
and do not appear to be associated with the industrial waste, miscellaneous or domestic refuse
fill material.
Results of groundwater monitoring have detected compounds similar to those found in the fill
materials (Tables IIa and IIb). Considering the widespread and elevated concentrations of
SVOCs in the fill deposits, minimal detections of SVOCs have been noted in groundwater and
those detections have been limited to two wells (RF-HA108-MW and RF-HA123-MW).
Aromatic VOCs have been detected in some groundwater samples from the northern and
northwestern portion of the site but concentrations have not exceeded applicable RSR criteria.
Concentrations of arsenic, lead, copper, mercury, thallium and zinc have also been detected in
excess of RSR criteria at one or more sampling locations and sampling events. The source of
the groundwater impacts is likely the industrial and miscellaneous fill deposits, including slag,
cinders and scrap metal, encountered throughout the Rochford Field parcel.

3. REMEDIAL ALTERNATIVE ASSESSMENT AND REMEDIAL ACTION PLAN
3.1 Regulatory Compliance
In accordance with the Consent Order, Haley & Aldrich considered remedial options and alternatives to
address soil and groundwater contamination at the subject site. Properties subject to a Consent Order,
such as the subject site, are subject to the CTDEEP RSRs. Several RSR criteria are applicable to the
site due to the presence of both GAA and GB groundwater resources. CTDEEP criteria applicable to
the site soil includes; RSR RDEC, GAPMC, and GBPMC. CTDEEP RSR GWPC, SWPC, and
Residential Volatilization Criteria (RVC) are also applicable to the site groundwater. During the Phase
III and Supplemental Phase III investigations, Haley & Aldrich compared site soil and groundwater
quality to applicable RSR criteria. Results of the site characterization detected soil containing SVOCs,
ETPH and/or metals in excess of RDEC at depths ranging from less than 2 ft. to below the water table.
Soils above the water table also exceeded applicable PMC at widespread locations. Groundwater
beneath Rochford Field contained SVOCs, ETPH, nickel, and zinc at concentrations above RSR
GWPC.
Given the widespread nature and extent of impacts that exceed RSR criteria encountered on the site,
remedial action will be required to achieve RSR compliance at the site. The RDEC is applicable to
soils at depths up to 15 ft below grade. The RSRs allow for use of deed restrictions (known as
Environmental Land Use Restrictions, or ELURs) to reduce the potential for future human direct
exposure to environmentally-impacted materials. ELURs not only record the location of
environmentally impacted materials exceeding RSR criteria, but also require placement of 2 to 4 ft of
clean fill material over environmentally-impacted material exceeding RSR Direct Exposure Criteria
(DEC). The CTDEEP requires the ELUR and the clean fill in order to render environmentallyimpacted
materials “inaccessible”.
In addition, environmentally-impacted material located above the water table that exceeds the RSR
PMC has the potential to pollute groundwater at and down-gradient from the site. Environmentallyimpacted
material that exceeds the RSR PMC will either require excavation and off-site disposal, or an
engineered control (i.e., a cap designed in accordance with the RSRs). An engineered control would be
used in order to make the material “environmentally isolated”. The RSRs allow for several other
options to address PMC impacts including a variance due to the presence of “Widespread Polluted Fill”
and determination of alternative PMC. Widespread Polluted Fill is defined in the RSRs as fill that is:
not polluted with volatile organic substances; does not affect the quality of an existing or potential
public or private water supply; additionally, the placement of the fill was not prohibited by law at the
time of placement and the fill was not placed by the party requesting the variance. The evaluation of
remedial options included the consideration of variances and ELURs as allowed for by the RSRs.
3.2 Initial Screening and Remedial Feasibity Assessment
As part of the Preliminary Remedial Action Plan, Haley & Aldrich considered a variety of potential
remedial technologies and strategies, associated costs, and schedule. A number of remedial alternatives
were eliminated during our initial screening due to their expense, ineffectiveness in treating metalimpacted
soils, potential for direct exposure to neighborhood residents, or limitations due to the volume
and nature of fill at the site. Potential alternatives eliminated during initial screening included:
11

On-site soil washing
Bioremediation or land farming
On-site or off-site thermal desorption or incineration
In-situ solidification or stabilization.
The remedial “Alternatives” which were considered as part of the RAP evaluation included:
Alternative 1 – Complete excavation of all fill material on site that exceeds regulatory criteria:
All material that exceeds RDEC and/or PMC would be excavated to an average depth of
approximately 8 ft. and either temporarily stockpiled on site or loaded directly into trucks for
transportation for off-site disposal (permitted landfill or other no-cost disposal alternative
approved by CTDEEP.) In addition to the average thickness of 2 ft of earthen fill, we assume
that an average contaminated fill thickness of 6.0 ft at Rochford Field exceeds RDEC and
PMC. The contaminated fill must be disposed of at a permitted landfill. Clean fill would need
to be imported to the site to offset the volume of material being disposed of offsite.
Groundwater would be addressed via natural attenuation groundwater monitoring.
Alternative 2 – Excavation of upper 4 ft of fill material: This option would be used in order to
render remaining soil (below a depth of 4 ft) that exceeds the RDEC inaccessible, would use
variances or alternative criteria to address soil exceeding PMC. All material to a depth of 4 ft
would be excavated and either temporarily stockpiled on site or loaded directly into trucks for
transportation for off-site disposal (permitted landfill or other no-cost disposal alternative
approved by CTDEEP.) In addition to the average thickness of 2 ft of earthen fill, it was
assumed that the remainder of the contaminated fill to the depth of 4 ft also exceeds the RDEC.
Clean fill would need to be imported to the site to offset the volume of material being disposed
of offsite. Upon completion of the work, an ELUR would be recorded on the land records.
Groundwater would be addressed via natural attenuation groundwater monitoring.
Alternative 3 – Excavation of upper 2 ft of fill material and installation of an asphalt cap: This
option would be used in order to render remaining soil (below a depth of 2 ft) that exceeds the
RDEC inaccessible, would use variances or alternative criteria to address soil exceeding PMC.
All material to a depth of 2 ft would be excavated and either temporarily stockpiled on site or
loaded directly into trucks for transportation for off-site landfill disposal and or recycling. It
was assumed that all fill to a depth of 2 ft exceeds the RDEC. Clean fill would need to be
imported to the site to offset the volume of material being disposed of off-site. The clean fill
and a 6 in. layer of processed aggregate would be covered with a minimum 3 in. thick paved
surface. The paved surface would also require the installation of storm drains, and potentially
additional storm water management facilities, to control the additional surface water runoff.
Upon completion of the work, an ELUR would be recorded on the land records. Groundwater
would be addressed via natural attenuation groundwater monitoring.
Alternative 4 – Installation of a 2 ft thick engineered cap placed on the ground surface and
designed in accordance with the RSRs: The RSRs allow placement and maintenance of a
CTDEEP-approved engineered control as a means to achieve RSR compliance. The engineered
control would consist of an impermeable HDPE membrane and drainage system to be installed
over the contaminated soil. The membrane would be underlain by a 6 in. “cushion” layer of
imported sand or screened earthen fill, and covered by a 12 in. layer of imported sand. The
12

surface would be restored with a 6 in. layer of topsoil and hydroseed or processed aggregate
and pavement. The installation of the engineered control may also require upgrades or
additions to existing storm water management facilities to control the additional surface water
runoff and could potentially require a grade raise to facilitate construction. This option would
include long term maintenance and monitoring of the engineered control and an ELUR would
be recorded on the land records. Groundwater would be addressed via natural attenuation
groundwater monitoring.
All of the recommended options included reclassification of groundwater. In 2005, CTDEEP approved
the reclassification of groundwater in the southern portion of the site from “GAA” to “GB” (see
Figures 2A and 2B). Haley & Aldrich also evaluated various options for disposal or recycling of fill or
other materials excavated from the site, associated with the alternatives considered:
off-site landfill disposal and/or recycling; and,
using the Hamden Middle School site (or other no-cost disposal alternative) for disposal of
waste materials.
Based on experience with similar projects, We believe that it will take approximately one year to design
the selected remedial alternative, obtain regulatory approvals and bid/select contractor(s). During this
period, all required permits and authorizations (such as construction and remedial dewatering general
permits, and landfill disruption authorization, if required) could be obtained. The duration of
construction activities varied from 2 to 6 months for the Alternatives considered. Refer to Table X in
Appendix C for a more detailed breakdown of the information evaluated.
3.3 Recommended Remedial Alternative
Based on the remedial feasibility study, Haley & Aldrich concluded:
Alternative 4 above was the best option because the other alternatives provided less protection
for area residents Alternative 4 minimizes potential exposure pathways associated with
disturbance of the fill materials. The other alternatives would have required significant
excavation of contaminated soils and transportation of this material through the neighborhood.
Furthermore.
Alternative 4 allows for a continuation of the existing recreational uses (i.e., ball fields and play
areas) that are significant to maintaining the character and quality of the neighborhood.
Due to the widespread, extensive areas where PAHs, ETPH and metals exceed RSR DEC and
PMC, an engineered control (such as cap designed in accordance with RSRs) is the
recommended method to protect human health and the environment.
In addition to the engineered control, an ELUR should be recorded for the property to
document the location of site contaminated soils and prevent future disturbance of fill materials
beneath the engineered control without appropriate protective or remedial measures.
In order to achieve groundwater compliance with RSRs, Haley & Aldrich recommended natural
attenuation groundwater monitoring.
13

3.4 CTDEEP Selected Remedy
In 2005, CTDEEP reclassified the southern portion of Rochford Field from “GAA” to “GB”; the
northern portion of the site remains a “GAA” water resource.
In 2007, CTDEEP published a “Remedy Selection Plan” for the Newhall Neighborhood, including
Rochford Field. As part of the 2007 “Remedy Selection”, CTDEEP approved Alternative 4 (outlined
in Section 3.2, above), which requires installation of an engineered control as the remedial strategy for
Rochford Field. CTDEEP stated that remedy provides the best protection for area residents while
alleviating the environmental impacts from the historic fill. This alternative is protective of human
health, safety, welfare and environmental concerns and minimizes potential exposure pathways
associated with disturbance of the fill materials. Furthermore, this alternative allows for a continuation
of the existing recreational uses (i.e., ballfields and play areas) that are significant to maintaining the
character and quality of the neighborhood. Such a remedy clearly is consistent with the existing and
future use while not unnecessarily increasing the costs to the Town’s taxpayers and exposure risks to
the neighboring residential property owners.
In order to implement the CTDEEP selected remedy, the following work will be required:
.
Demolition of the existing ball field facility including the removal or in-place abandonment of
existing utilities.
Installation or perimeter retaining wall and grading ground surface for proper drainage.
Cleaning of existing stormwater sewage system between the site and the point of discharge.
Installation of the impermeable barrier, drainage pipes and backfill materials.
Replacement of utilities (such as sprinkler system, electrical and water), topsoil, trees, and sod.
Replacement of ball field equipment and perimeter fence.
Application of an ELUR.

4. SOIL REMEDY
4.1 Overview
In accordance with Alternative 4 outlined in Section 3, proposed remedial measures to be used at
Rochford Field include construction of an engineered control (EC), placement of an ELUR to restrict
access to soil below the EC, and natural attenuation groundwater monitoring. The following sections
address the remedial strategies will be used to bring Rochford Field into compliance with the RSRs.
An overview of the proposed site design for Rochford Field is shown in Figure 3. The site design
includes baseball and little league fields, landscaped areas and an entrance gate. A detailed profile view
is shown on Figure 4. Plan notes and details are shown on Figure 5.
4.2 Engineered Control Design and Construction
Section 22a-133k-2(f)(2) of the RSRs permits the use of an engineered control (EC) to physically isolate
polluted soil from direct exposure to humans and/or infiltrating storm water from polluted soil to
protect groundwater quality. CTDEEP published a “Guidance Document, Engineered Controls
pursuant to Section 22a-133k-2(f) of the Connecticut Remediation Standard Regulations” dated
February 2009 and revised November 2010. This guidance document describes an engineered Control
as:
A permanent physical structure designed to safely isolate pollutants which would
otherwise not comply with the self-implementing remedial options allowed in sections
22a-133k-1 through -3 of the Remediation Standard Regulations (RSRs). An EC is a
“variance” which requires the Commissioner’s approval. It generally contains
inspection, maintenance and reporting requirements, the recording of an Environmental
Land Use Restriction (ELUR), and the posting of financial assurance to ensure such
measures will be sustained into the future.
In accordance with 22a-133k-2(f)(2)(A)(iv), CTDEEP requires a variance to construct a direct exposure
EC to prevent direct human contact with polluted soil. In the 2007 Remedy Selection Plan, CTDEEP
has requested, and as such, approved construction of an EC at the subject site.
4.2.1 Overview
The EC will be necessary to address RDEC and PMC compliance through the physical isolation
of polluted soil. The EC will include an impermeable membrane and 2 ft of fill material; the
EC design is shown in Figures 4 and 5 and described in the following section. Generally, the
EC will be constructed with a gravel layer (above the impermeable liner) to facilitate drainage,
graded to promotes runoff, resistant to erosion, and designed to account for settlement. The
EC design will be locally modified to include:
Shallow rooted trees with approximately 90 percent of root mass within two feet of the
ground surface and no tap root (see Figures 4, 5 and 6);
Footings for a retaining wall and sidewalk to be constructed along the perimeter of the
site (see Figures 4 and 5).
15

The depth of the liner and gravel will be varied as needed to account for the excavations for the
trees and footings.
The EC will require similar levels of maintenance as the Town budget presently provides for.
The site will consist primarily of grassy and landscaped areas which will be maintained as
recreational ball fields. The uppermost surface of the EC will be inspected quarterly and
repairs will occur within a reasonable amount of time following discovery of any breaches
which would impair the integrity of the EC.
An ELUR will be placed on the site restricting disturbance of soil beneath the impermeable
liner. The site sprinkler system piping will be located in fill material above the impermeable
membrane. There is no anticipated vapor intrusion pathway, and no enclosed structures will be
constructed on top of the EC. There are no surface water bodies or wetlands located on the site
that would be expected to interfere with the EC.
4.2.2 Engineered Control Design
The EC will be constructed in six layers, as follows:
A 6-inch thick soil cushion, to be placed on or about the existing ground surface/grade
(or at the base of excavations for trees, posts or footings);
A 40 MIL HDPE impermeable membrane (less than 1 x 10-6 cm/sec permeability);
A 6-inch layer of gravel;
A permeable geotextile fabric to protect the gravel layer from siltation;
A 6-inch layer of common fill;
A top layer consisting of either a 6-inch layer of topsoil covered with grass (thicker
topsoil will be used around root balls for trees), or a 6-inch layer that includes 3 inches
of subbase (gravel) and 3 inches of concrete pavement.
Existing subsurface utilities will be abandoned in place prior to beginning construction.
Drainage layer piping will be laid around the perimeter of the site and will discharge into the
existing storm sewer in the northwest corner of the parcel. Because the EC construction
includes raising the grade by 2 ft, a brick retaining wall and fence will be constructed along the
perimeter of the field.
Six of the existing groundwater monitoring wells will be maintained for future monitoring (RF-
HA108-MW, RF-HA108-MWD, RF-HA207-MW, RF-HA123-MW, RF-HA115-MW and RF-
HA110-MW). The wells will be protected during construction, and extended 2 ft to meet the
finish grade. One new groundwater monitoring well (RF-HA301-MW) will be installed in the
southwestern portion of the park. The wells will be completed with flush-mounted, locking
caps. If wells are lost during construction, they will be replaced before the end of construction.
Refer to Figure 2B for well locations.
16

The EC will encompass the entire Rochford Field site (shown in Figure 3). The EC design is
consistent with direct exposure and PMC ECs approved by the CTDEEP at a number of sites in
Connecticut. Section 22a-133k-2(f)(2)(B) of the RSRs requires that ECs be designed and
constructed to meet the following conditions:
1) Function with minimum maintenance: The pavement surface covering portions of the
EC will require similar levels of maintenance as the Town budget presently provides for.
The grassy areas of the EC will be landscaped and maintained by the Town of Hamden.
Maintenance will include cutting and watering the grass and properly winterizing the
drainage system. In addition, periodic inspections of the EC will be conducted as part of
an operation and maintenance (O&M) program to ensure that the control continues to
function.
2) Promote drainage and minimize erosion or other damage to the control: The EC will
be graded, and constructed with a gravel layer on top of the impermeable membrane to
promote drainage and minimize erosion and other damage to the control.
3) Accommodate settling and subsidence of the underling soil so as to maintain the
control’s integrity: Materials placed as part of EC construction will be compacted to
prevent subsidence and settling. The O&M inspection program will include observations
for evidence of significant settling or subsidence. If observed, repairs will be made to
preserve EC integrity.
Following construction, an O&M Plan will be prepared for the Town to use to ensure compliance with
the above noted CTDEEP conditions.
4.2.3 Stormwater Management
Stormwater drainage from the subject site was evaluated by Haley & Aldrich based on a recent
2012 study by others of seven basins within the Newhall Area of Hamden, CT (DTC Inc.,
“Newhall Area Drainage Study, Hamden, Connecticut” March 27 2012). Our evaluation was
conducted using the methodologies presented in the Connecticut Department of Transportation
Drainage Manual. The site is located along the northern edge of a 51-acre basin in the
northeastern corner of the Newhall Neighborhood. Runoff from the site and this drainage basin
discharges from a storm drain outfall located to the north of the former Hamden Middle School.
Site stormwater runoff was estimated by comparison of the site to the 51-acre drainage area.
Runoff estimates were then evaluated using a runoff coefficient selected for the existing site
conditions and runoff coefficient selected for the future condition of the site with an
impermeable barrier. Runoff estimates of both conditions were compared and indicate that the
presence of an impervious cover will not significantly change existing drainage conditions.
Refer to Appendix D for additional details.
Based on the above analysis, the final design will incorporate the following stormwater
management elements:
Prior to installing the impermeable barrier, the existing downgradient stormwater
drainage infrastructure will be inspected, cleaned, and if necessary, repaired.
17

The impermeable barrier will be sloped to drain to a perimeter water collection system.
The perimeter collection system will be connected to the existing stormwater drainage
infrastructure proximate to the subject site.
Refer to Figures 3A and 5 for additional drainage details.
4.3 Monitoring Effectiveness of Remedial Approach over Time
4.3.1 Plan & Schedule for Inspection
Quarterly inspections of the EC will be conducted by the Town to confirm damage to the EC
has not occurred. During inspections, the site will be walked such that all areas of the EC are
directly observed. Inspection will include visual observation to confirm that there are no
breaches which would impair the integrity of the EC.
Repairs to the EC will occur within a reasonable amount of time following discovery of any
breaches which would impair the integrity of the EC. Documentation of the inspections and
repairs will be maintained by the Town of Hamden.
4.3.2 Plan & Schedule for Maintenance
Preventative maintenance activities will include filling seams or cracks and sealing asphalt
surface portions of the EC on a five year basis.
4.3.3 Groundwater Monitoring Plan
Long term groundwater monitoring will be conducted to demonstrate compliance with the RSRs
and confirm the effectiveness of the EC at preventing migration of liquids through the release
area. Details of the long term, natural attenuation monitoring plan are included in Section 5.
4.3.4 Plan & Schedule for Reporting
4.3.5 ELUR
In accordance with Section B.3.1.(2). of the Consent Order, on or before 15 days of completing
remedial actions, the Town of Hamden shall certify to CTDEEP in writing that the remedial
actions have been completed as approved.
For the first five years after installation of the EC, reports documenting inspections, repairs,
and maintenance will be provided to CTDEEP on an annual basis. Subsequent reports will be
provided to CTDEEP every five years.
An ELUR will be filed for the site by the Town of Hamden as part of remediation. The ELUR
will be used to render soils beneath the EC “inaccessible” and “environmentally isolated” and
will include restrictions to prevent activities that could disturb the EC or underlying polluted
soils.
18

4.4 Implementation of Environmental Land-Use Restriction
As indicated in the previous sections, Haley & Aldrich will provide technical assistance to the Town of
Hamden to implement an ELUR on Rochford Field, which will be used to demonstrate RSR compliance
by rendering soils below the EC “inaccessible” and “environmentally isolated.” The ELUR will be
used to demonstrate compliance with RSR criteria and will be protective of human health and the
environment.
4.5 Implementation Schedule and Public Notice
Haley & Aldrich anticipates initiating design during Spring/Summer 2013 and construction activities
during 2014; a start date is tentative at this time. However, the overriding goal is to minimize the
downtime for Rochford Field to one growing season in order to establish grass which is able to
withstand various athletic activities.
Public Notice of future remediation activities will be handled per forthcoming CTDEEP guidance.
19

5. LONG-TERM GROUNDWATER MONITORING PLAN
GWPC and SWPC will be addressed through natural dilution and attenuation monitoring or
demonstration of point of compliance monitoring (i.e., monitoring of groundwater at down gradient
locations prior to groundwater discharge to surface water).
At a minimum, groundwater monitoring will include four quarterly, followed by three annual
groundwater monitoring events. The first planned quarterly monitoring event will take place
approximately two to three months after earthwork activities have been completed. Additionally, one
round of groundwater monitoring will be conducted prior to the start of the remedial construction.
The monitoring well network will include six existing monitoring wells (RF-HA108-MW, RF-HA108-
MWD, RF-HA207-MW, RF-HA123-MW, RF-HA115-MW and RF-HA110-MW) and one new
monitoring well (RF-HA301-MW), shown on Figure 2B. The wells will be protected and extended (2
ft) during EC construction. During each monitoring event, groundwater will be sampled using lowflow
purging and sampling methodology. The samples will be analyzed for constituents that are
consistent with those previously detected in soil and groundwater and include the following:
VOCs via USEPA Method 8260B;
PAHs via USEPA Method 8270C;
ETPH via Connecticut DEP methods;
13 Priority Pollutant Metals (totals, unfiltered) via USEPA Method 200.7/200.8.
The monitoring results will be tabulated and compared against the GWPC, SWPC and RVC.
Following completion of four years of monitoring, the data will be evaluated with regard to the
requirement and frequency of any additional monitoring and to evaluate compliance with GWPC,
SWPC and RVC. We will submit our recommendations for future groundwater monitoring to
CTDEEP for review and approval.
Once CTDEEP determines that groundwater compliance at the site has been achieved, the wells will be
abandoned in-place by filling the wells with cement grout.

1. This table includes only those compounds which were detected.
2. RSR criteria means Remedial Standard Regulation criteria established by the CTDEEP.
3. ND means the compound was not detected above minimum laboratory detection limit.
4. NE means no criteria established by CTDEEP for listed compound.
5. -- Compound not analyzed for or not applicable.
6. ug/kg means micrograms per kilogram; mg/kg means milligrams per kilogram; mg/l means milligram per litre
7. Analytical results as reported above the GAPMC are presented in bold type. Values in a box exceed RDEC.
8. RSR DEC for lead (400 mg/kg) is based on a proposed revision to the current 500 mg/kg DEC for lead.
9. The above 'Soil Type' was described by Haley & Aldrich, Inc. as the following:
EF: Earthen Fill: Soil fill, including topsoil which typically does not contain man-made artifacts but at some
locations may contain variable amounts of root matter, cobbles, boulders and construction/demolition debris
such as concrete, asphalt and brick
DRF: Domestic Refuse Fill: Soil intermixed with products associated with household and/or on-site burning of
paper/wood/coal (ash/cinders), intermixed with rusted metal cans and numerous whole bottles and and brick.
broken glass, various broken ceramic items
IWF: Industrial Waste Fill: Black silt and sand sized particles of slag , with cinders and ash intermixed with wood
fragments, sawdust and/or wood chips, batteries, Winchester-related products, Shell casings & furnace bricks.
MF: Miscellaneous Fill: Earthen Fill and/or Domestic Refuse Fill mixed with variable amounts of Industrial Waste
AD: Alluvial Deposits: Organic rich deposits associated with former intermittent watercourse and wetlands.
GD: Glaciodeltaic Deposits: Glacial meltwater deposits consisting primarily of sand and silt.

Alternative 3 – Excavation to 2 ft Depth and Asphalt Cap
Alternative 3A: On-site excavation to a depth of 2
ft. below grade and off-site landfill disposal or
recycling, replacement of excavated material with
clean fill, placement of an asphalt cap, ELUR,
Alternative PMC or Application for Widespread
Polluted Fill Variance, Groundwater
Reclassification and natural dilution and
attenuation groundwater monitoring.
Alternative 3B: On-site excavation to a depth of 2
ft. below grade and off-site disposal at the Hamden
Middle School site, replacement of excavated
material with clean fill, placement of an asphalt
cap, ELUR, Alternative PMC or Application for

Reclassification and natural dilution and
attenuation groundwater monitoring.
Both Alternatives:
Less expensive than removal of all material exceeding
RDEC and PMC (Alternative 1)
Less expensive than removal of all material to 4 ft.
depth (Alternative 2)
Less soil removal reduces duration of exposure risk to
workers and public during excavation, reduces risk of
releases during transportation, and reduces duration of
noise, air pollution and potential for injury associated
with transportation
Achieves compliance with RDEC and PMC
Reclassification of groundwater would allow soil data to
be compared with less stringent GB PMC
GWPC would not apply
Confirmatory soil sampling not required
Dewatering not required
Most excavated material would be acceptable for
landfill cover
Alternative 3A:
Less risk of exposure to workers and public by
eliminating stockpiling and placement activities at the
Hamden Middle School site
Alternative 3B:
No disposal facility costs
Lower transportation costs for disposal than Alternative
1A
Less transportation-related issues than Alternative 1A
Both Alternatives:
Long-term monitoring required

protection of health and the environment
No off-site soil removal: minimizes risk of releases
during transportation, and reduces duration of noise, air
pollution and potential for injury associated with
transportation
Minimizes duration of exposure risk to workers and
public during construction
Minimal imported materials which reduces costs for
material purchase and transportation and reduces
duration of noise, air pollution, and potential for injury
associated with transportation.
Achieves compliance with RDEC and PMC
GWPC would not apply
Confirmatory and characterization soil sampling not
required
Shortest time to complete
Dewatering not required
Long-term monitoring and maintenance of cap required
Future disruptions must follow ELUR – additional costs to be
born by Town for disturbances
Additional costs related to protection against worker and public
exposure risks in the event cap is disturbed in the future
Cap requires installation of storm drains, additional storm water
management facilities to control additional surface water runoff

Notes
1. Remedial Alternatives assume no remedial work at the Sewer Pump Station.
2. Per CTDEP, Option “B” (i.e., disposal of waste material at the Hamden Middle School site) must be considered as part of the Remedial Alternatives Assessment. However, other no-cost alternatives may be
identified after further evaluation and consideration by all parties involved and affected.
3. GWPC will be addressed by groundwater reclassification and/or natural dilution and attenuation groundwater monitoring. SWPC will be addressed through natural dilution and attenuation monitoring or
demonstration of point of compliance monitoring (i.e., monitoring of groundwater at down gradient locations prior to groundwater discharge to a surface water).
4. Opinions of Probable Costs do not include cost for obtaining CTDEP RSR variances, alternative criteria or ELURs. Opinion of Probable Costs does include cost to restore existing recreational uses (i.e., playground
equipment, ball field equipment, bleachers, etc.)
5. Pursuant to Section B.1.b and c of the Consent Order, the Town of Hamden shall pay for the investigation and remediation of Mill Rock Park and the State of Connecticut is to fund the investigation and remediation
of Rochford Field. However, for the purposes of this remedial alternatives assessment, these costs have been combined.
6. Construction Duration does not include the time required to obtain CTDEP RSR variances, alternative criteria, ELURs or approval of remedial design.
