Initially, the purpose of this Phase II ESA was to assess whether the Site has been adversely
impacted in an environmental sense by current and historical activities related to the four RECs
above.
Based on conversations V3 had recently with the Illinois Environmental Protection Agency
(IEPA), additional environmental investigation is being required of Phillips 66 to further evaluate
the extent of impacted groundwater associated with this release. The work will be conducted by
a consultant hired by Phillips 66. Therefore, the Client has requested that V3 not investigate
this REC at this time.
Additionally, V3 was informed by the Client that the Site owner would not allow access to
investigate two other RECs (the hydraulic lifts and the northeast adjacent LUST incident). V3’s
Phase II ESA was therefore limited to investigating the former dry cleaners at the space now
occupied by Mrs. Clean Laundromat (the Laundromat).
OBJECTIVES
The objectives of the Phase II ESA are to assess whether soil and groundwater have been
impacted as a result of reported historical on-site dry cleaning operations.
SCOPE OF SERVICES
The general tasks associated with the Phase II ESA included: site health and safety plan
preparation, private utility location, soil sampling utilizing direct push technology, temporary
monitoring well installation, laboratory chemical analysis of soil and groundwater samples, data
analysis and interpretation, and report preparation. It should be noted that this was not a
comprehensive site investigation designed to delineate potential soil and groundwater impacts.
Field Investigation
Mr. Jeff Paddock, Environmental Geologist with V3, coordinated and provided field oversight of
the work. Paramount Environmental Services of Portage, Indiana, provided drilling services
using a cart-mounted probe inside and a truck-mounted probe outside the Laundromat. Six soil
borings were advanced inside the Laundromat and three soil borings were advanced in the
parking lot directly south of the Laundromat, to a maximum depth of 18.5 feet bgs. Two of the
borings advanced in the parking lot were converted into 1-inch diameter PVC temporary
monitoring wells. Refer to Figure 3 (attached) for sampling locations and Attachment A for soil
boring logs and temporary monitoring well construction details.
Field Procedures
The Laundromat is an active facility. V3 selected soil boring and well locations to sample the
most likely areas expected to be impacted, based on our professional experience in
investigating dry cleaning facilities. Some areas within the Laundromat were not accessible due
to the presence of underground utilities or space limitations. Soil borings in these locations
were advanced with a pneumatic jack hammer, where feasible.
All borings were advanced using direct push sampling equipment and were collected
continuously using new 2-inch diameter, 2 and 4-foot long clear plastic liners. Soil borings SM-
