OLD/NEW SANITARY LANDFILLS, SFAAP-018
SITE DESCRIPTION
The entire Landfill Area encompasses approximately
42 acres located about one mile west of the NG Area
near the central-western border of SFAAP. However,
only a portion of the 42 acres make up the Old/New
Sanitary Landfills. The landfills employed a trenchtype
operation. Several types of landfills are included
in the Landfill Area: the sanitary landfill (17 acres);
the ash landfill (10 acres, SWMU 19); and the asbestos
landfill (1.1 acres). This Landfill Area began operation
in 1943. Prior to the designation of the New
Sanitary Landfill in 1967, refuse of all types was buried
at a site just south of the new landfill. No records
from the Old Landfill were available. SFAAP no longer
uses the New Sanitary Landfill; currently, waste is
disposed in temporary cells at a separate location
(SFAAP, 1992). Although there was no hazardous
waste placed in either landfill, there is one area reported
to have received containers of a lead compound
east of the landfill, and 2 areas with known asbestos
waste near the Sanitary Landfill.
The Draft RFI report states that the primary concerns
at SFAAP-018 and 019 are the constituents
detected in groundwater(sulfide;cis-1,3-
dichloropropane,ammonia nitrogen) and dioxins/furans
in the shallow soil. Institutional controls have been
implemented (fencing) to control site access.
PROPOSED PLAN
Additional RFI activities will be performed to delineate
the extent of soil contamination. LTM will be
required. An IRA for GW diversion and erosion control
will be implemented. Remedial action activities
will include diversion of groundwater flow around the
landfill and construction of a landfill cap.
