Time Critical Removal ActionsBetween 1989 and 1991, three time-critical removal actions were conducted at the Site using a phased approach:
•Phase I: consisted of initial site characterization, segregation of wastes, and packaging of wastes for disposal.
•Phase II: included the transportation and disposal of containerized wastes.
•Phase III: involved excavation and off-site disposal of highly contaminated soils, on-site stockpiling of moderately contaminated soils, decontamination (asbestos) of the main warehouse building, and installation of a ground water interceptor trench and a water treatment system to collect and treat contaminated ground water.
– An off-site air monitoring program was implemented prior to initiation of excavation and continued throughout the active excavation phases for the protection of the local population.12

Time Critical Removal Actions
Beginning in April 1997 there additional removal actions were conducted at the Site.
•April 1997: Removal action to close the interceptor trench and dismantle the associated ground water treatment system. Demolish buildings and dispose of debris in a permitted landfill as “special wastes.”
•December 2002: Removal action for the excavation and off-site disposal of stockpiled contaminated soils at a Subtitle D landfill.
•April 2003: Removal action to complete soil disposal, building demolition, and closure of the interceptor trench.

Extensive Site Characterization• On-site Soil:– VOCs, metals, pesticides, and PCBs present– Pesticides and PCBs do not warrant further action– Arsenic and chromium are metal COPCs
• Surface Water & Sediment: – no constituents of concern
• Indoor Air: – VOCs detected in neighboring residences (36)
• On- and Off-site Ground water: – VOCs detected in ground water. Plume extends 500
feet from site

Bedrock Investigation (On and Off site)
• Ground water flows horizontally through transport zone
• Vertical flow through bedrock limited by low vertical hydraulic conductivities
• Dissolved phase ground water plume appears stable
• Majority of VOC mass resides in rock matrix in upper portion of bedrock
• No recoverable NAPL is present in on-site soil or in ground water atop bedrock

2004 Feasibility Study Remedial Alternatives
Soil Remedial Alternatives•S1 – No Action
•S2 – Off-Site Disposal and Low Temperature Thermal Desorption
– Evaluated three different excavation scenarios based on soil volumes and the duration of treatment.
• S3 – Off-Site Disposal– Evaluated three different excavation scenarios based on soil
volumes and the duration of treatment.
• S – 4 Capping– Involves the construction of a cap over the Site, and does not
call for the removal of contaminated soil.

Ground water Remedial Alternatives• G1 – No Action• G2 – In-Situ Chemical Oxidation– Involves the installation of a chemical delivery system
to promote oxidation of the contaminants in ground water.
• G3 – Pump and Treat– Involves physically extracting the ground water by
using pumping wells and treating the water in an air stripper unit.
• G4 - Monitored Natural Attenuation– No active ground water treatment, but would include
all of the common elements for ground water remediation alternatives in G2 and G3.25
