Findings from Sadat Associates 2004
Embedded Files
In 2003 and 2004, Sadat Associates conducted environmental due diligence on behalf of a prospective purchaser. The investigation included test pits, soil borings, groundwater monitoring, and landfill gas testing to assess site conditions and support redevelopment planning.
The investigation documented groundwater contamination, landfill gas generation, and the absence of engineered systems to manage landfill gas and leachate.

Groundwater & Leachate
Historical groundwater monitoring data showed benzene and chlorobenzene exceedances dating back to the 1980s.

Sadat reported that groundwater conditions were consistent with landfill leachate and that the landfill did not have an engineered leachate control system.

Sadat reported that the site's groundwater monitoring wells had not been sampled since 1990.

Landfill Gas
Landfill gas testing found methane throughout the site and that the landfill did not have engineered gas management controls.

The report identified inconsistencies between historic landfill gas surveys and its own findings. Sadat suggested existing monitoring wells may have been improperly installed or malfunctioning, potentially explaining why landfill gas was not detected during earlier monitoring.
