Leaking containers and discolored soils were noted on the site by NYSDEC in 1984. No spills were reported, but given the nature of historic operations, a Phase I study concluded the quality of subsurface soils and/or groundwater could not be determined without additional subsurface investigation. A Phase II investigation was performed and identified elevated heavy metals nearby the TSD area. The new owner of the facility entered into a VCA to address these impacts. Background conditions were established and boundaries of impacted areas were defined.
The owner entered into a Voluntary Cleanup Agreement (VCA) with NYSDEC to investigate and remediate the site, which currently operates a specialty metals stamping plant. A VCA work plan was submitted to NYSDEC and approved in 2001. Studies included information gathering, soil borings and soil sampling, surface soil sampling in stained soil or former drum storage areas, background soil sampling, shallow groundwater well installation, groundwater sampling, surface water and groundwater level measurement, surface water sampling, sediment sampling, background surface water sampling, AST assessment and a sensitive receptors survey.
A Human Health Exposure Assessment (HHEA) was completed to evaluate potential on-site exposures and the potential for off-site exposure pathways and human health risks associated with Compounds of Concern (COCs). The COCs at the site were inorganic metals in soil, including arsenic, cadmium, chromium, lead and mercury. Primary exposure pathways were determined to be limited to metal-bearing dust inhalation. The area around the site is serviced by a municipal water system, but there is no significant potential for chronic human exposure to water-born site contaminants.
