Chemicals found in Glenville groundwater

"I suspect that will a maintenance of long-term monitoring for many years," said O'Neill. "The clean up, the remedial action on the greater neighborhood if you, will depend on what we find further into the investigation and the feasibility."

The goal of the project, said O'Neill, would be to restore the groundwater to the condition before chemicals were released. This would result in a groundwater level of contamination to be less than 5 parts per billion on the chemical.

"We can attack some of the higher concentrations with treatment and then typically we would monitor to make sure [the contamination] is either shrinking or stable over years or periods of time to make sure it is not being a problem and further exposure issue," said O'Neill.

Further off-site investigations from the former Kenco 0.86 acre parcel of land has shown groundwater impacts from the solvent for approximately 0.5 miles southernly from the site. There have been several residential and commercial buildings have been equipped with soil vapor intrusion management systems to mitigate risks and release the vapor below properties.

The data collected by DEC found small areas of significant contamination, with large areas within the plume have lower concentrations of pollution. The chemical containment also doesn't seem to be able to pass through the underground clay layer, which has made the containment form a horseshoe pattern as it has spread.

There have not been any other sources identified for the 0.5 mile downgradient contamination plume at this time. The DEC plans to keep the public updated as the investigation progresses.
