Gail Heinsohn is reporting in the Chatham Courier results of PFOA tests performed in March at the Dewey Loeffel Superfund site in Nassau are in. While PFOA-related compounds were found in the groundwater, the levels were well below the Environmental Protection Agency’s provisional health advisory minimum, according to a report from Town Supervisor David Fleming. Fleming called for the testing because of the site's history of water contamination and ongoing water quality issues in Hoosick Falls and Petersburgh. The EPA agreed to test both the groundwater and the effluent coming from the Dewey Loeffel water treatment facility, Fleming said. He said it appears filtration at the plant has had an impact on potential contamination. Between 1952 and 1968, an estimated 46,000 tons of toxic industrial waste were dumped at the Dewey Loeffel site. The EPA has verified the waste included industrial solvents, waste oil, PCBs, scrap materials, sludge and solids. Read the full story in the Chatham Courier.
