Kenneth C. Crowe II is reporting for the Times Union the torrential rains that hit the town of Nassau almost two weeks ago caused sediments from the Dewey Loeffel Landfill Superfund site to pour into the Little Thunder Brook and down into the Valatie Kill, raising concerns about the spread of toxic waste from the industrial dumping ground. “Because of the volume of transfer down the streams, this isn’t just a Nassau problem. This is a Capital Region problem,” town Supervisor David Fleming said Mon., Jul. 26y Dewey Loeffel is located on Mead Road in Nassau, one of the roadways shut down by flooding caused by the massive thunderstorms that moved across central and southern Rensselaer County on July 15. “There was a massive amount of sediment from the storm and the subsequent flooding. There were extremely high flood levels down the stream that empties into the Valatie Kill,” Fleming said. The flooding caused sediment to be deposited in nearby fields, front yards and around homes. The U.S Environmental Protection Agency and the state Department of Environmental Conservation went to the dump site after the storm. EPA has conducted sediment testing and is doing water quality tests of the streams through July 30. The agency also is examining the area around Nassau Lake. The heavily polluted Dewey Loeffel Landfill contains an estimated 46,000 tons of industrial waste, including industrial solvents, waste oil, PCBs and more. Little Thunder Creek is a 1,900-foot-long tributary of the Valatie Kill, a protected trout stream that empties into Kinderhook Lake in Columbia County. Residents along the Valatie Kill and in the village of Nassau who have seen sediment deposits on their properties are urged to contact the EPA at 518-407-0400, ext. 4. "EPA will be sharing the results of residential sampling with property owners and will continue to provide updates to the community, ..." said an EPA spokesperson.
