Bedford officials are calling on Saint-Gobain Performance Plastics to connect properties affected by perfluorooctanoic acid contamination to public water.In 2016, the state Department of Environmental Services requested that Saint-Gobain put in place a public water treatment system for the more than 100 properties affected.Now, the town said wants the company to connect properties to Manchester Water Works immediately, saying people cannot wait until next spring and calling such a delay “unacceptable.”“The residents of these homes have been significantly impacted since they learned of the contamination in April 2016,” wrote the Bedford lawmakers. “Families cannot brush their teeth, rinse food or drink water from the tap in their own homes. Residents had expected to be hooked to municipal water by November 2016. While many homes in southern New Hampshire have been connected to public water, Bedford property owners have not and they have been told to wait for a decision in late September.”PFOA was traced to the Saint-Gobain plant in Merrimack and elevated levels of the chemical have been found in well water in several neighboring towns, including Bedford. The Environmental Protection Agency recently tightened water standards for PFOA, a by-product of making weatherproof or non-stick materials.
