Town of Poughkeepsie Supervisor gives details on changes to Poughkeepsie water and whether or not its safe to drink. Poughkeepsie's drinking water comes from the Hudson River and is treated by the Poughkeepsie Water Treatment Facility to meet all state and federal standards. Poughkeepsie Town Supervisor Rebecca Edwards released a message on the official Town of Poughkeepsie Town Hall Facebook page with detailed information regarding changes to Poughkeepsie water that sometimes happens in September. But anyone who might have direct contact with raw river water (ingestion, inhaling, or skin contact) should exercise caution. It is therefore recommended that residents and pets avoid contact with untreated Hudson River water.
