Poor water quality at Squantz Pond State Park in New Fairfield closed the beach area yesterday.  The state closed water activities at the park after the weekly testing by the Department of Energy and Environmental Protection.  Retesting was done yesterday afternoon, with the results expected to be released today in DEEP’s newest Water Quality Report.  The state tests more than a dozen swim areas for low levels of bacteria that could lead to harmful toxins being formed.  The elevated levels are typically due to rains or run off from nearby land.
