NEW FAIRFIELD—After being closed for a week due to unsafe levels of bacteria, the swimming area at Squantz Pond State Park has been reopened.

An unsafe level of so-called “indicator” bacteria was reported last Friday morning as part of the weekly water-quality test the state performs in 23 state park swim areas, according to the state Department of Energy and Environmental Protection. DEEP spokesman Dennis Schain said the higher levels of bacteria tend to occur when a lot of rain washes materials, such as animal feces, into the water from the shore.

The department re-tested the waters this Thursday and reported the results, and that the pond is open, on Friday.
