KILLINGWORTH — The swimming area at Chatfield Hollow State Park has been closed after testing revealed elevated levels of bacteria, officials said.

The water at the swimming area will be re-tested Wednesday with results due back on Thursday, the state Department of Energy and Environmental Protection said. The agency oversees the state’s parks along with its nearly two-dozen swimming areas.

“Indicator bacteria are not disease-causing pathogens but are one of the tools used by public health and environmental protection authorities to evaluate the potential for contamination of waterbodies,” the agency said.

Swimming at the state’s four coastline parks — Hammonasset Beach State Park in Madison, Rocky Neck State Park in Niantic, Sherwood Island State Park in Westport and Silver Sands State Park Milford — remains unaffected.

The swimming area at Mashamoquet Brook State Park in Pomfret remains closed throughout the 2022 season due to maintenance, DEEP said.

Testing at municipal beaches is the responsibility of local health departments. Some towns also elect to close beaches after a certain amount of rainfall, which can lead to a spike in bacteria levels at swimming areas.

The closure in Killingworth comes as another sweltering day is forecast for Connecticut on Tuesday, with high temps and humidity combining to produce temperatures that feel like more than 100 degrees.

A cold front could provide relief as early as Wednesday, bringing with it showers and storms.
