WESTPORT–Compo Beach will remain closed to swimming until late Tuesday afternoon or Wednesday morning as health officials await results of tests on water samples taken today to determine whether the bacteria level has returned to a safe range.

Health officials closed the beach Friday when one of two weekly samples taken at the beach came back with levels of enterococcus bacteria exceeding health and safety thresholds. The sample showed 190 units of the bacteria per 100 milliliters of water, higher than the threshold of 104 units, said Luci Bango, director of health for the Aspetuck Health District, which includes the beach.

The 29-acre park is open for activities other than swimming. Old Mill Beach and Burying Hill Beach remain open for swimming. 

Enterococcus

Enterococcus is a genus of bacteria used as an indicator by health officials. Its presence signals the possibility that “a whole host of other pathogens could be in the water,” many of them harmful, said Peter Linderoth, director of healthy water and lands with the environmental organization Save the Sound.

Linderoth described the water quality at Compo Beach as “quite good” in general, noting that Save the Sound’s annual Beach Report has given the beach A and B grades for water quality in recent years. Compo Beach’s rating was B- last year, following a B+ in 2023.

Good grades

“Compo Beach has a string of good grades,” Linderoth said. “It’s not totally uncommon to receive an exceeding sample even at a good beach from time to time.”

Water at locations throughout the state, including Compo Beach, is tested every Monday, and sent to a state laboratory in Rocky Hill, Bango said. Samples typically take days to process, as the state scientists review samples from many points on Long Island Sound as well as lakes, ponds and other bodies of water, she said.

A standing order closes the beach automatically following 1.5 inches of rain because stormwater runoff historically elevates bacteria levels, Bango said. But elevated bacteria levels can result from many causes, including droppings from geese, deer or other wildlife in the area.
