A half-dozen bacteria data collection sites in three New Canaan rivers turned up slightly elevated levels of E. coli following tests that commenced this spring, officials said last week.
The results could indicate nitrogen in the water supply, according to members of the New Canaan Conservation Commission.
“I am not looking at these streams and rivers as drinking water supply, but I am looking at them from a wildlife and biodiversity standpoint and I am trying to get a better feel on, are they getting too much nitrogen in the water?” Commission Chair Chris Schipper said during the appointed body’s Aug. 13 meeting, held via videoconference. “I assume E. coli is also related to nitrogen. And are there other chemicals getting into the water supply?”
The Commission referred to data collection and water quality tests from Harbor Watch, part of Westport-based nonprofit organization Earthplace. The group presented to the Commission last spring. The town approved a total of $25,000 for the professional services in the Commission’s budget for the current fiscal year.
