How Healthy Are Our Rivers?

Westport’s waterways look beautiful.

You just don’t see the bacteria.

Harbor Watch — the Earthplace-based research and education program — has just released a study of water quality in rivers throughout Fairfield County. All 4 of the Westport rivers studied are not as healthy as they look.

Muddy Brook — which discharges into Sherwood Mill Pond — and Pussy Willow Brook, a Mill Pond tributary, exceeded state Department of Energy and Environmental Protection criteria for E. coli.

Sasco Brook failed DEEP criteria for bacteria. So did the Saugatuck River — which, with 2 sewage spills last summer, also showed elevated Enterococci concentrations.

The good news: our rivers are pretty good in terms of dissolved oxygen. That’s an important water quality indicator, because many aquatic species rely on it for survival.

Overall, 77% of the 123 field stations studied by Harbor Watch exceeded either 1 or both of the state criteria for acceptable levels of baceria. Click here for the full report.
