The Southeastern Vermont Watershed Alliance (SeVWA) began its monitoring program for the summer of 2016 on Wednesday, June 22nd. Volunteers will be collecting samples from 30 sites on eight rivers and streams every other week through the end of August. This year, we have sites on the West River, Rock River, North Branch Ball Mountain Brook, Williams River (including South Branch and Middle Branch), Saxtons River, Sacketts Brook, and Whetstone Brook.
Escherichia coli, more commonly known as E. coli, is a bacterium that is found in the guts of all warm blooded animals, including humans. Most E. coli will not make a person sick, but sometimes they can become pathogenic which means they can cause illness. Additionally, the presence of E. coli in waters acts as an indicator for the presence of other, more difficult to test for pathogens. We publish our results to the public in order to help everyone make informed decisions about recreating in Vermont’s waters.
The days leading up to June 22 were quite dry and only a few sites tested above the “suitability for swimming” standard set by the State of Vermont and the US Environmental Protection Agency. Often, high bacteria levels are a result of heavy rains and the day before we tested was generally pretty dry with only some scattered sprinkles. Because heavy rains can cause spikes in bacteria, it is generally recommended to wait 24-48 hours after a significant rainfall to resume swimming in lakes and streams.
SeVWA’s water quality monitoring program is supported by SeVWA volunteers, members and donors, including the Londonderry Conservation Commission, Robert Fritz, Inc, Rock River Preservation, Elaine Lambert Living Trust, State of VT Department of Environmental Conservation’s LaRosa Environmental Testing Laboratory, & Connecticut River Watershed Council (CRWC).
E. coli results charts and accompanying commentaries will appear at www.ibrattleboro.com (Nature section) every 2 weeks through the monitoring season.

Thanks again for all you do to support SeVWA’s monitoring program and for your interest.
