SeVWA’s 2017 E. coli Monitoring of Local Rivers Continued August 16th

The Southeastern Vermont Watershed Alliance (SeVWA) continued its monitoring program for the summer of 2017 on Wednesday, August 16th. Volunteers this year are collecting samples from 34 sites on nine rivers and streams every other week through the end of August. This year, we have sites on the West River, Flood Brook, North Branch Ball Mountain Brook, Rock River, Williams River (including the Middle Branch), Saxtons River, East Putney Brook, Sacketts Brook, and Whetstone Brook.

The days leading up to August 16th were hot and humid, with the majority of sites experiencing no rainfall in the 24 hours before samples were collected. Most of our sites tested below the “suitability for swimming” standard set by the State of Vermont and the US Environmental Protection Agency. The dry conditions in the 24-48 hours leading up to testing set the stage for safe conditions for swimming and boating. Because heavy rains can cause spikes in bacteria, is generally recommended to wait 24-48 hours after a significant rainfall to resume swimming in lakes and streams.
