8-30 E coli Results

[Ryan O'Donnell]

The sixth and final monitoring day for the Deerfield River Watershed Association was Wednesday, August 30thth. I've attached the results in pdf and png format for you to forward, share online, or print and post.

Volunteers collected samples throughout the Deerfield River watershed and its tributaries that were tested for E. coli bacteria. E. coli is a bacteria found in the guts of all warm- blooded animals, including humans and is used as an indicator to test water for fecal contamination. The EPA recommends against primary contact (fully immersing in the water, i.e. swimming) when there are more than 235 organisms/100 mL water. Bacteria levels are often elevated after heavy rains due to bacteria being carried into nearby rivers by runoff. Because of this, we note whether results are from wet or dry weather sampling events.

Volunteers were out in the heavy rains Wednesday morning collecting these samples and we can see this impact on the high numbers at the tributary sites in particular. Some sites were not sampled due to active lightning in the area. We are now having a dry stretch of weather and would expect numbers to come down into the weekend. Thank you so much to all the volunteers who spent their summer Wednesday mornings collecting samples, rain or shine, during this summer so full of rain! This work would not be possible without them.

Please use these and historic sampling results to help make informed decisions about when and where to recreate more safely. You can also reduce the risk of waterborne illness by avoiding getting water in your mouth, cover any open wounds, and washing hands before eating and drinking after recreating in natural waters.
