As you know, MassDEP has been working with your local responders to investigate a fishkill in the Charles River and Stop Brook. This started last Thursday afternoon. We have had staff from our chemical emergency response program, watershed management, resource protection/drinking water, Dept. of Fish Wildlife , Dept. of Public Health, and US EPA as well as our mobile field lab checking various locations along the observed impact area. All tests have come back negative. We have checked a number of facilities with river discharge permits and found no problems. Bottom line is that we have found no man made causes for this incident. In addition, a similar event happened in Bridgewater and similar circumstances were seen in Lakeville. This all points to a very unusual natural event.
We are keeping on top of this issue. Call if you have any questions (508) 965-6318.
