On October 1st, MyRWA will be joined by Nigel Pickering of the Horsley Witten Group to learn about how a Total Maximum Daily Load (TMDL) was put in place for the Charles River Watershed. A TMDL is a calculation of the maximum amount of a pollutant that a waterbody can receive and still safely meet water quality standards, and may greatly help improve water quality in the Mystic River Watershed. Please attend the Oct. 1st Committee Meeting, Tufts University, Lincoln Filene Center, Rabb Room, Medford. Free and open to the public!
