Since 1995, U.S EPA has used the Charles River Report Card to measure and evaluate progress towards meeting the State of Massachusetts bacterial water quality standards for swimming and boating for the Charles River Watershed. With E. coli data from water samples collected monthly by Charles River Watershed Association (CRWA) volunteers, sound science is used to report on the recreational health of the river, and educate the public on challenges the Charles River faces.
