CRWA’s Volunteer Monthly Monitoring (VMM) program provides data that can be used to better understand the health of the Charles River and its tributaries. In addition to providing the public with an easily-accessible picture of the health of the Charles through EPA's annual Charles River Report Card, the data collected also enable CRWA to identify problem areas so that remediation efforts can be focused more efficiently.
