Volunteer Monthly Water Quality Monitoring Project
Once a month, more than seventy volunteers gather at thirty-five sites
along the river to collect water samples, measure depth and temperature,
and record river conditions. The water quality monitoring program is now in its 17th
year, and is one of the oldest and largest volunteer sampling programs in the country. The data collected is used to
identify problems in the river and trends in water quality, and to track
the progress of efforts to clean up the Charles. The U.S. Environmental
Protection Agency continues to use our data to award a grade for the
annual Charles River report card. Our data and analyses also assist
municipalities and environmental agencies and organizations who are
working to minimize stormwater impacts and reduce sewage contamination
in the river.
Monthly water monitoring volunteers are responsible for taking a water sample at an assigned site once a month at 6am; volunteers are trained by CRWA staff and equipment is provided.
