Town Projects & Water Quality Reports

Towns that are members of the Neponset Stormwater Partnership are regularly working on projects to improve stormwater in their area. Select a project from the list below to learn more.

Towns often pursue the installation of green infrastructure or “Stormwater Best Management Practices (BMPs)” to try and clean up stormwater and improve the health of our local waterways. Installing these mechanisms is essential to solving the issue of stormwater pollution.

Water Quality Reports

Since 1996, the Neponset River Watershed Association (NepRWA) has been collecting water quality data from throughout the Watershed. Samples are collected by volunteers through the Community Water Monitoring Network (CWMN).

Every month (May-Oct.), CWMN volunteers pick up sampling equipment and head to their sites at 6 am to collect water samples.  Some samples are delivered to the lab at the Massachusetts Water Resources Authority (MWRA) where they test for nutrients, primary producers, and E. coli.  Other samples return to NepRWA where we measure pH. Volunteers also measure dissolved oxygen concentration on site.

Several NSP communities conduct regular water testing with the help of volunteers in one or more of their watersheds. In other areas, water quality data may be collected by nonprofit groups or the state Department of Environmental Protection from time to time.

The data is used to assess the health of the Neponset River and tributaries for wildlife and recreation, and to locate pollution sources for follow-up sampling.
