Our Community Water Monitoring Network (CWMN) allows us to collect water samples from across the Neponset Watershed.

The NepRWA CWMN program, begun in 1995, provides us with annual water samples from 41 sites across the Neponset Watershed.

Dependant primarily upon volunteers, the program allows us to pinpoint pollution sources, monitor the success of pollution reduction efforts, and track emerging trends. CWMN is foundational to everything that we do at NepRWA and once we uncover pollution sources, we work with our towns to get them cleaned up. Without question, the success of our water testing program is due to our volunteers!

Please email NepRWA River Restoration Director, Sean McCanty, at mccanty@neponset.org if you have any questions about the CWMN program.

CWMN volunteers take water samples at sites throughout the Neponset River Watershed, assessing the sites and water for:

  • Depth of the water body
  • Rate of water flow
  • Clarity, color, and odor of the water
  • Temperature of the air & water
  • Current and prior weather
  • Dissolved oxygen levels

Water samples are lab tested and monitored for:

  • E.coli
  • Total Phosphorus
  • Total Nitrogen
  • pH
  • Dissolved Oxygen
  • Ammonia
  • Temperature
  • Chlorophyll A
