Since July 2000, MyRWA has been monitoring trends in water quality with the help of a dedicated corps of volunteers. Water samples are collected from fifteen sites across the watershed and are analyzed for:

  • Bacteria: Enterococcus or E. coli
  • Total suspended solids
  • Nutrients: nitrate-nitrite, total phosphorus
  • Conductivity
  • Dissolved oxygen
  • Water temperature
  • Water color and odor

Baseline data is used as the basis for the annual water quality report card issued by the US Environmental Protection Agency. 


EXPLORE WATER QUALITY RESULTS

MyRWA, together with the US Environmental Protection Agency (EPA), issues a yearly water quality report card for the Mystic River watershed. Water quality grades are given to sections of the rivers and streams based on how often they comply with state swimming and boating standards. Click the map to enlarge.


VOLUNTEER MONITOR RESOURCES

The Mystic Monitoring Network Water Quality Manual was designed to provide an explanation of the protocols and procedures for water quality sampling, as well as some background on the parameters being tested. Volunteers are expected to familiarize themselves with these procedures to ensure that the data collected are as accurate as possible.
