WATERSHED ISSUES
The Mystic River Watershed has a long history of industrialization, that while allowing our communities to prosper economically has resulted in a legacy of contamination that continues to effect our waterbodies today. As we proceed to learn about these effects, we are seeing slight improvements in water quality. View the pages listed below for additional information about issues currently impacting the Mystic River Watershed.
SANITARY SEWER OVERFLOWS (SSO's)
Sanitary sewer overflows, or SSOs, are discharges of raw sewage into surrounding water sources and communities that pose as a substantial public health risk. MyRWA addresses SSOs through data management, advocacy and outreach.
COMBINED SEWER OVERFLOWS (CSO's)
Have you ever wondered if it is safe to swim or boat in the Mystic River? Some days, especially after a heavy rain, a swimming or boating advisory may be issued by the local municipality.
STORMWATER & RUN-OFF
(Non-Point Source Pollution)
Run-off is a major cause of water pollution in the Mystic River and its tributaries, affecting fisheries, habitat quality, flora and fauna, and the overall beauty of the river.
Are the fish contaminated? Check out the Public Health Fish Advisory to find out more about the health of fish in the Mystic River.
The Mystic River Watershed hosts many invasive species, or non-native species that negatively impact the ecosystem.
The Mystic River Watershed is home to three EPA sanctioned Superfund sites, or areas of toxic waste. Learn more about Superfund sites and what is being done to clean them up here.
