Although water quality has improved in the watershed, there are several potential sources of problems.
Point Source pollution could include discharges from industries along the river or sewage treatment plants in Stafford, Coventry, and the University of Connecticut Storrs campus.
Non-point Source pollution come from broadly distributed sources and could include chemicals or sediments caused by
- erosion from farmland and construction sites,
- stormwater runoff from streets,
- buildings and parking lots in the watershed,
- removal of streamside wetlands and vegetation that absorb sediments and chemicals before they reach the water.
