Streams are often at the receiving end of rainfall (stormwater) runoff from land surfaces and local stormwater drain-pipe systems. Stormwater pollution, as well as sewage from leaky sewer lines and contamination from landfills, can shock a stream system for a brief period. But if these influences are persistent and repeated, they can degrade streams and the aquatic habitat for insects, fish, stream salamanders, and other biological communities.
Water monitoring identifies where pollution is degrading stream conditions and helps DEP to prioritize its watershed restoration efforts. Learn how you can help protect our watersheds.
