Fecal Bacteria Monitoring

Click on each site on the maps for more detail and scroll down to see what we found each week in 2022.

Save the Sound collects and tests water quality from Greenwich, CT, through Westchester County, to Queens, and into Nassau County. Samples are analyzed for fecal indicator bacteria Enterococcus in brackish water and E. coli in freshwater, which are used to determine if waters are safe for swimming. The colors reflect bacteria levels at each site showing samples that passed or failed the single sample criteria for safe swimming in New York and Connecticut.

Be a Part of the Solution

  • ​Everyone can help reduce sewage pollution sources simply by conserving water, which will lessen the wear-and-tear on our water infrastructure and reduce sewage overflows by lowering the volume of water in the system.
  • Homeowners need to repair the sewer lines that connect homes and businesses to municipal sewers, or maintain their septic systems.
  • Dog owners should put pet waste in the trash, never in a catch basin or on the street.
  • Every community and homeowner should work on strategies like creating rain gardens to help reduce runoff.
  • If you see sewage overflowing in your community, please let us know by sending a photograph or video plus the time and location of the overflow to pollution@savethesound.org.
