2015 Sampling Data

Westchester County & Greenwich, CT
Summary by Site
Quality Assurance Project Plan

Explore the map below for a summary of each location. The colors reflect the average bacteria levels (the “geometric mean”), which gives a sense of how high the fecal contamination levels can get at each site. The “% Pass” and “% Fail” show how many samples passed or failed the single sample criteria for safe swimming.

Save the Sound sampling efforts were expanded significantly for the 2015 sampling season. With the aid of 24 trained volunteers, we collected approximately 400 water samples at 52 sites from Pelham, New York to Greenwich, Connecticut. We tested each sample for the fecal indicator bacteria Enterococcus and scored each sample as “pass” or “fail” based on the New York and Connecticut safe swimming criteria.

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.
  • If you see sewage overflowing in your community, please let us know by sending a photograph or video and the time and location of the overflow to pollution@savethesound.org.
