For 20 weeks starting in May, nearly 70 volunteer citizen scientists from local boathouses and community groups collect weekly water samples for the Citizens’ Water Quality Testing Program (CWQTP) at boat launches and docks from Yonkers to Jamaica Bay. All samples are tested for microbes of the genus Enterococcus using the US EPA approved IDEXX Enterolert protocols.

Enterococci live in the feces of humans and other warm-blooded animals. Their presence in the water is an indication of fecal pollution and the possible presence of pathogens that could be harmful to human health. Combined sewer overflow discharges and storm water runoff from streets are the primary contributors to fecal pollution in the Hudson River. By gathering this information it is sought to create a baseline of data that, when correlated with rain and tide information, can help better inform boaters and other recreational users of the harbor of likely water quality at their preferred access points and launch sites, that they may interpret our results and make informed decisions about utilizing the harbor safely.
Results are disseminated to the public via the New York City Water Trail Association website, social media, and email blast every Friday evening throughout the boating season.
If you would like to volunteer or be added to the water testing email list please send an email to firstname.lastname@example.org.
