Drinking Water Quality

In order to ensure high quality drinking water for nine million consumers (nearly half the population of New York State), DEP conducts an extensive water quality monitoring program that encompasses all areas of the Catskill/Delaware and Croton Watersheds. Water quality sampling sites include meteorological stations, watershed streams, water supply reservoirs, wastewater treatment plants, and key aqueduct points.

DEP’s comprehensive watershed monitoring network not only serves as the scientific basis for assessing changes in watershed conditions and water quality, but it contributes to the ongoing review and refinement of the City’s watershed protection program. Perhaps most importantly, DEP’s watershed monitoring network continues to demonstrate that New York City’s drinking water supply easily meets all health-related State and federal drinking water standards.
