A medium sized cast iron rectangular box with eased corners consisting of two pieces connected by a hinge; raised lettering on the front: “W.S.N.Y. N.Y.C. Drinking Water Sampling Station”; elevated on cast iron pedestal; generally covered in thick silver paint. Can be opened by a professional. The sampling station is approximately 4′-6″ (1.37m) high.


Found on sidewalks curbside in close proximity to water mains.


Throughout the Five Boroughs, clustering in dense population areas and specific water pressure zones.



As of August 2019, DEP has 965 sampling stations citywide. DEP scientists analyze these samples for bacteria, chlorine levels, pH, inorganic and organic compounds, turbidity, odor, and many other water quality indicators.
