Water Quality Testing Program

In a break from current water testing practices, Riverkeeper has launched a program to take samples the length and breadth of the Hudson – at deep-water sites, boat launches, public piers, swimming beaches, mouths of tributaries, and off wastewater treatment plants –and then bring the results to you, the public.

Before this program started, water testing on the Hudson was not happening very often, samples were only taken from the middle of the river, results were expressed in averages and general trend, and it was hard for the public to get hold of the information.

Using our 36-foot patrol boat, Riverkeeper and scientists from Lamont-Doherty Earth Observatory of Columbia University and Queens College of the City University of New York, have tested more than 1,000 samples from over 80 locations and published the findings online.
