Water Quality Program

 

Hudson River Estuary
Find the latest data from the Hudson River Estuary, as well as data from 2006, when we began sampling the Hudson. Our routine monitoring of 74 locations between New York Harbor and Waterford began in 2008. All data is gathered in partnership with CUNY Queens College and Columbia University’s Lamont-Doherty Earth Observatory.

Tributaries and Waterfronts
In partnership with community scientists and dozens of organizations, we test many tributaries of the Hudson, and water access sites, for fecal indicator bacteria and other water quality indicators. These samples are collected from the water’s edge by Riverkeeper-trained community scientists, and processed in our onboard lab, our lab in Kingston, or one of our partner labs. We encourage communities to use this data to restore and protect their local waterways.

Water Quality Reports
Find past How’s the Water? reports, as well as reports detailing analysis of data gathered in each tributary watershed we sample, including the Mohawk River, Upper Hudson, Catskill Creek, Esopus Creek, Rondout Creek, Wallkill River, Roeliff Jansen Kill, Saw Kill, Pocantico River, Saw Mill River and Sparkill Creek.

Scientific Publications
Our partners at Columbia University’s Lamont-Doherty Earth Observatory and CUNY Queens College, and scientists at other institutions, have published many studies in the scientific literature, based on our water quality monitoring projects.
