Nitrate Watch Results

Nitrate Watch logo

On February 1, 2023, the Nitrate Watch program officially launched. Volunteers across the country began to request kits, monitor nitrate in water sources important to them, and report their data on the Clean Water Hub. This data joins years of nitrate data, collected as part of Save Our Streams Chemical surveys, that is already in the national water quality database.

Izaak Walton League staff will track data as it is submitted and create periodic reports using this data. The Nitrate Watch dataset is also readily accessible to anyone who is interested in learning more about nitrate pollution in their community or sharing their results with others.

Season 6 may be ending, but road salt can be even more of a problem for streams in the summer. Help us learn more about how aquatic life is affected by high chloride levels and warm weather. Ready to get involved? Request your Nitrate Watch kit now!
