Introducing Nitrate Pollution Awareness Week!
July 26 – August 1, 2026
Nitrate Pollution Awareness Week is an initiative of the Izaak Walton League of America dedicated to increasing public understanding of nitrate pollution, its sources, environmental and public health impacts, and the risks it poses to our waterways and communities.
Join us for a week of water monitoring, education, and advocacy as we work together to protect and improve water quality.
Your kit will include a bottle containing 25 nitrate test strips which you can use to test your water source(s) throughout the year. You’ll also receive postcards explaining how to use your nitrate test strips and how to share your Nitrate Watch results on the Clean Water Hub.
Your kit will include four test strips so you can test your waterway throughout the season. You’ll also receive a chart to help you interpret your results and a postcard with instructions for completing a Salt Watch test and reporting your findings.
