By joining Salt Watch and Nitrate Watch, you can help track chloride and nitrate levels in local streams and wells, providing critical data to scientists and policymakers. Your observations help identify pollution hotspots and advocate for smarter water management. Get involved today—protecting clean water starts with you! Your participation during April will count toward One Million Acts of Science, helping monitor water quality while connecting with nature.
