Make a Plan to Monitor

If you plan to participate in Nitrate Watch, you’ll need to make a plan! Each Nitrate Watch kit includes 25 nitrate test strips. Your goal will be to use each and every test strip and report your data on the Clean Water Hub.

The Make a Plan worksheet is a tool to help you plan out when and how you will use your nitrate test strips. Download it and start planning!

Hand Out Flyers

Use these flyers to educate your community about nitrate pollution.

Contact Local Government

Contact Your Health Department

Contact your city or county Department of Health if your drinking water contains nitrate levels above the EPA drinking water standard (10 mg/L).

Call Your Local Environmental Agency

Contact your Department of Natural Resources or Department of Environmental Quality to report consistently high nitrate levels in surface water (rivers, lakes, streams). It is also important to report harmful algal blooms caused by nutrient pollution.

Write a Letter to Your State Legislator or City Council

Consuming water with elevated nitrate levels is harmful to human health. The current regulatory limit is likely not sufficient to protect us. Ask your elected officials to support solutions to nitrate pollution!
