Welcome to the Alternative Water Program!

The Alternative Water Program (AWP) provides free nitrate testing for eligible residents who receive their drinking water from a private well or a Group B water system.

The program was originally launched in 2024 to select Benton-Franklin Health District (BFHD) programs and partner organizations. Due to its success, the program has expanded and is now available to eligible residents throughout Benton and Franklin counties.

If you receive your drinking water from a private well or a Group B water system, you may qualify for a free nitrate test. If elevated nitrate levels are detected, additional resources and assistance may be available to help protect your household's drinking water.

Use the information on this page to learn about eligibility requirements, request a test, understand your results, and explore available resources.

To obtain a free nitrate testing bottle, visit the Environmental Health desk on the second floor of our Kennewick office, call 509-460-4205, or email [email protected].


Already Tested Your Well?

If you have already tested your private well within Benton or Franklin County and your nitrate level is 10 mg/L or greater, you may qualify to receive a free Reverse Osmosis (RO) countertop unit through the Alternative Water Program.

To be considered, you must:

  • Have a nitrate test result of 10 mg/L or greater from a private well or Group B water system in Benton or Franklin County.
  • Meet the program's household eligibility requirements.

If you do not have a copy of your nitrate test results, our staff may be able to help locate them or discuss whether additional testing is needed.

About the Nitrate Map

This map displays nitrate sampling results for wells in Benton and Franklin counties. The map is intended to show raw well water nitrate levels; however, the treatment status of some water sources represented in the dataset has not yet been confirmed. As a result, some results may reflect either raw (untreated) or treated water samples. The data and map will be updated as source and treatment information are verified.

Data Sources

Nitrate sampling data were obtained from the Washington State Department of Health (DOH) Drinking Water Program, the Washington State Department of Ecology Environmental Information Management (EIM) system, and the Benton-Franklin Health District Water Laboratory Chemical Testing Database.
