Nitrate/Nitrite Well Water Testing
July 29 - Mason County
July 30 - Lake County


On July 29 and 30 samples from drinking water wells will be screened for nitrate and nitrite. This service is for private drinking water wells only.

Please review this flyer for site-specific information.

Public water supplies are tested regularly. Please do not bring samples from public water supplies or non-drinking water sources. Only drinking water well samples will be tested. You do not have to use a special bottle for this screening. Any small clean jar will work—one ounce of water is enough.

Please follow the directions below to sample your well. Collect samples just before getting them to the sample drop-off. Samples must be less than 48 hours old for a valid nitrate result.

1. Fill out the water Sample Information Sheet.

2. Pick a tap that supplies water that has not run through any treatment devices (water softener, carbon filter, etc.). An outdoor faucet often works well.

3. Run the water for 20-30 minutes before collecting the sample. This will give the pump time to flush the water pressure tank and plumbing so you can collect a valid sample. Disconnect any hoses before collecting the sample; do not sample through a hose. Rinse the sample bottle and lid thoroughly in the water to be sampled; then fill and cap the bottle.

4. Label the bottle clearly with your name, the sampling date, and the well name (cottage well, Mom's well, etc.) using a waterproof pen.

5. Keep the sample dark and cold (on ice or refrigerated) until it is dropped off.

All results are confidential. You will be mailed a copy of your results in 8 to 10 weeks, with information about what to do if the concentration of nitrate or nitrite is too high.

Be sure to fill out the Sample Information Sheet completely and bring it with your water sample to the drop-off.  We need a complete mailing address to get your results back to you.  You can get more information from The Mason-Lake Conservation District Office at 231-757-3707 x5, or from your local MAEAP stewardship technician at 231-757-3707 x109.
