Water Testing   « Back

Safe, clean water is one of the most important substances in our lives - for drinking, cooking, bathing and cleaning. Municipal water systems test their water regularly to ensure it is safe, but it's up to private well owners to test their well water annually.

Water Testing Kits
Water test kits for bacteria and nitrates are available for pick-up at Lincoln County Heatlh Department Monday-Friday, 8:00 a.m. - 4:30 p.m. Water samples are accepted for testing Monday-Wednesday 8:30 a.m. - 3:00 p.m. Samples should be taken withint 24 hours of dropping the sample off at the health department. The kit includes: a sterile sample bottle, the instructions for collecting the sample and a sample information form.

When should I test my well water?
Coliform Bacteria
- Annually
- Newly constructed wells
- Wells with no testing history
- Before pregnancy and at time of birth
- Annually, if located 1/4 mile from fertilized fields or animal feed lots
Water Test
- After flooding
- Noticeable changes in the taste, odor or appearance of your water

How do I get my results?
Test results will be available approximately one week following submission to the laboratory. Results will be mailed to the person designated on the lab slip.

What do I do if the tests show there are problems with my well water?
If test results show you have coliform in your well water, a second sample should be taken to confirm the first results. If after re-testing, results still indicate your well water has coliform, contact the laboratory or Lincoln County Health Department at 715-536-0307.

If a high level of nitrate is present in your well, contact a well driller or plumber for assistance.
