Private Drinking/Well Water Testing
As private wells are not regulated, it is up to the well owner to have their well tested regularly. The National Ground Water Association (NGWA), the Environmental Protection Agency (EPA), the WI Department of Natural Resources (DNR) and Sawyer County Health & Human Services all recommend well owners to test their water at least annually for bacteria, nitrates, and any contaminants of local concern. More frequent testing should be considered if:
- There is a change in the taste, odor, or appearance of the well water, or if a problem occurs such as a broken well cap, inundation by floodwaters, or a new contamination source
- The well has a history of bacterial contamination
- The septic system has recently malfunctioned
- Family members or house guests have recurrent incidents of gastrointestinal illness
- An infant is living in the home
- To monitor the efficiency and performance of home water treatment equipment, or
- Your water hasn’t been tested for a while.
Remember, a test can only tell you about the quality of the water at the time of the test - the quality may change at different times. If concerned arrange for a retest of your well water.

How and When Am I Notified of My Results?
Bacteria results will be available within two business days and Nitrates/Arsenic results take 2 - 3 weeks. We will notify you of your sample results vial mail or email. We would prefer to email you the results to save on postage. Your sample results will remain on file for seven years.
What Should I Do If The Results Indicate There Is A Problems With My Well Water?
If your water test results indicate a presents of Coliform Bacteria, we recommend re-testing the water to confirm the results of the first test and rule out possible sampling error. Upon conclusion of the re-test, and the water is deemed unsafe, we suggest your contact you Sawyer County Health Department for additional information 715-634-4806.
