4. Dropping Off Samples

Accepting sample drop offs between 8am-2pm on Monday – Thursday. Results are most accurate when samples are brought to the laboratory as soon as possible after collection, so they must be dropped off within 20 hours of the collection. Samples dropped off outside of their hold times/drop off days cannot be accepted.

5. Interpreting Your Results

Once your sample has been analyzed, we will email you a detailed report. This report will include the results of all requested tests along with an explanation of what the results mean. If any results indicate a potential health concern, we will notify you immediately and recommend that you stop drinking the water until further testing or treatment can be completed.

Information from the Wisconsin DNR

The Wisconsin Department of Natural Resources offers a variety of helpful resources, including recommended well water tests, guidance for interpreting your results and information on what to test for if your water develops an unusual color, odor or taste.
