**Well owners frequently get false positives because they do not properly collect the sample or they do not get it to the laboratory within the amount of hours required for an accurate test. The laboratory you work through will provide you with a water sampling kit and specific directions. It’s very important to make sure you follow their sampling directions.

Please call the Washington Ozaukee Public Health Department at 262-365-5878 if you have questions about testing your private well water or your sample results.
