Well Water Testing in Wisconsin

The Wisconsin DNR recommends testing a private well for bacteria once a year and any time the water changes taste, color or smell, and for nitrate once a year and before someone who is or may become pregnant drinks it. Most well users should test for arsenic every five years, and every year in Outagamie, Winnebago and Brown counties.

Tests go to a Wisconsin certified laboratory, which supplies the sampling kit, and a sample has to reach the lab within 48 hours. Some well and pump companies collect the sample for you, test as part of a new well or pump job, or install treatment when a result comes back high. The companies below test well water in Wisconsin.
