Water Testing for Private Wells

Due to the current COVID-19 pandemic the Vernon County Water Lab will not be accepting samples for analysis.

Forty percent of Wisconsin residents get their drinking water from private wells. It is recommended that all wells used for drinking water test for bacteria and nitrate annually or anytime there is a change in appearance, odor, or taste. It is also recommended to test for arsenic at least once, more frequently if arsenic is found in the sample. 

Vernon County Health Department is a DATCP Certified Water Testing Laboratory for Bacteria. We also accept nitrate and arsenic samples for analysis at other laboratories. 

Water test kits can be picked up during our normal office hours of Monday -Friday, 8:30 AM to 4:30 PM

Water samples can be submitted Monday –Thursday, 8:30 AM to 4:00 PM.

The cost of testing at the Vernon County Health Department is:
