Groundwater
Groundwater
Every Pierce County resident relies on groundwater. Public water supplies are regularly tested and regulated by drinking water standards. Private wells are not required to be regularly tested or required to take corrective action, it is up to the well owner.
Water testing
The Wisconsin DNR recommends (Link to document):

Certified drinking water labs close to Pierce county
Homeowners test kits from the UW-Stevens Point lab are available for pick up in the Land Conservation office.
If you are interested in further private well testing or have other questions about groundwater the Center for Watershed Science and Education at UW-Stevens Point is a great resource
Well Specific information
A well log is a wealth of information about your well including it’s: age, depth, casing type etc. Search the DNR well log records by address. If you would like assistance finding or reading your well log please contact Retta (retta.isaacson@co.pierce.wi.us) Well Abandonment: Wells no longer used or maintained should consider formal abandonment and closure because they act as direct conduits to groundwater and make it more vulnerable to contamination from the surface. Most well abandonments are eligible for costing sharing assistance- please contact the Land Conservation Dept. for details. |
