WisDNR now taking applications for contaminated well funding

By Patrick Lynn

The Wisconsin Department of Natural Resources is now accepting applications for its new contaminated well program.

With $10 million in funding through the American Rescue Plan Act (ARPA), the DNR will fund eligible applications to its Well Compensation and Well Abandonment Grant Programs until funding runs out.

The program provides financial assistance to private well owners to address contamination in their wells by awarding grants for the replacement, reconstruction, treatment, or abandonment of their wells.

The eligibility criteria for both programs have been expanded beyond the previous Well Compensation Grant Program, and many previously ineligible individuals will now be eligible to apply, according to a Monday news release from the DNR.

Expanded eligibility criteria include the following changes:

  • Any well contaminated with nitrate at concentrations at or above the state’s public health standard of 10 parts per million (ppm) is now eligible. Previously, only nitrate-contaminated wells with concentrations above 40 ppm that were used as a water supply for livestock were eligible.
  • Any well contaminated with arsenic at concentrations at or above the federal drinking water standard of 10 parts per billion (ppb) is now eligible. Previously, only arsenic-contaminated wells above the threshold of 50 ppb were eligible. The arsenic threshold for arsenic-contaminated wells has been lowered from 50 ppb to 10 ppb to comply with federal drinking water standards.
  • Any well with a source of bacterial contamination that presents a human health risk is now eligible for the program. Previously, only wells contaminated with fecal bacteria caused by livestock were eligible.
  • A well with PFAS exceeding the drinking water standard in Ch. NR 809 (70 parts per trillion for PFOA+PFAS) or subject to an advisory from the Department of Health due to the levels of PFAS in the well is eligible for Well Compensation.


All applicants must provide results of two water samples, taken at least two weeks apart, that confirm the contamination in their well. Samples must be tested at a certified laboratory, and testing needs to have been done within the last two years of the application date to be eligible.

The expanded eligibility criteria include changes to income requirements, increasing from $65,000 to $100,000 annually. Income eligibility will be based on the business owner’s income instead of family income.
