A Kewaunee County Board committee Tuesday will consider supporting a bill that would award grants to counties to help cover the costs of improving private wells that have been contaminated by nitrates.

Senate Bill 137, co-sponsored by state Sen. Robert Cowles, R-Green Bay, and state Rep. Joel Kitchens, R-Sturgeon Bay, would require the state Department of Health Services to award grants of up to $2,500 to eligible private well owners to cover remediation costs for nitrate levels exceeding 10 parts per million.

Eligible costs include well testing, installation of an appropriate filtration system, replacement of the well or replacement of the water supply, according to analysis of the bill by the Legislative Reference Bureau.

Counties may also receive up to $500,000 to reimburse the actual costs of administering the testing and reporting requirements.

Ten parts per million is the maximum contaminant level allowed for nitrates under the U.S. Safe Drinking Water Act.

A resolution regarding the bill is on the agenda for consideration by the county Land & Water Conservation Committee when it meets at 8:15 a.m. Tuesday at the Kewaunee County Fairgrounds building, 625 Third St., Luxemburg.
