St. Croix County’s June nitrate screening clinic in Baldwin drew 126 participants, with 37% of untreated samples testing above the federal health standard of 10 mg/L. These results are higher than the county average, highlighting the importance of regular well water testing, especially for households relying on private wells. Free nitrate screenings will continue throughout the summer and fall at locations across the county. The clinics are coordinated by St Croix County Land and Water Conservation and Public Health.
