Program Summary

The Dodge County Volunteer Nitrate Monitoring Network (VNMN) started in February of 2008 in order to get an accurate representation of nitrate in private drinking wells. This program helps state agencies, local governments, and the public get a better understanding of what effects our groundwater. High nitrate levels in drinking water can results in serious health effects for infants. The state’s Health Risk Limit for nitrate-nitrogen is 10.0 mg/L, but drinking water is considered impaired even if tests are above 1.0 mg/L.
