Watershed Protection

Why we need the Groundwater Protection Rule

About 75% of Minnesotans get their drinking water from public and private wells. Many of these wells are susceptible to nitrate contamination from cropland fertilizers, which can make the water unsafe to drink.

Today, at least 537 public water supply wells across the state have elevated nitrate levels. About 10% of private wells in vulnerable areas exceed the Health Risk Limit (HRL), including some townships where 30% to 40% or more of private wells are unsafe to drink from!
