Part 1 one of the Groundwater Protection Rule restricts the application of nitrogen fertilizer in the fall and on frozen soils to cropland in 1) vulnerable groundwater areas or 2) those protection areas around a public well, known as drinking water supply management areas, with high nitrate.

Access the Vulnerable Groundwater Area Map. On the map, vulnerable groundwater areas are purple and drinking water supply management areas with high nitrate are green.

If this is an Emergency call 911.
