All MDA services should now be working after Friday's worldwide vendor technology outage. We apologize for any inconvenience this may have caused.

Beginning September 1, the application of nitrogen fertilizer in the fall and on frozen soil will be restricted in areas vulnerable to groundwater contamination. This will also apply to Drinking Water Supply Management Areas (DWSMAs) with elevated nitrate levels.

MDA staff have prepared a presentation to explain the purpose of the Groundwater Protection Rule, where the nitrogen fertilizer restrictions apply, and the exceptions to the rule. View the prerecorded presentation or the recorded webinar to learn more (details below).
