The Citizen Groundwater Monitoring Program (CGMP) is a 5-year groundwater study that began in the fall of 2019. The program aims to understand long-term trends in groundwater nitrate contamination throughout the County through annual sampling of the same wells for the program duration, and provides participants with five years of free water testing. The program also aims to gain a better understanding of St. Croix County groundwater aquifer health and determine the primary factors that contribute to a private drinking water well’s susceptibility to contamination in St. Croix County. The program samples private wells on a voluntary basis across the county and would not be possible without citizen participation.

 

Participating landowners will receive their sample kits by October 20. Please follow the instructions included in the kit and return the sample to one of the approved locations.
