2026 IDEM Office of Water Quality Groundwater Monitoring Network (GWMN) Survey

The GWMN is a statewide groundwater quality study. We typically get our samples from private residential drinking water wells. Your assistance will help us get the best possible data for this study. Unfortunately, not everyone that signs up will be able to be sampled. If you are selected for sampling, we will notify you prior to our visit and provide you with a copy of the sampling results at the end of the sampling season. We appreciate your participation in our study by initially completing this survey to the best of your knowledge.
