EDMS Wells With Samples

This download was updated on September 30, 2025. Groundwater quality data are maintained as a part of the Statewide Groundwater Quality Monitoring Program. Data are periodically collected by sampling and testing water from a large network of groundwater monitoring wells. The data is stored in the Environmental Data Management System (EDMS) database, housed at the IDWR. The Idaho Department of Water Resources (IDWR), the Idaho National Laboratory (INL), the Idaho Department of Environmental Quality (IDEQ) and Idaho State Department of Agriculture (IDA) contribute to these data.
