INDIANA -- The Indiana Department of Environmental Management (IDEM) is encouraging eligible homeowners to apply for free well water testing through the 2026 Groundwater Monitoring Network. 

IDEM announced on Friday they are strongly encouraging residents who rely on private drinking water to test their wells regularly because private well water is unregulated by the IDEM and the US Environmental Protection Agency.

IDEM's Office of Water Quality Drinking Water Branch periodically collects samples from qualified private wells to learn more about groundwater conditions, track environmental changes and identify areas that may be subject to by natural geology or human activity.

Applicants selected for testing will be contacted by IDEM to arrange sample testing between June and October, and results will be shared directly with the homeowner.

To be considered for the 2026 survey, homeowners must:

• Reside in Indiana and has an active, private residential drinking water well
• Ensure the well is listed in the Indiana Department of Natural Resources (DNR) Online Water Well Record Database
• Be able to provide IDEM with a copy of their water well record
• Complete the survey online no later than June 1.
