How to get your Indiana water tested for PFAS
EPA UCMR 5 tested 93 public water systems in Indiana — but at the utility entry point, not your tap. Aging pipes and indoor plumbing can change what reaches your home, and private wells aren't covered by UCMR 5 at all. To find out what's actually in your water, test it with a certified lab.

Wells aren't covered by EPA testing — your own testing guide
Indiana testing resources
- PFAS limits
- Indiana follows the federal EPA MCLs and has not set its own enforceable PFAS standards.
- State help
- IDEM's free Groundwater Monitoring Network samples some private wells, but it is a general survey, not PFAS-specific. Program details →
