How to get your Missouri water tested for PFAS
EPA UCMR 5 tested 163 public water systems in Missouri — 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.

Missouri testing resources
- State agency
- Missouri Department of Natural Resources (MoDNR) · state PFAS page
- PFAS limits
- Missouri has no PFAS standards of its own and follows the federal EPA limits.
- State help
- MoDNR runs voluntary PFAS occurrence monitoring of public supplies (covering 76%+ of the population); results in its PFAS Viewer Tool.
