How to get your North Dakota water tested for PFAS
EPA UCMR 5 tested 34 public water systems in North Dakota — 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.
