PWSID ND5101125; ND5101065; ND3101807 · ND
PFAS and lithium
Not sampled for PFAS. EPA’s UCMR 5 monitoring covered every system serving more than 3,300 people and only a sample of smaller ones. This system was not in it, so there is no result to show, which is not the same as a result showing nothing.
Health-based violations
No open health-based violation on record. This covers MCL, treatment technique and MRDL violations in SDWIS that have not been returned to compliance. It excludes monitoring and reporting violations, which are the large majority nationally, so this is not “no violations”, and SDWIS completeness varies by state.
Hardness
Median hardness 445 mg/L as CaCO₃, measured at 11 stations serving this system across 411 results, 2015-01-12 to 2024-01-08. Measured in the water source and distribution area, not at a tap, and not in your home.

What this report cannot tell you
Every figure describes water at a sampling point: a treatment plant, an entry point to the distribution system, or a monitoring station. None of it describes water arriving at your tap. Plumbing between the two can add lead and copper, and if your home was built before 1986 a test kit tells you something no federal dataset can.
