PFAS and lithium
7 compounds detected at or above the reporting limit under EPA’s UCMR 5 monitoring, across 11 samples.
| Compound | Highest detected | Samples | Most recent |
|---|---|---|---|
| lithium | 9.1 µg/L | 1 | 2/14/2024 |
| PFOA | 0.015 µg/L | 2 | 6/17/2024 |

A detection is a measurement, not a violation and not a health finding. EPA states that UCMR 5 results do not indicate compliance or non-compliance with any limit.
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
No hardness measurement. Hardness is measured at environmental monitoring stations, and none fell inside this system’s service area. That is a gap in where monitoring happens, not a finding about the water.

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.
