PFAS and lithium
2 compounds detected at or above the reporting limit under EPA’s UCMR 5 monitoring, across 6 samples.
| Compound | Highest detected | Samples | Most recent |
|---|---|---|---|
| lithium | 26 µg/L | 5 | 7/9/2024 |
| PFBA | 0.0055 µg/L | 1 | 10/15/2024 |
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
7 open health-based violation(s) recorded in SDWIS and not yet returned to compliance.

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.

Hardness
Median hardness 40 mg/L as CaCO₃, measured at 3 stations serving this system across 44 results, 2015-02-11 to 2021-09-20. 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.
