PFAS and lithium
6 compounds detected at or above the reporting limit under EPA’s UCMR 5 monitoring, across 43 samples.
| Compound | Highest detected | Samples | Most recent |
|---|---|---|---|
| PFBA | 0.0082 µg/L | 5 | 4/10/2023 |
| PFOS | 0.0073 µg/L | 8 | 7/11/2023 |
| PFPeA | 0.007 µg/L | 8 | 7/11/2023 |
| PFHxA | 0.0061 µg/L | 8 | 7/11/2023 |

| PFBS | 0.0049 µg/L | 7 | 7/11/2023 |
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
Median hardness 25 mg/L as CaCO₃, measured at 2 stations serving this system across 67 results, 2016-05-16 to 2026-05-21. Measured in the water source and distribution area, not at a tap, and not in your home.

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
1 open health-based violation(s) recorded in SDWIS and not yet returned to compliance.
- MCL · contaminant code 2950 · began 2019-10-01
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.
