PFAS (“forever chemicals”)
EPA UCMR 5: 1 entry point tested Apr 2023 to Jan 2024. "Average" is the highest entry-point average (non-detects counted as zero), the way EPA compares UCMR 5 results to the limits. ppt = parts per trillion. These results do not determine compliance.
| Contaminant | Highest average |
|---|---|
| PFOA Not detected Limit 4 ppt | – |
| PFOS Not detected Limit 4 ppt | – |
| PFHxS Not detected Limit 10 ppt | – |
| PFNA Not detected Limit 10 ppt | – |
| HFPO-DA (GenX) Not detected Limit 10 ppt | – |
| Hazard Index (a combined score for PFHxS, PFNA, GenX and PFBS, where above 1 is over the limit) Not detected Limit 1 | – |
| PFBS Not detected Guideline 2,000 ppt | – |
| PFBA Not detected Guideline 6,000 ppt | – |
| PFHxA Not detected Guideline 3,000 ppt | – |
Pennsylvania has its own PFAS limits. PFOA 14 ppt (this system's highest average: not detected), PFOS 18 ppt (this system's highest average: not detected). State compliance is judged on the state's own sampling, so ask the utility or the state program whether it meets them.
29 PFAS tested, 0 detected at least once. "Not detected" means below EPA's reporting limit (about 2 to 20 ppt depending on the chemical), not proven zero. PFAS not listed were not detected. The limits for PFHxS, PFNA, GenX and the Hazard Index were proposed for rescission in May 2026. That proposal is not final. Systems have until 2029 to meet the limits.
Lithium
Not detected in 4 samples (reporting limit 9 ppb). About lithium.
Lead and copper
Latest 90th percentile: 3.48 ppb lead (Jun 2025 – Sep 2025). Below action level
| Monitoring period | Lead (90th pct.) |
|---|---|
| Jun 2025 – Sep 2025 | 3.48 ppb |
| Jun 2022 – Sep 2022 | 0 ppb |
| Jun 2019 – Sep 2019 | 0 ppb |

| Jan 1999 – Dec 1999 | 5.8 ppb |
| Jul 1997 – Dec 1997 | 7.1 ppb |
Lead comes from pipes and fixtures, not the source water, so it varies home to home. The 90th percentile means 9 in 10 sampled homes were at or below it. More on lead.
Violations
| When | What happened |
|---|---|
| Oct 2018 – Jan 2019 2 times | The system did not remove enough organic matter, which reacts with chlorine to form disinfection byproducts. EPA record: Carbon, total · Treatment Technique Precursor Removal (limit TT ) Resolved |
Health-based violations mean a contaminant exceeded a limit or a required treatment step was missed. Monitoring and reporting violations mean required tests or reports were late or missing, so the water's quality during that time is unknown. The total includes every violation in EPA's records, most of them paperwork.
Earlier EPA testing (2013–2020)
| Contaminant | Highest | Guideline |
|---|---|---|
| Manganese | 5.02 ppb | 300 ppb |
| Chromium-6 | 0.09 ppb | – |
| Chlorate | 30 ppb | 210 ppb |
| Strontium | 0.14 ppm | 1.5 ppm |
