PFAS (“forever chemicals”)
EPA UCMR 5: 1 entry point tested Jan 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) Detected, below limit Limit 1 | 0.00072 |
| PFBS Detected, below limit Guideline 2,000 ppt | 1.45 ppt |
| PFBA Detected, below limit Guideline 6,000 ppt | 1.3 ppt |
| PFHxA Detected, below limit Guideline 3,000 ppt | 1.35 ppt |
| PFPeA Detected, no limit | 1.25 ppt |
29 PFAS tested, 4 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: 1 ppb lead (Jan 2026 – Jun 2026). Below action level
| Monitoring period | Lead (90th pct.) |
|---|---|
| Jan 2026 – Jun 2026 | 1 ppb |
| Jan 2023 – Dec 2025 | 0.5 ppb |
| Jan 2020 – Dec 2022 | 1 ppb |

| Jan 2008 – Dec 2010 | 2.1 ppb |
| Jan 2005 – Dec 2007 | 4.6 ppb |
| Jan 2002 – Dec 2004 | 3.9 ppb |
| Jun 1998 – Sep 2000 | 8 ppb |
| Jan 1993 – Jun 1993 | 7 ppb |
| Jul 1992 – Dec 1992 | 2 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 |
|---|---|
| Aug 2016 | The water was cloudier than allowed at least once. Cloudiness can shield germs from disinfection. Urgent public notice required What that means EPA record: Interim Enhanced Surface Water Treatment Rule · Single Turbidity Exceed (Enhanced SWTR) (limit ) 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 | 2.4 ppb | 300 ppb |
| Chlorate | 1,100 ppb | 210 ppb |
| Strontium | 0.16 ppm | 1.5 ppm |
| Chromium-6 | 0.12 ppb | – |
| Vanadium | 0.8 ppb | 21 ppb |
