PFAS (“forever chemicals”)
EPA UCMR 5: 1 entry point tested Mar 2024 to Dec 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 | – |
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: 0.8 ppb lead (Jan 2023 – Dec 2025). Below action level
Highest since 2016: 0.94 ppb (Dec 2022).
| Monitoring period | Lead (90th pct.) |
|---|---|
| Jan 2023 – Dec 2025 | 0.8 ppb |
| Jan 2020 – Dec 2022 | 0.94 ppb |
| Jan 2017 – Dec 2019 | 0.63 ppb |
Earlier results (9)
| Jan 2016 – Jun 2016 | -1 ppb |
| Jul 2015 – Dec 2015 | 1.2 ppb |
| Jan 2012 – Dec 2014 | 0 ppb |
| Jan 2009 – Dec 2011 | 2 ppb |
| Jan 2006 – Dec 2008 | 4 ppb |
| Jan 2003 – Dec 2005 | 5 ppb |
| Jan 2003 – Dec 2003 | 5 ppb |
| Jan 2002 – Dec 2002 | 3 ppb |
| Jan 2001 – Dec 2001 | 9 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
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 | 0.42 ppb | 300 ppb |
| Chromium-6 | 0.11 ppb | – |
| Vanadium | 0.27 ppb | 21 ppb |
| Strontium | 0.31 ppm | 1.5 ppm |
| Chlorate | 192 ppb | 210 ppb |
