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 Detected, below limit Limit 10 ppt | 8.7 ppt 87% of the limit |
| 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 | 0.87 |
| PFBS Detected, below limit Guideline 2,000 ppt | 7.38 ppt |
| PFBA Detected, below limit Guideline 6,000 ppt | 7.8 ppt |
| PFHxA Detected, below limit Guideline 3,000 ppt | 1 ppt |
| PFPeA Detected, no limit | 0.75 ppt |
29 PFAS tested, 5 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
Detected in 4 of 4 samples. Highest result 50.1 ppb. EPA's non-enforceable screening level is 10 ppb. Above screening level The screening level is how EPA decides what to study further, not a health limit. There is no federal limit for lithium and no filter is certified to remove it. About lithium.
Lead and copper
Latest 90th percentile: 3.95 ppb lead (Jan 2022 – Dec 2024). Below action level
Highest since 2016: 4.3 ppb (Dec 2016).
| Monitoring period | Lead (90th pct.) |
|---|---|
| Jan 2022 – Dec 2024 | 3.95 ppb |
| Jan 2019 – Dec 2021 | 4 ppb |
| Jul 2018 – Dec 2018 | 3.65 ppb |
Earlier results (9)
| Jan 2018 – Jun 2018 | 3.39 ppb |
| Jan 2014 – Dec 2016 | 4.3 ppb |
| Jan 2013 – Dec 2013 | 4.89 ppb |
| Jan 2010 – Dec 2012 | 10.9 ppb |
| Jan 2007 – Dec 2009 | 0 ppb |
| Jan 2004 – Dec 2006 | 15.6 ppb |
| Jan 2001 – Dec 2003 | 6.3 ppb |
| Jan 1998 – Dec 2000 | 10 ppb |
| Jan 1995 – Dec 1997 | 6.4 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 |
|---|---|
| Jul 2024 – Oct 2024 2 times | The running annual average for TTHM was above the legal limit. EPA record: TTHM · Maximum Contaminant Level Violation, Average · measured 0.086 mg/l (limit 0.080 mg/L) 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 | 10.4 ppb | 300 ppb |
| Chlorate | 33 ppb | 210 ppb |
| Vanadium | 0.38 ppb | 21 ppb |
| Strontium | 2.2 ppm | 1.5 ppm |
