- PFAS
- Detected, below limit8 of 29 PFAS found at least once. All averages below the federal limits.

PFAS (“forever chemicals”)
EPA UCMR 5: 3 entry points tested Jul 2023 to Apr 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 One sample above limit Limit 4 ppt | 2.25 ppt 56% of the limit |
| PFOS Detected, below limit Limit 4 ppt | 1 ppt 25% of the limit |
| PFHxS Detected, below limit Limit 10 ppt | 0.75 ppt 8% 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 | 0.077 |
| PFBS Detected, below limit Guideline 2,000 ppt | 4.83 ppt |
| PFBA Detected, below limit Guideline 6,000 ppt | 10 ppt |
| PFHxA Detected, below limit Guideline 3,000 ppt | 9 ppt |
| PFPeA Detected, no limit | 8.93 ppt |
| PFHpA Detected, no limit | 1.6 ppt |
29 PFAS tested, 8 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 5 of 12 samples. Highest result 9.99 ppb. EPA's non-enforceable screening level is 10 ppb. Below 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: 1 ppb lead (Jan 2022 – Dec 2024). Below action level
| Monitoring period | Lead (90th pct.) |
|---|---|
| Jan 2022 – Dec 2024 | 1 ppb |
| Jan 2019 – Dec 2021 | 0 ppb |
| Jan 2016 – Dec 2018 | 1 ppb |
Earlier results (9)
| Jan 2013 – Dec 2015 | 2 ppb |
| Jan 2010 – Dec 2012 | 2.72 ppb |
| Jan 2007 – Dec 2009 | 5.93 ppb |
| Jan 2004 – Dec 2006 | 4.6 ppb |
| Jan 2001 – Dec 2003 | 2.3 ppb |
| Jan 1998 – Dec 2000 | 4.9 ppb |
| Jan 1995 – Dec 1997 | 3.4 ppb |
| Jan 1994 – Dec 1994 | 3.5 ppb |
| Jan 1993 – Dec 1993 | 3.6 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 | 11.2 ppb | 300 ppb |
| Molybdenum | 3 ppb | 40 ppb |
| Chromium-6 | 0.45 ppb | – |
| 1,4-Dioxane | 0.12 ppb | 0.35 ppb |
| Strontium | 0.46 ppm | 1.5 ppm |
| Chlorate | 80 ppb | 210 ppb |
| Vanadium | 0.69 ppb | 21 ppb |

For the official word, read the utility's annual Consumer Confidence Report.
