Lead & Copper
| Measure | Result | EPA action level | Status | Monitoring period |
|---|---|---|---|---|
| Lead (90th percentile) | 0.003 mg/L | 0.015 mg/L | Below action level | 2025-12-31 |
These are 90th-percentile results across sampled household taps, not a single measurement, and neither lead nor copper has a Maximum Contaminant Level. Lead reaches tap water from household plumbing rather than from the treatment plant, so a result below the action level does not guarantee your own tap is below it.
