About this data: ClearWater uses the EPA's Safe Drinking Water Information System (SDWIS). Data is for public water systems only; private wells are not included. Legal limits (MCLs) are minimum standards; some contaminants may still pose health risks below legal thresholds.

Lead & Copper
| Measure | Result | EPA action level | Status | Monitoring period |
|---|---|---|---|---|
| Lead (90th percentile) | 0.001 mg/L | 0.015 mg/L | Below action level | 2024-12-31 |
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.
