## Contaminants measured

| Contaminant | Category | Measured level | Sampling context | Federal limit | Status |
|---|---|---|---|---|---|
| Fluoride | Inorganic chemicals | 0.2 mg/L (Average) | System-wide | 4 mg/L (MCL) | Within the limit |
| Arsenic | Metals | 2 ug/L (Average) | System-wide | No federal limit | Within the limit |
| Nitrate Nitrite | Other | 1.1 mg/L (Average) | System-wide | 10 mg/L (MCL) | Within the limit |
| Gross Alpha | Radionuclides | Not detected pCi/L (Average) | System-wide | 15 pCi/L (MCL) | Within the limit |

## What these contaminants are

- **Fluoride** — A mineral often added to drinking water to help prevent tooth decay. Beneficial at low levels, but long-term exposure above the federal limit can cause bone disease and tooth mottling.
- **Arsenic** — A naturally occurring element that also enters water from industry and agriculture. A known human carcinogen; long-term exposure is linked to skin, bladder, and lung cancer.
- **Gross Alpha** — Gross alpha particle activity — a combined measure of alpha-emitting radioactive substances. Long-term exposure above the federal limit increases cancer risk.

## How to read this

- A water-quality report covers an entire service area, not a single address.
- 'Federal limit' is the EPA standard (MCL, action level, treatment technique, etc.) that the measured level is compared against.
- 'At or above the federal limit' means the utility's own reported figure met or exceeded that standard.
