## Contaminants measured

| Contaminant | Category | Measured level | Sampling context | Federal limit | Status |
|---|---|---|---|---|---|
| Copper | Metals | 5 ug/L (Reported level) | No. of Samples Collected | No federal limit | Within the limit |
| Escherichia coli (E. coli) | Microbial | 0 (Highest single sample) | No. of Detections | 0 (MCLG) | None detected |
| Total Coliform | Microbial | 1 (Highest single sample) | No. of Detections | 0 (MCLG) | Detected — no federal limit |
| Turbidity | Physical & aggregate | 1 (Reported level) | System-wide | No federal limit | Detected — no federal limit |

## What these contaminants are

- **Copper** — A metal that enters water from corroding household plumbing. Short-term exposure causes stomach distress; long-term exposure can damage the liver and kidneys.
- **Escherichia coli (E. coli)** — Escherichia coli — bacteria found in the gut of humans and animals. Its presence in drinking water indicates fecal contamination and a real risk of waterborne illness.
- **Total Coliform** — A group of bacteria used as an indicator of overall water-system sanitation. Coliforms themselves are usually harmless, but their presence signals that disease-causing organisms could enter the system.
- **Turbidity** — A measure of cloudiness from suspended particles in the water. High turbidity can shelter microbes from disinfection; the EPA enforces it through a treatment-technique standard.

## 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.
