## Contaminants measured

| Contaminant | Category | Measured level | Sampling context | Federal limit | Status |
|---|---|---|---|---|---|
| HAA5 | Disinfection byproducts | 26 ug/L (Running annual avg) | System-wide | 60 ug/L (MCL) | Within the limit |
| TTHM | Disinfection byproducts | 74 ug/L (Running annual avg) | System-wide | 80 ug/L (MCL) | Approaching the limit |
| Fluoride | Inorganic chemicals | 0.78 mg/L (Highest single sample) | System-wide | 4 mg/L (MCL) | Within the limit |
| Barium | Metals | 0.0394–0.045 mg/L (Range) | System-wide | 2 mg/L (MCL) | Within the limit |
| Copper | Metals | 0.53 mg/L (90th percentile) | At the tap | 1.3 mg/L (Action level) | Within the limit |
| Lead | Metals | 0 ug/L (90th percentile) | At the tap | 15 ug/L (Action level) | Within the limit |
| Atrazine | VOCs & pesticides | 0.217–0.511 ug/L (Range) | System-wide | 3 ug/L (MCL) | Within the limit |

## What these contaminants are

- **HAA5** — Haloacetic acids — a group of five disinfection byproducts formed when disinfectants react with organic matter. Long-term exposure above the federal limit is associated with an increased cancer risk.
- **TTHM** — Total trihalomethanes — a group of four chemicals (including chloroform) formed when chlorine reacts with natural organic matter. Long-term exposure above the federal limit is linked to liver, kidney, and central-nervous-system effects and increased cancer risk.
- **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.
- **Barium** — A metal from erosion of natural deposits and industrial discharge. Long-term exposure above the federal limit can raise blood pressure.
- **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.
- **Lead** — A toxic metal that leaches into water from old service lines, solder, and plumbing fixtures. There is no safe level of lead; it harms brain development in children and raises blood pressure in adults. The EPA sets an action level, not a health goal above zero.
- **Atrazine** — A widely used agricultural herbicide that reaches water through runoff. Long-term exposure above the federal limit can affect the cardiovascular and reproductive systems.

## 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.
