|---|---|---|---|
| Haloacetic acids (HAA9) | 27.51 ppb | 0.0600 ppb | β οΈ 458.5x above |
| Haloacetic acids (HAA5) | 29.67 ppb | 0.1000 ppb | β οΈ 296.7x above |
| Total trihalomethanes (TTHMs) | 37.00 ppb | 0.1500 ppb | β οΈ 246.7x above |
| Bromodichloromethane | 8.00 ppb | 0.0600 ppb | β οΈ 133.3x above |
| Bromochloroacetic acid | 2.37 ppb | 0.0200 ppb | β οΈ 118.3x above |
| Trichloroacetic acid | 11.23 ppb | 0.1000 ppb | β οΈ 112.3x above |

Haloacetic acids (HAA9)
The health guideline of 0.06 ppb for haloacetic acids (HAA9) was defined by EWG . This health guideline protects against cancer.
National Average: 23.70 ppb | Wyoming Average: 27.51 ppb
Haloacetic acids (HAA5)
The health guideline of 0.1 ppb for haloacetic acids (HAA5) was established. This health guideline protects against cancer.
National Average: 19.82 ppb | Wyoming Average: 29.67 ppb
Total trihalomethanes (TTHMs)
The health guideline of 0.15 ppb for trihalomethanes was defined by in a peer-reviewed scientific study by EWG and represents a one-in-one-million lifetime cancer risk level. as a draft public health goal, the level of drinking water contaminant that does not pose a significant health risk. This health guideline protects against cancer.
National Average: 29.06 ppb | Wyoming Average: 37.00 ppb
Bromodichloromethane
The health guideline of 0.06 ppb for bromodichloromethane was defined by the California Office of Environmental Health Hazard Assessment as a one-in-a-million lifetime risk of cancer. Values greater than one-in-a-million cancer risk level can result in increased cancer cases above one in a million people.
National Average: 5.89 ppb | Wyoming Average: 8.00 ppb
