What the violations mean

Combined Radium (-226 and -228)

The utility had to notify customers about each of these violations.

Stage 1 Disinfection Byproducts Rule

2 incidents

The system did not meet a treatment requirement of the Stage 1 Disinfectants and Disinfection Byproducts Rule

Byproducts form when disinfectants react with natural material in water. Long-term exposure above federal limits may increase cancer risk

Revised Total Coliform Rule

1 incident

The system did not meet a requirement of the Revised Total Coliform Rule

Coliform and E. coli rules protect against bacteria in the distribution system

Where the water comes from

Bristol WSD draws water from 2 wells (1 of them for emergency, seasonal or other part-time use).

Annual water quality report

Bristol WSD must give its customers an annual water quality report (Consumer Confidence Report) by July 1, with the levels its tests found in the previous year.

Systems serving 500 or fewer people may meet the rule by telling customers the report is available on request, so you may need to ask Bristol WSD for a copy.

Testing your own water

To test the water at your tap, or a private well this record does not cover, use a laboratory certified for drinking water by Colorado.
