What the violations mean
Stage 1 Disinfection Byproducts Rule
1 incidentThe 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
Where the water comes from
Pineville PWS draws water from 4 wells (2 of them for emergency, seasonal or other part-time use).
Annual water quality report
Pineville PWS 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.
Where the state allows it, systems serving fewer than 10,000 people may publish the report in a local newspaper or news site instead of mailing it, and must provide a copy on request.
