What the violations mean

Stage 1 Disinfection Byproducts Rule

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

Groundwater Rule

1 incident

The system did not complete a treatment step or action that the Groundwater Rule requires (a treatment technique violation).

The utility had to notify customers about this violation.

Where the water comes from

Middletown PWS draws water from 2 wells.

Annual water quality report

Middletown 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.

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 Middletown PWS for a copy.

Find a posted report with EPA's Consumer Confidence Report search

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 Missouri.
