Enforcement actions

Colorado regulators took 3 formal enforcement actions against Sun Meadow Estates between 2012 and 2024. The most recent was a compliance order with a penalty in December 2024.

Date By Action Violations covered
Dec 30, 2024 Colorado Compliance order with a penalty 8 violations (3 health-based): Gross Alpha, Excl. Radon and U, Lead and Copper Rule
Mar 8, 2018 Colorado Compliance order (no penalty) 39 violations (39 health-based): Combined Uranium, Total Trihalomethanes (TTHMs)
Aug 24, 2012 Colorado Compliance order with a penalty 35 violations (35 health-based): Total Trihalomethanes (TTHMs), Combined Uranium

What the violations mean

Total Trihalomethanes (TTHMs)

22 incidents

Disinfection byproduct levels exceeded the federal limit

Long-term TTHM exposure may increase bladder cancer risk

Combined Uranium

7 incidents

Test results for Combined Uranium were above the federal limit (a maximum contaminant level violation).

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

Gross Alpha, Excl. Radon and U

6 incidents

Test results for Gross Alpha, Excl. Radon and U were above the federal limit (a maximum contaminant level violation).

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

Stage 1 Disinfection Byproducts Rule

1 incident

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

Where the water comes from

Sun Meadow Estates draws water from 2 wells.

Annual water quality report

Sun Meadow Estates 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 Sun Meadow Estates 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 Colorado.
