Water Quality Laboratory
The city of Thornton Water Quality laboratory is charged with ensuring that the city's drinking water meets all state and federal drinking water regulations. Thornton has a qualified staff of water utility professionals that understand the importance a water supply plays in the overall quality of life for its community. They are dedicated to providing customers with the best quality of water that is possible. The water quality laboratory provides water sampling, monitoring and testing using approved procedures and methods in accordance with all regulatory requirements.
Treated water is collected and analyzed weekly at both Wes Brown and Thornton Treatment Plants and in the city of Thornton water distribution system. Raw water sources are also sampled and closely monitored to protect the quality of Thornton's drinking water. And, in addition to providing safe drinking water for Thornton's customers, the laboratory prepares and distributes an annual Water Quality Consumer Confidence Report and investigates water complaints.
