The Environmental Protection Agency requires community water systems to deliver a Consumer Confidence Report, also known as an annual drinking water quality report, to their customers. These reports provide customers information about their local drinking water. This includes raw water systems and drinking water systems, lead and copper projects, and regulated contaminants. Denver Water Tests and treats the water that is delivered to our water mains. As a Distributor for Denver Water, we have provided the Water Quality Reports provided by Denver Water below.
