Denver Water collected about 63,000 water samples and conducted about 145,000 tests last year to ensure the water delivered to 1.5 million people in their service area is clean and safe.
Those samples and tests are part of a year-round effort regulated by the Environmental Protection Agency (EPA) and the Colorado Department of Public Health and Environment.
Denver Water’s 2025 Water Quality Report(opens in new window)(opens in new window)(opens in new window) shows that your drinking water is safe and meets requirements set by the EPA and state health department.
The report also contains important information about the source and quality of your drinking water, including data from the dozens of sites monitored across their collection system.
