Denver Water collected about 63,000 water samples and conducted about 145,000 tests last year to ensure the water we deliver to 1.5 million people is clean and safe.
Those samples and tests are part of a year-round effort regulated by the Environmental Protection Agency and the Colorado Department of Public Health and Environment.
Denver Water’s 2025 Water Quality Report shows that your drinking water is safe and meets — or goes above and beyond — requirements set by the EPA and state health department.
The Spanish version will be available by June 1.
The report also contains important information about the source and quality of your drinking water, including data from the dozens of sites we monitor across our collection system.
