Last year, Denver Water collected more than 58,000 water samples and conducted about 128,000 tests.

Those samples and tests are part of a year-round effort monitored by the Environmental Protection Agency and the Colorado Department of Public Health and Environment.

Denver Water’s 2026 Water Quality Report 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.
