Denver Water collects more than 35,000 water samples and conducts more than 70,000 tests every year to ensure the water we deliver to 1.4 million people is clean and safe.
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. Those agencies also require water providers to issue an annual report on water quality.
Denver Water’s 2019 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 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.
