Annual Water Quality Reports

DC Water's Annual Water Quality Report details the outstanding quality of your drinking water.  Our test results demonstrate that your drinking water surpasses the water quality standards established by the U.S. Environmental Protection Agency (EPA). 

Over the course of the year, our water monitoring program tested more than 40,000 samples taken from a variety of sources across the District – more than required – to ensure that the water we deliver to local homes and businesses is clean and reliable.
