How often is my water tested?
In accordance with federal and state regulations, the water throughout the distribution system is tested once every three years. Over 700 samples are taken annually. The Washington Department of Health (DOH) allows us to monitor for some contaminants less than once per year because the concentrations of these contaminants do not change frequently. We take water samples throughout our service area and send them to independent testing laboratories. All test results are reported to the DOH. The District’s water quality meets all federal and state standards.
