Managing Water Quality From Source to Tap

Your water’s journey starts as mountain snowpack and ends with the clean, great-tasting water that comes out of your tap.

As a part of our extensive testing program, each year we collect more than 35,000 samples and conduct nearly 70,000 water quality tests. These efforts continually confirm that your drinking water is safe and meets or exceeds federal and state requirements.

From its mountainous source to the treated purity at your tap, we take water quality very seriously.
