Take a moment to review our Water Quality Reports and other publications.
Exceeding Federal Regulations
Federal rules require that we test our water supply for more than 80 regulated contaminants and more than 50 unregulated chemicals, even if they do not exist in our water.
We take weekly samples from our water system to check for bacteria and chlorine residuals. Washington State Department of Health (DOH) rules also require us to take 150 samples per month; however we routinely take more than 220.
We also sample our water supply for other microscopic organisms such as giardia and cryptosporidium. Samples taken during the past four years indicate low levels of cryptosporidium and coliform bacteria in our protected Green River water supply. In fact, the bacteria level found is far below the level allowed for unfiltered water systems.
DOH inspects our operations annually and suggests ways to improve. Reliable operation and treatment are always their most critical concern. Our water must meet or exceed the highest standard or we will not send it to you.
