Vera Water and Power began full-time chlorination of the water system on October 1, 2013, after exceeding the allowable number of failed non-harmful total coliform samples. Non-harmful total coliform occurs naturally in our environment. After attempts to eliminate this problem, Vera was unable to isolate and eliminate the source of the problem.
The Washington State Department of Health issued a mandatory chlorination order for our system due to these failed samples.
Vera uses a disinfection system for its water, which is cleansed using calcium hypochlorite tablets. Disinfection begins at Vera’s well sites, allowing for the required contact time while water is flowing through our distribution system.
The risk with chlorination depends on the type of exposure and quantities taken in. Chlorine is a known carcinogen, but is more harmful in gas form and when used with surface water sources. You are exposed to chlorine in swimming pools, some pharmaceuticals, household cleaners, and public drinking water throughout the region and nation.
The traditional way to remove chlorine from your drinking water is to fill a pitcher and leave it uncovered in your refrigerator for 24 hours. By doing so, the chlorine will dissipate. Another method of removing chlorine is to use a carbon-based filter, either for one point of use or the entire house. For example, you can add filters to your kitchen sink, refrigerator or shower head.
Vera Water and Power, like most other large water systems in Washington, chlorinates full time. We are required to hold a minimum of .2 mg/l free chlorine residual in the entire distribution system. Vera continues to meet the Department of Health requirements and the Washington Administrative Codes.
