Why We Have Great Water in El Dorado
Protecting Our Drinking Water
The superior quality of El Dorado Water Treatment Facility’s drinking water is the result of a combination of the proper operation of a multistage treatment facility and a laboratory that performs 2,500 monthly tests on samples taken during the treatment process and throughout the 123 miles of distribution system piping. El Dorado currently has 4 personnel that hold a Class IV Water Operator’s license, the state’s highest certification level. Water quality is monitored 24 hours a day, 365 days a year. Chemical dosages are scrutinized daily and sophisticated instrumentation keeps a close watch on water quality. Another aide in achieving great tasting water is the addition of powdered activated carbon (PAC). PAC absorbs many of the musty odors associated with surface water, and is then filtered out in the dual media filters.
Disinfection of the Distribution System
The Kansas Department of Health and Environment recommends all cities switch from chloramines to free chlorine for at least 1 week a year to thoroughly disinfect the distribution system. The type of chlorine normally in the water, chloramines, has no chlorine taste or odor, which most people prefer, but it is not as powerful a disinfectant as free chlorine. Most people notice the change in the taste of the water for about a week when we perform this recommended switch for a short time each year.
Algae Taste & Odor
Algae taste and odor are usually not a problem in El Dorado for two reasons. First, we have very clean, good quality source water in El Dorado Lake with low nutrient levels. Excessive nutrients lead to algae blooms. Second, for any algae blooms that have occurred, we have a powdered activated carbon treatment system that absorbs the taste and odors associated with algae. This system operates continuously to give us the best tasting water possible.
Water System Requirements Most public water systems deliver high quality drinking water that meets stringent federal and state standards to millions of Americans every day. Systems are required to test regularly for 90 contaminants (from Atrazine to Zinc) to make sure that no contaminant is present at levels, which may pose a risk to human health.
Reports Drinking water suppliers now provide reports, usually called consumer confidence reports (CCR's) or Water Quality Reports. These reports tell consumers where their drinking water comes from, what contaminants may be in it, and how they can protect it. Click here to see El Dorado's 2017 Water Quality Report.
Safe Drinking Water Act (SDWA) The SDWA, which celebrated its 30th anniversary in 2014, is the main federal law that ensures the quality of Americans' drinking water. Under SDWA, EPA sets standards for drinking water quality and oversees the states, localities, and water suppliers who implement those standards.
