EWG's Tap Water Database

Donate

Klondike Independent School District

 

EWG's drinking water quality report shows results of tests conducted by the water utility and provided to the Environmental Working Group by the Texas Commission on Environmental Quality , as well as information from the U.S. EPA Enforcement and Compliance History database (ECHO). For the latest quarter assessed by the EPA (July 2017 - September 2017), tap water provided by this water utility was in serious violation federal health-based drinking water standards.

other detected contaminants

    Includes chemicals detected in 2015 for which annual utility averages exceeded the federal Maximum Contaminant Level (MCL); chemicals detected in 2015 for which annual utility averages exceeded an EWG-selected health guideline established by a federal or state public health authority; radiological contaminants detected between 2010 and 2015.

  • Bromoform

    cancer

    Bromoform, one of the total trihalomethanes (TTHMs), is formed when chlorine or other disinfectants are used to treat drinking water. Bromoform and other disinfection byproducts increase the risk of cancer and may cause problems during pregnancy. Click here to read more about disinfection byproducts.

    Health risks of bromoform in excess of health guideline

    The health guideline of 5 ppb for bromoform was defined by the California Office of Environmental Health Hazard Assessment as a one-in-a-million lifetime risk of cancer. Values greater than one-in-a-million cancer risk level can result in increased cancer cases above one in a million people.
