Leadwood

 

EWG's drinking water quality report shows results of tests conducted by the water utility and provided to the Environmental Working Group by the Missouri Department of Natural Resources - Public Drinking Water Program, as well as information from the U.S. EPA Enforcement and Compliance History database (ECHO). For the latest quarter assessed by the EPA (July 2018 - September 2018), tap water provided by this water utility was in serious violation federal health-based drinking water standards.

    Includes 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.

  • Bromodichloromethane

    cancer

    Bromodichloromethane, one of the total trihalomethanes (TTHMs), is formed when chlorine or other disinfectants are used to treat drinking water. Bromodichloromethane 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 bromodichloromethane in excess of health guideline

    The health guideline of 0.06 ppb for bromodichloromethane was proposed in 2018 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.

  • Radiological contaminants

    cancer

    This utility detected Radium, combined (-226 & -228), Radium-226, Radium-228 & Uranium.

    Radiological contaminants leach into water from certain minerals and from mining. Drinking water contamination with radioactive substances increases the risk of cancer and may harm fetal development.

  • Total trihalomethanes (TTHMs)

    cancer

    Trihalomethanes are cancer-causing contaminants that form during water treatment with chlorine and other disinfectants. The total trihalomethanes group includes four chemicals: chloroform, bromodichloromethane, dibromochloromethane and bromoform.
