Cone Delfred Subdivision

 

EWG's drinking water quality report shows results of tests conducted by the water utility and provided to the Environmental Working Group by the Idaho Department of 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 2018 - September 2018), tap water provided by this water utility was in compliance with federal health-based drinking water standards.

    HEALTH GUIDELINE:
    0.4 ppb
    0.000573 ppb
    0.00740 ppb
    0.570 ppb
    The State and National averages were calculated using the averages of the contaminant measurements for each utility in 2015.
    ppb = parts per billion.

    Health risks of 1,2-dichloroethane in excess of health guideline

    The health guideline of 0.4 ppb for 1,2-dichloroethane was defined by the California Office of Environmental Health Hazard Assessment as a public health goal, the level of a drinking water contaminant that does not pose a significant health risk. This health guideline protects against cancer.

  • Radiological contaminants

    cancer

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

    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.

    Includes chemicals detected under the EPA's Unregulated Contaminant Monitoring Rule (UCMR 3) program in 2013 to 2015, for which annual utility averages were lower than an EWG-selected health guideline established by a federal or state public health authority.

  • Chromium (total)


    Chromium is a naturally occurring metal, but industrial uses can elevate its levels in water. One form, hexavalent chromium, causes cancer. Total chromium is not a good indicator of the amount of hexavalent chromium in drinking water.
