Mount Charleston Water Company

 

EWG's drinking water quality report shows results of tests conducted by the water utility and provided to the Environmental Working Group by the Nevada Division of Environmental Protection, 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.

contaminants detected above health guidelines

other detected contaminants

    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.

  • Radiological contaminants

    cancer

    This utility detected Radon, 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.

    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.
