Ozark County Public Water Supply District 1
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 compliance with 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.
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.
How your levels compareThe State and National averages were calculated using the averages of the contaminant measurements for each utility in 2010-2015.
ppb = parts per billion.
