Auburn Water Department

 

EWG's drinking water quality report shows results of tests conducted by the water utility and provided to the Environmental Working Group by the Indiana Department of Environmental Management, 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.
