Water Safety Indianapolis water supply is safe - Water provided by Citizens Energy Group meets the rigorous federal public health standards of the Safe Drinking Water Act. Citizens carefully monitors for a wide range of possible contaminants in both untreated water supply and its finished drinking water. - Citizens monitors for more than 100 possible contaminants in its water supply, including the chemicals of concern cited by EWG. Our water treatment process accounts for these types of contaminants. Citizens Energy Group continually reviews its water testing protocols to ensure they meet or exceed federal standards. The public health goals for contaminants cited in the EWG report are below standards set by the Safe Drinking Water Act - Some of the public health goals cited by EWG are not widely accepted in the scientific community. Also, having water utilities meet some of these public health goals would not be technically feasible without significant changes to our economy and associated regulations. For example, meeting some of the public health goals cited by EWG would require banning the use of certain agricultural chemicals. Citizens Energy Group is continually improving our water system - Since 2011 when we acquired the local water utility, Citizens has invested more than $250 million in the system to ensure water quality and system reliability. For example, we have added ultraviolet (UV) disinfection systems to all of our surface water treatment plants. The UV systems provide an extra level of protection against certain microorganisms getting into our water supply and potentially making people sick. Water safety is best achieved by preventing contamination of water supply sources - The nation's waterways are significantly cleaner than they were when the federal Clean Water Act was passed in 1972. These improvements are the result of billions of dollars of investments by local, state and federal governments, and water utilities. Here in Indianapolis, Citizens Energy Group is investing about $2 billion in the Diglndy Project, a 28-mile network of deep tunnels that will nearly eliminate sewer overflows to area waterways by the year 2025. While much progress has been made in cleaning up the nation's waterways, there is always room for improvement to ensure water safety. Sierra Club v. EPA 18cv3472 NDCA Tier 7 ED 002061 00065294-00001
