We’ve put a lot of effort into creating the following infographic. It’s titled The Current State Of U.S. Public Tap Water.
The graphic tells you what tap water contaminants can be found in which regions of our country. Furthermore, it lists all harmful substances that were found in concentrations exceeding legal limits and how they can affect your health.
All data was gathered from the freeĀ Tap Water Database of the Environmental Working Group (EWG). The database provides more than 30 million test results for nearly 50,000 water utilities in all 50 states of the U.S. and Washington, D.C.
Water samples were tested for 502 different contaminants. A total of 267 were found. More than 160 of them are currently unregulated by a nationwide drinking water standard.
