EWG has just completed the update for their tap water database (2019) with the results being available to you by just going online and requesting the results for your zip code. When you input your zip code, it identifies your water supplier.
Note: Your zip code is a series of numbers that will identify or pinpoint your geographic location.
EWG in addition to the above has prepared the following information for download
In conclusion, no matter where you live and how you obtain your water go to the EWG site (https://www.ewg.org) and learn.
