What you'll get
Three things, immediately.
Every flagged contaminant
Each substance EWG measured above its health-protective guideline — with the multiplier, the source category, and what removes it.
EWG vs. EPA gap, made obvious
Federal legal limits next to EWG's stricter health guidelines so you can see when your utility is in legal compliance but still posting concerning numbers.
The utility itself, plainly
Population served, primary source water, cities covered. No EPA jargon — written so a non-engineer can use it.
Reports are generated live from EWG's Tap Water Database the first time a ZIP is requested, then cached for 30 days. No account. No personal data stored unless you subscribe.
