Legal limits. Health goals. They're not always the same. See what the EPA actually has on record for your town.
"In compliance" means your water stays under federal legal limits. EPA also sets health goals, and the two aren't always the same number. That gap is the whole reason this site exists.
Start by finding out what's actually in your water. Then build from the foundation up: protect the house, upgrade what you drink, and add the hydrogen experience that fits your life.
Tap Score home water test · Essential City Water Test
Don't guess about your water. Public records describe your water system; a home test shows what's in the water at your own faucet. It doesn't diagnose anything.

In an industry built on fake sludge demos and "removes 100%" lies, we do the opposite.
Every report is built from EPA public-water data, including SDWIS compliance records, UCMR 5 monitoring and lead data where available. We link the source. No invented numbers.
We say a product removes something only if it holds the NSF certification for it. If it just reduces, we say reduces.
Salt-free conditioning stops scale — it doesn't remove chemicals. We'll never blur that line to make a sale.
Federal drinking-water standards vary by contaminant and change over time. We show EPA's legal limit and its health goal side by side, so you can see the gap.
