About Tap & Air
Public data about your water and air exists, but it is scattered across federal databases and dense annual reports. We put it on one page per city.
Tap & Air turns EPA drinking water records, nationwide PFAS sampling, county radon zones and hardness data into a plain-English report for each large US city, with practical next steps for renters and homeowners.
We are not a utility, a lab or a government agency, and we do not sell water treatment equipment ourselves. Where a product or an installer genuinely helps, we link to one, and we may be paid for that. The data and the advice come first; read how in our methodology and disclosure.
