How to read a water report
Regulatory limits
The EPA sets legal limits (like MCLs) that public water systems must meet. When we show one, it's always labeled as a legal limit.
Health guidelines
Some organizations publish stricter, non-regulatory health guidelines. They're useful context — but they are not legal limits, and we never present them as such.
Context, not fear
City data describes the public water supply — not your exact faucet. We show results within standards alongside the ones worth a conversation. Informative, not frightening.
