What’s in your tap water?

Every community water system in the U.S. is required to test its water and publish the results once a year. The problem is that those reports are buried, written for regulators, and easy to misread. So most people never look — and end up either worrying for no reason or buying a filter they don’t actually need.

Surprisingly, water can meet every federal legal limit and still contain things you want to filter. The legal limit and the health-based guideline often aren’t the same number, and the gap between them is where most of the real decisions live — things like lead from older pipes, PFAS “forever chemicals,” or the byproducts of disinfection. That’s not a reason to panic. It’s a reason to know what’s actually in the water at your address, instead of guessing from a headline.

That’s what this report is for. Enter your ZIP code and I’ll pull your utility’s latest results, flag anything sitting above health guidelines, and send you a plain-English breakdown of which contaminants — if any — are worth filtering, and the filter types that actually remove each one. It’s free, it takes about a minute, and there’s no jargon. I read these reports for a living; this is the version I’d want my own family to have.
