What’s actually coming out of your tap? Enter your ZIP code and find out — free, in about 60 seconds.
Every public water utility in America is required to test its water and report what it finds. Almost nobody ever reads those reports. We turn that public data — EPA compliance records and the Environmental Working Group’s national tap water database — into a plain-English answer: what’s in your water, and whether it’s worth filtering.

What we look for
Lead
Enters water from older service lines and home plumbing — no safe level for children. Testing is the only way to know.
PFAS “forever chemicals”
Now federally regulated at 4 parts per trillion. Many utilities are still years away from full treatment.
Chlorine byproducts
Disinfection keeps water safe to deliver, but byproducts like THMs are linked to long-term health risks.
Nitrates
From fertilizer and runoff — a special concern for private wells and homes near farmland.
Arsenic & heavy metals
Naturally occurring in some regions’ groundwater; invisible, tasteless, and fully filterable.
Hardness & scale
Not a health risk — but it shortens the life of every appliance that touches water in your home.
