Legal & disclosures
Transparency is part of the product, so our disclosures are written to be read — not buried. Each one below states the limit plainly and explains, in ordinary language, why it exists and what it means for you.
Disclosures
The four limits that govern everything we publish. Each is quoted verbatim, then explained in plain language.
This tool aggregates municipal engineering data and hardware certifications. It does not diagnose exposure risks, predict toxicological outcomes, or offer medical advice.
We report engineering measurements and hardware certifications — not health verdicts. Nothing here diagnoses exposure or predicts a toxicological outcome. For questions about your health, consult a licensed medical professional.
Utility data is aggregated at the water-system level and cannot account for plumbing-specific contamination such as legacy household lead service lines. A point-of-use lab test is the only way to verify contamination introduced by your home's plumbing.
Utility data describes the water as it leaves the system, not as it arrives at your faucet. Contamination introduced by your home’s own pipes — a legacy lead service line, for instance — is invisible to system-level records. A point-of-use lab test is the only way to see it.
The supplying utility for this address was resolved using a modeled radius (low confidence). Confirm the utility name printed on your water bill, and consider a physical Tap Score lab test for absolute certainty.
When an address resolves only to a modeled radius, the underlying map is uncertain — so we say so. Confirm the utility name on your water bill, and consider a lab test before acting on a low-confidence match.
Recommended hardware links are affiliate placements. Products are surfaced solely because they hold independently verified NSF/ANSI health certifications for the detected contaminants; commercial rankings never override objective scientific data.
Some hardware and lab-test links are affiliate placements, and we may earn a commission. Those links are clearly marked “Verified Partner,” and a product only appears after qualifying on the relevant NSF/ANSI health certification. Commercial ranking never reorders the science.
Terms of use
A plain-language summary. It describes how the service is meant to be used and does not replace formal terms.
WaterQualityLens is an informational tool. It aggregates public municipal water data and independent product certifications to help you understand your water and your filtration options. It is provided as is, for general information, and does not constitute professional, legal, or medical advice.
Privacy
A plain-language summary of how we treat your data.
The core lookup is designed to be used anonymously. You do not need an account to check an address, and we do not require you to create one to see your results.
