Purpose
MyWaterFacts helps homeowners, renters, movers, and home buyers understand local water. The goal is not to replace a utility, regulator, certified lab, plumber, or water-treatment professional. The goal is to make public water information easier to find and understand.
How Water Profiles are built
Each Water Profile combines public utility information, annual water quality reports, source-water context, water hardness information where available, and practical homeowner guidance. Profiles should show what is known, what is estimated, and what remains uncertain.
Water Facts Score
The Water Facts Score measures data availability and usefulness. It is not a water safety rating. A high score means public information is easier to find, more current, and more complete for that location.
| Range | Meaning |
|---|---|
| 90–100 | Excellent data availability |
| 75–89 | Strong data availability |
| 60–74 | Moderate data availability |
| Below 60 | Limited data availability |
Confidence levels
Profiles use confidence labels to avoid fake precision. High confidence means direct official sources are available. Medium confidence means public information exists but some fields require regional or secondary interpretation. Low confidence means the profile is a starting point only.
What MyWaterFacts cannot tell you
Public data does not test the water at your specific faucet. Plumbing, building age, service lines, private wells, treatment equipment, and provider boundaries can affect what reaches your tap.
