Environmental risk, made legible

We translate ~25 fragmented federal databases into one coherent, plainly-worded picture of what's in your water, soil, air, and walls.

Enter an address

Any US residential address. We geocode it instantly and match it to the right water utility, census tract, and regulatory jurisdictions.

We query 25+ databases

EPA drinking water violations, FEMA flood zones, USGS radon maps, Superfund proximity, county assessor build year, and more — in seconds.

Deterministic risk engine

Hard-coded rules convert raw data into risk levels. No AI guesses your risk — every flag traces to a specific data point and source.

Fully sourced report

Every finding cites its exact source — EPA, ATSDR, HUD, CDC — with verbatim quotes. You see the evidence, not just the conclusion.

Nine categories. One address.

Each category is assessed independently using data specific to your address.
