Property Scores — 08 of 08
Official EPA contaminated-site registers and industrial land-use history, combined into one per-address score. Free for any address in Australia.
The Problem
Old fuel depots, dry cleaners and factories leave legacies in soil and groundwater that outlast the buildings.
Each state EPA publishes its register differently, some as searchable maps, some barely at all. Nobody checks three systems for one address.
Registers list confirmed, notified sites. Plenty of historical industrial land never made the list.
Site contamination usually surfaces at the environmental assessment, deep into a purchase. Early screening is almost free by comparison.
Live Example
Live EPA records and industrial sites inside the 2 km screening radius — from warehouse-conversion territory to the leafy east.
Honest by Design
The difference between “the EPA has a record near this address” and “there is a fuel station nearby” matters enormously. Our responses never blur the two.
Where a register exists and returns nothing, that is also stated: checked, no hit. Absence of evidence is only meaningful when you know something was actually checked.
| Signal | Source | Coverage |
|---|---|---|
| Contaminated-site registers | State EPAs (live) | VIC, NSW, WA |
| Industrial proximity | Continental POI dataset | National |
How It Works
Two signal layers, and the response is explicit about which one applies.
We query the contaminated-land registers of Victoria, NSW and Western Australia live. A register site near the address is the strongest signal there is, and it dominates the score.
Nationwide, we measure proximity to the land uses that generate most contamination legacies: fuel stations, factories, dry cleaners and similar industrial points.
Signals decay with distance. A register site at 100 metres and one at 900 metres are very different findings, and the score reflects that.
The Register Sweep
A register record is official evidence; a nearby fuel station is only a labelled proxy — the same 500 m sweep reports each for exactly what it is.
queried live in VIC, NSW and WA — and every response says whether the register was hit, checked with no hit, or not available.

Data at Scale
Who It's For
That charming warehouse-conversion suburb had warehouses once. Screen the address before the soil becomes your problem.
Contamination findings can add remediation costs that kill a project. Screen candidate sites before committing to Phase 1 assessments.
Add a contamination screen to due-diligence reports, with the register status stated per state.
Property Scores
Each score uses open government data with transparent methodology. No black boxes.
