Audit X-ray Victoria

For contaminated-land consultants and due-diligence teams

What do the EPA audits on and around this site actually say?

Audit X-ray reads the EPA Victoria environmental audits, 53V risk audits and PRSAs on a property and within 500 m, joins them with the Priority Sites Register and GQRUZ, and puts the answer on one screen: conditions, groundwater restrictions, vapour and capping controls, solvent plumes and their sources. Every fact links to the PDF page it came from.

Short answer

Chlorinated solvents in groundwater come from this site and extend off site to the south-west C p.9 A p.68. The 2020 statement sets 8 binding conditions: keep the cap, run the EMP and GQMP, do not use groundwater without testing, and do a new audit before any basement C p.8 C p.9.

On this land
  • 0008005833 Statement of environmental audit, 2020. Suitable for commercial and industrial land uses C p.8. 8 binding conditions.
  • The statement says: "Groundwater is polluted with Site-sourced chlorinated hydrocarbons which extend off-Site" C p.9. The plume runs south-west. Its modelled furthest extent is 76 m in about 41 years, measured from a well in the south-west of the site A p.68.
  • The groundwater plan names a possible second solvent source at a well about 100 m south-west, on Wanrua Street C p.87.

Mapped over this land
  • 0008005969 Environmental audit statement, 2024. The register maps it over 99.1% of this parcel. The statement itself names 17 Chandos Street, Lot 2 PS802507 C p.5, and its site plan puts Lot 1 (this parcel) outside the audit site C p.12. So its findings belong to Lot 2, to the south.
  • For Lot 2 it finds a site-sourced TCE plume going off site to the south, predicted to reach 150 to 160 m from the southern boundary in 70 years A p.52. 12 recommendations, including a permanent vapour barrier and no groundwater use C p.9.

Neighbours
  • 0008005308 Statement, 2020, adjoining to the south (Lot 4 PS802507). 5 binding conditions. Chlorinated solvents exceed criteria; the auditor calls them regional C p.10. Its findings belong to that lot.
Priority Sites Register
  • None on the parcel.
  • EAN-00010972 17 Chandos Street, 34 m S: former chemical storage facility, requires ongoing management. Same address as the 2024 statement above.

Bulk layer: suburb solvent screen

Every land audit in Moorabbin, Braeside, Highett and 8 adjacent suburbs, read in one unattended run. The map and table show the 30 audits that report chlorinated solvents in groundwater. Click a strength or source label to see the quote behind it.

Strength

Source

Grey dots: screened audits with no chlorinated finding in groundwater. Positions are EPA register points; one misplaced point is not drawn.

"Below criteria" needs a quote saying so. No audit in this set has one, so none show that label.

How much to trust this

The checks below were done by independent AI reviewers against the source PDFs, one acting as a contaminated-land consultant and one as a developer's due-diligence lead. No human audit yet: no consultant or auditor has checked these reports.

0invented conditions
  • 2 blind pilots of 10 addresses each. The reviewer picked the addresses.
  • Every finding links to its source page, so a consultant can verify each one in seconds.
  • Full-read check: the statement or summary pages and Part A findings and conclusions of all 6 audits the register places on these three parcels were read page by page. Of 25 summary claims checked, 17 held as written and 8 needed a correction or caveat, now shown above. The largest: the 2024 statement mapped over 328 Bay Rd names the lot next door.

Known limits

  • Register points and parcels. Some audits are a point, not a boundary. Matching uses distance and the address or title stated in the document, and conflicts are shown (see 328 Bay Rd).
  • Long documents are partly read. For every audit on the parcel, all statement pages and the Part A findings and conclusions are read. Other pages of long reports are not. Each report shows "pages read X of Y".
  • The register map can be wrong. At 328 Bay Rd the register maps a 2024 statement over the parcel, but the statement names the lot next door. The report shows both.

What a pilot looks like

You choose the sites. You get the same one-screen report as above for each one, with per-audit detail, page links and "pages read X of Y" for every document.

What this does not do

  • No historical titles, aerial photographs, business directories or site walkover.
  • It does not replace a preliminary site investigation (PSI).
  • The consultant signs off. The report helps you read the EPA register and is not advice.
