Think your land might be contaminated? Six signs worth checking

Most contamination is invisible from the surface — but a site almost always leaves clues. Before you buy, develop or dig, run through this checklist.

• The site's past lives. Former service stations, factories, dry cleaners, market gardens and filled land are among Victoria's most common contamination sources. Old aerial photos and historical titles tell you a lot.
• Suspicious fill. Building rubble, ash, slag or cement-sheet fragments in the soil mean uncontrolled fill — and uncontrolled fill means unknowns.
• Staining and odours. Dark hydrocarbon staining, or chemical and fuel smells — especially after rain or during excavation — are classic red flags.
• Stressed vegetation. Bare patches and plants that struggle for no obvious reason can point to what's underneath.
• Leftover infrastructure. Vent pipes, fill points, old tanks, pits and bores indicate underground storage you can't see.
• Paperwork flags. An Environmental Audit Overlay in the planning scheme, EPA notices, or gaps in the site's history all warrant a closer look.

None of these prove contamination — and their absence doesn't rule it out. The only way to know is targeted sampling. A Preliminary Site Investigation is fast and inexpensive compared to discovering a problem after you've settled or started works.

Found contamination? Why it doesn't have to kill your deal

It's the phone call every developer dreads: the assessment came back positive. But here's what decades of contaminated-land work teaches you — contamination rarely kills deals. Uncertainty does.

It's a cost item, not a stop sign

The vast majority of contaminated sites in Victoria are redeveloped successfully. Once contamination is characterised, it becomes what every other site issue is — a scoped cost with a timeline.

The rules work in your favour

Victoria's framework is risk-based: land needs to be made suitable for its intended use, not returned to pristine condition. A warehouse doesn't need the same outcome as a childcare centre — and your remediation strategy and budget should reflect that.

Early knowledge is negotiating power

Contamination discovered during due diligence is leverage — price adjustments, vendor contributions, extended settlements. Contamination discovered after settlement is your problem alone. The order matters more than the dirt.

Put real numbers in the feasibility

With early investigation, waste classifications and remediation scope become line items in your feasibility instead of blowouts halfway through civil works.

Deals die from unknowns. A clear, costed pathway keeps yours alive — and your development dreams with it.

Dealing with contamination: a straight-talking playbook

You've confirmed contamination on your site — what now? Four steps separate sites that get unlocked from sites that stall.

1. Get qualified help — early

This is not a do-it-yourself problem. You want senior consultants with deep EPA Victoria experience, established auditor relationships and a track record on sites like yours — involved before decisions get expensive. One accountable point of contact beats a chain of subcontractors.

2. Investigate once, properly

Cheap, thin investigations get repeated — that's how sites end up assessed three times. A well-designed preliminary and detailed site investigation answers the questions that matter the first time.

3. Plan remediation around your end use

A pragmatic Remediation Action Plan matches the method to your land use and program — reuse and containment where appropriate, not reflexive dig-and-dump. This is routinely a six-figure difference.

4. Validate and document

Validation reporting and clearance documentation are what regulators, auditors, financiers and future buyers rely on. Done properly, your problem stays solved.

Handled this way, contamination becomes a line item with a date and a cost — not a crisis.
