See Environmental Risk Before It Costs You
Make Informed Decisions Before Risks Escalate
Environmental Services
Clear evidence that keeps approvals, budgets and programs on track.
Unidentified contamination can delay approvals, disrupt excavation and add unplanned disposal costs to your project. Geotesta investigates soil, groundwater, surface water and soil vapour to establish what’s actually present on site and what it means for your program. We then turn those findings into practical next steps, helping you manage environmental duties, remediation requirements and material movement with confidence at every stage.

Proven Across a Diverse Range of Projects
Environmental Due Diligence Assessment, Charlemont
A due diligence environmental assessment for a proposed aged-care redevelopment at Charlemont, confirming the site was suitable and unlikely to need further investigation.
UPSS Decommissioning and Validation, Mentone
When the EPA flagged an underground petroleum storage system at this Mentone service-station site, Geotesta investigated, decommissioned and removed the tanks, and validated the excavations — closing the EPA case and keeping the site operating.
