Recent peer-reviewed research from CSIRO and the SA EPA has tracked contamination in South Australian dolphins over three decades. The data reveals a downward trend in total PFAS concentrations across the Adelaide Dolphin Sanctuary and Port River Estuary. This drop in PFOS valida
A 261-page government report has been labelled a “fairy tale” by Australia’s leading ecological scientists. The Biodiversity Council has strongly condemned the Australian Government’s first progress report to the United Nations under the Global Biodiversity Framework. While the g
🔋 Spent carbon from PFAS groundwater treatment at contaminated sites may soon become a useful resource for battery manufacturing. For Australian projects managing PFAS in groundwater, pump and treat systems using granular activated carbon are standard practice. However, the spent
Every smartphone in the community is now an extension of the environmental regulator’s monitoring network. A local resident in Victoria recently filmed a truck dumping over 1,000 litres of contaminated construction and demolition soil on a cleared residential block in Ashwood. Th
A 94 per cent reduction in groundwater remediation liability. A newly published technical case study demonstrates how PFAS forensic source differentiation can reduce a landowner’s cleanup footprint. At a bulk petroleum storage facility, consultants used chemical fingerprinting to
iEnvi provided an independent asbestos source assessment and post‑removal clearance at a greenfield development in Catherine Field. The assessment determined the fragment originated from a historic stockpile, verification testing returned no asbestos detected, and the site was cleared to progress with development.
iEnvi characterised ~7,000 m3 of imported soil at Angle Vale (SA), classified it as Waste Derived Fill under SA EPA guidance and enabled reuse on site — reducing landfill, cost and development risk.
iEnvi supported a Tier 1 contractor to deliver NBN trenching and pit works across Brisbane Airport precincts, managing PFAS and asbestos risk, enabling in‑situ waste classification and immediate backfill to meet Commonwealth safety requirements and avoid costly hazardous disposals.
Practical environmental investigations and compliance audits across four Melbourne bus depots established a defensible baseline, identified localised hydrocarbon impacts near refuelling areas, confirmed no landfill‑gas risk from adjacent closed tips, and delivered reporting and management measures to meet Victorian regulatory expectations.
A concise, defensible Preliminary Site Investigation (PSI) and targeted soil screening at a former regional Queensland sawmill clarified contamination risk (timber-treatment residues, unknown fill, petroleum), updated the conceptual site model and set clear triggers for any further DSI or groundwater work — supporting sale, planning and due diligence.
