When a PSI is not enough: Detailed Site Investigation in Australia
When a PSI cannot close contamination questions, a DSI is required. NEPM Schedule B2 purpose, SAQP, CSM refinement, media and state practice.

iEnvi provided an independent asbestos source assessment and post-removal clearance at a greenfield development in south-west Sydney. 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.
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.
How a targeted investigation, waste classification testing and a pragmatic remediation strategy closed data gaps for asbestos‑contaminated imported fill in north‑west Sydney — turning a NSW EPA Clean‑Up Notice into a compliant, cost‑efficient remediation pathway.
Practical groundwater monitoring that confirms monitored natural attenuation, meets regulator expectations, and supports a safe transition from quarterly to biannual sampling with clear triggers and contingency planning.
Targeted, NEPM‑aligned due diligence (PSI + simple tenant lines of enquiry) to give fast, proportionate assurance for acquisition and staged redevelopment of an industrial site in South Australia — reserving intrusive investigation for clearly observed triggers.
How a lean, risk‑focused contaminated‑land approach gave a community sports club a construction‑ready landfill gas assessment and a practical Construction Environmental Management Plan (CEMP) so the clubhouse could be built safely, on time and on budget.
iEnvi completed a Baseline Environmental Condition Investigation (BECI) at an established western Melbourne bus depot to meet Department of Transport & Planning requirements. Targeted soil and groundwater testing (10 soil bores and monitoring wells) found no significant contamination; a Fuel System Operating Plan (FSOP) was recommended and reporting provided regulator‑defensible documentation under Victoria’s Environment Protection Act 2017.
