Metropolitan Bus Depots – Environmental Compliance and Investigations

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.

Proof in the Soil: PSI and Screening for a Former Sawmill

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.

Fresh Lease, Clean Start: Baseline Check at a Busy Brisbane Logistics Hub

iEnvi completed a targeted, construction‑friendly Baseline Contamination Investigation at a large southern Brisbane warehouse and logistics facility to provide a defensible contamination snapshot for lease handover. The program combined desktop records review, GPR service clearing, targeted drilling (8 locations to ~8 m), 16 primary soil samples plus QA/QC for TRH, BTEXN, PAHs, metals and asbestos, and a Baseline Contamination Report signed by a CEnvP Site Contamination specialist.

From an EPA Clean-Up Notice to a Clear Path Forward

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.

Landfill Gas Assessment — Bus Depot, Albion VIC

Targeted landfill gas and groundwater assessment at an operating bus depot adjacent to two closed municipal landfills. No methane detected; EPA Victoria action levels not exceeded. Planning condition satisfied — no further LFG controls recommended.

Building Confidently on a Closed Landfill: Gas Risk Assessment and a practical CEMP

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.
