Willawong Landfill Gas Preliminary Site Investigation and Risk Assessment
iEnvi landfill gas PSI and risk assessment at Willawong QLD for a warehouse DA next to a closed landfill and waste transfer station. No detectable methane; indicative CS1.
Asbestos Source Assessment and Clearance for a Development Site, Catherine Field
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.
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 Quarterly to Biannual: Groundwater Monitoring that Keeps Risk Low
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.
Confident Acquisition Backed by Targeted Environmental Checks
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.
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.
Compliance investigation and cost‑effective remediation of asbestos‑impacted soil — Coolaroo industrial site (VIC)
iEnvi investigated asbestos‑impacted soil and groundwater at an industrial site in Coolaroo (VIC). Bonded asbestos in stockpiled soil was removed by hand‑picking (emu‑picking) and the remaining material verified for reuse as clean fill, avoiding costly landfill disposal while meeting EPA Victoria obligations under the General Environmental Duty.
Hexavalent Chromium Groundwater and Soil Remediation – Steel Processing
Remediation program for Cr6+ impacted soils and fractured-basalt groundwater at a long‑running steel processing facility. Summary of contamination, in‑situ treatment techniques trialled, pilot results and commercial considerations for redevelopment and liability management.
