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.
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.
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.
Clear, practical guidance for site owners, developers and environmental managers on recognising a hydrocarbon sheen versus measurable LNAPL in groundwater, when a risk-based duty to notify regulators can be triggered in Australia, and how to manage next steps to reduce transaction, development and compliance risk.
iEnvi completed a Delineation Investigation (DI) at an aerosol and paint manufacturing site in northwest Sydney. The DI installed three groundwater monitoring wells, 13 soil bores and two stormwater points, collecting 8 groundwater, 39 soil and 2 stormwater samples. Findings showed minor soil hydrocarbons (one local exceedance), groundwater elevated dissolved metals likely related to background geochemistry, and isolated vapour-intrusion exceedances — prompting targeted sub‑slab vapour testing and further risk-management recommendations to meet NSW EPA expectations.
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.
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.
Case study: CEMP, ESCP and VMP prepared by iEnvi for a regional council to manage vegetation clearing, earthworks, acid sulfate soils, fauna risk and sediment during construction of a sports complex in South East Queensland.
