iEnvi characterised approximately 7,000 m³ of imported soil at a northern Adelaide development, classified it as Waste Derived Fill under SA EPA guidance and enabled reuse on site, reducing landfill, cost and development risk.
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.
Targeted landfill gas and groundwater assessment at an operating bus depot adjacent to two closed municipal landfills in Melbourne’s western suburbs. No methane detected and EPA Victoria action levels not exceeded. Planning condition satisfied with no further LFG controls recommended.
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 an asbestos- and contaminant-focused soil classification at an industrial chemical site in Melbourne, providing a compliant, cost-effective pathway for excavation and construction of a flammable goods storage area.
iEnvi investigated asbestos‑impacted soil and groundwater at an industrial site in northern Melbourne (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.
iEnvi provided site sampling, waste classification and VENM assessment for a state road agency during road remediation works in the NSW Central Tablelands, enabling compliant reuse and reducing disposal costs while keeping the project on schedule.
iEnvi completed an in‑situ waste classification and Excavated Natural Material (ENM) assessment for a Southern Highlands council road upgrade. Of 20 samples collected at 30 m intervals, 17 met ENM criteria, two were restricted solid waste and one was hazardous — enabling reuse of most material and avoiding excavation‑stage delays.
iEnvi reviewed environmental authority compliance, groundwater trends and leachate influence at five council-operated landfill sites north of Brisbane, providing statistical analysis, hydrogeological interpretation and targeted risk‑management recommendations.
Targeted soil investigations and in‑situ waste classifications were completed for trenches for NBN infrastructure across recreational properties in Brisbane. Findings identified localised contamination and supported CEMP recommendations under the General Environmental Duty.
