iEnvi’s 100 Contaminated Land Experts in 2022!
iEnvi expanded its network of independent contaminated‑land sub‑consultants in 2022 to improve local availability, technical depth and delivery flexibility for clients across Australia.
Project
Major NSW Infrastructure Project, Environmental Sampling and Waste Classification (Central Tablelands)
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.
Former Oyster Farm Investigation for Residential Development
Targeted soil assessment of a former oyster farm footprint identified low-risk PAH sources (asphalt fragments) rather than residual coal tar, resolving a data gap and enabling council approval for low-density residential development.
UPSS Abandonment In‑situ via Foam Filling, Wide Bay Region QLD
iEnvi managed in‑situ abandonment of three underground storage tanks at a commercial property in the Wide Bay region, QLD, using foam filling to avoid structural impacts. Work complied with AS4976‑2008 and included guidance on validation groundwater monitoring and UPSS completion to progress removal from the QLD Environmental Management Register.
Construction Environmental Management Plan for a Sports Complex, South East QLD
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.
Microbiologically Influenced Corrosion Preliminary Study — Mornington Peninsula VIC
A 2020 preliminary assessment by iEnvi identified microbiologically influenced corrosion (MIC) risk for planned pipeline works and staging areas on the Mornington Peninsula, recommending targeted metallurgical and microbiological follow-up to protect assets and reduce failure risk.
Waste Classification and ENM Assessment, Southern Highlands NSW
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.
Erosion Sediment Control Plan (ESCP), Mornington Peninsula, VIC
iEnvi updated the ESCP for a State Significant development in the Mornington Peninsula using MUSIC stormwater modelling and IECA-aligned erosion and sediment controls to reduce construction-phase sediment risk and support regulatory compliance.
Urgent Preliminary Site Investigations for M&A, Multiple Sites QLD, NSW, SA
iEnvi completed urgent preliminary site investigations at three metal fabrication sites (QLD, NSW, SA) for M&A due diligence, delivering PSI reports within one week and recommending targeted soil testing where moderate–high risks were identified.
Groundwater and Hydrogeological Investigation of Five Landfills — north of Brisbane (QLD)
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.
