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.
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 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.
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.
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.
Summary of a targeted soil investigation that confirmed historical lead from a former rifle range on a proposed sports field site north of Brisbane and recommended a Long Term Environmental Management Plan to manage development risks.
iEnvi assessed a 1,800 m3 soil stockpile for an inner-west Sydney council to determine suitability for reuse. Targeted test pits and laboratory analysis showed the material generally met the Excavated Natural Material Order 2014 criteria but required processing and a Specific Resource Recovery Order/Exemption from the NSW EPA before reuse as bunding engineering fill.
Two coatings manufacturing sites in Victoria and Western Australia were assessed by iEnvi through preliminary site investigations (PSI) to identify contamination risks, regulatory implications and recommended next steps for acquisition decisions.
iEnvi prepared an Operational Environmental Management Plan (OEMP) and a Pollution Incident Response Management Plan (PIRMP) for a new regional brewery and onsite wastewater treatment plant. The plans incorporated the site’s EPL and local council Trade Waste Agreement to manage wastewater, odour, spills and regulatory obligations ahead of commissioning.
