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.
iEnvi completed an Underground Petroleum Storage System (UPSS) integrity check and Detailed Site Investigation (DSI) at a service station with an attached dwelling in Far North Queensland. Soil sampling adjacent to former tanks, fuel lines and bowsers found evidence consistent with a fuel-line leak; iEnvi provided a staged investigation and cost estimate to support purchase negotiations and subsequent remediation works.
iEnvi completed a confidential PSI and UPSS investigation at a commercial inner-Sydney property to define hydrocarbon impacts to soil, groundwater and soil vapour, and to quantify the likely remediation and compliance implications if the site is converted to residential use.
iEnvi carried out a preliminary site investigation at a mechanic workshop in Wynnum, QLD to support finance approval. Potential contamination sources were inspected and targeted soil sampling returned no detections of contaminants of concern, enabling the lender to approve the purchase. Practical ongoing management steps were provided to the client to minimise future contamination risk.
iEnvi completed preliminary soil investigations at multiple inner‑Sydney parks in early 2019. Hydrocarbons were detected in shallow soil at two parks, and targeted leachate testing demonstrated the hydrocarbons were immobile, allowing playground upgrades to proceed without further remediation or environmental management plans.
Targeted soil sampling at three sites identified shallow hydrocarbon contamination at two locations. iEnvi recommended a cost‑efficient program combining a biological treatment additive (S200 OilGone) with excavation and encapsulation to reduce health, ecological and transaction risk.
Shallow soil testing at a residential site in Morningside prior to construction of a childcare centre found concentrations below regulatory assessment criteria for human health and ecological receptors. Soil was considered low risk and no further action was required. Reuse options may now be considered prior to offsite removal.
iEnvi completed a preliminary site investigation (PSI) and soil sampling for a Sydney property intended for residential redevelopment. A 253‑page technical report and site history review concluded the site is suitable for residential use and suitable to support a development application.
