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.
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.
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 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 eastern Brisbane, QLD to support finance approval. Targeted soil sampling returned no detections of contaminants of concern, enabling the lender to approve the purchase. Practical ongoing management steps were provided 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.
