UPSS Abandonment In‑situ via Foam Filling — Hervey Bay, QLD

UPSS abandonment anddecommissioning underground fuel tank QLD

iEnvi managed in‑situ abandonment of three underground storage tanks at a restaurant in Hervey Bay, 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 (EMR).

Groundwater and Hydrogeological Investigation of Five Landfills — north of Brisbane (QLD)

hydrogeology water contamination

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 Investigation and Insitu Waste Classification, Brisbane, QLD

targeted soil investigation nbn

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.

Preliminary Site Investigations for Potential Acquisition, VIC and WA

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.

UPSS and Detailed Site Investigation for a Rural Service Station in Far North Queensland

core-sample-upss

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.

Law firm engagement for Preliminary and Detailed Site Investigation of Former Service Station, Inner Sydney NSW

UPSS contamination site investigation

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.

Preliminary Site Investigation of a mechanic workshop for finance approval, Wynnum QLD

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.

Innovative and cost-effective soil investigation, Sydney NSW

park recreation site investigation

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.

Cost‑Efficient Remediation for Hydrocarbon Contamination — Newcastle & Wollongong, NSW

Contaminated Sites Evaluation

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.
