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 Brisbane’s inner east prior to construction of a sensitive-use facility found concentrations below regulatory assessment criteria for human health and ecological receptors. Soil was assessed as low risk, with reuse options available 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.
iEnvi supervised a 2019 resource-recovery program to reuse road asphalt millings as engineering fill for new sports fields. About 19,755 tonnes from 56 roads were reused under Recovered Aggregate Order requirements and assessed suitable for public open-space use.
OEMP for an auto vehicle storage and container-packing yard in northern Melbourne, VIC. Practical controls for fire, noise, air, soil and stormwater risk, aligned with AS 1940 recommendations and Sustainability Victoria guidance.
A case study of a limited pre‑purchase soil investigation at an open car park in western Sydney. The investigation identified historical fill with asbestos‑containing material, minor hydrocarbon impacts in saturated soils, existing groundwater bores and potential groundwater inflow to a proposed excavation. Practical risk management and next steps are summarised for developers and buyers.
Annual asbestos inspection of an electrical control room at a western NSW coal mine found asbestos-containing material in good condition. iEnvi managed a local contractor, reviewed sampling results and provided practical compliance recommendations.
Preliminary site investigations at two properties in northern Adelaide identified one former landfill (development unviable) and one suitable site, informing a developer’s decision on 50- and 70-lot townhouse villages.
Baseline environmental investigation for lease renewal of a petrol station in western Sydney, NSW. Two bores and two additional monitoring wells installed, groundwater and soil vapour assessed, with low residual risk and no duty to report under NSW CLM Act Section 105.
Low‑flow groundwater monitoring was completed at a decommissioned underground petroleum storage site at a ski lodge in the NSW alpine region. Results identified no ecological or human‑health groundwater risk, with recommendations provided for property transactions and regulatory compliance.
