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.
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 completed a 216‑page Preliminary Site Investigation and soil sampling program for a proposed Nepali place of worship in north‑western Sydney. The PSI found no evidence of contamination that would prevent the proposed use, and provides the documentation needed to support a Development Application where land history indicates only agricultural use.
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.
A concise case study of a limited pre‑purchase soil investigation at an open car‑park in Rosehill NSW. Investigation identified historical fill with asbestos‑containing material (ACM), minor TRH and PAH in saturated soils, existing groundwater bores, and potential groundwater inflow to a proposed excavation pit. 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.
iEnvi completed a 250‑page preliminary site investigation (PSI) and soil sampling program for a community group seeking development consent to use a western Sydney property as a place of worship. The investigation supported a successful development application.
Baseline environmental investigation for lease renewal of a petrol station in Granville NSW. Two bores and two additional monitoring wells installed, groundwater and soil vapour assessed — 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 in Perisher Valley. Results identified no ecological or human‑health groundwater risk; recommendations and compliance notes provided for property transactions in Snowy Mountains National Park.
