Overview of a multi‑site sediment and soil remediation programme in Southern China (from 2012). Remediation combined delineation, in‑the‑dry excavation, solidification/stabilisation and beneficial reuse of treated material as engineered fill.
Practical environmental and regulatory advice provided during a NSW Government drainage dam construction project where impacted fill, asbestos and waste tyres were exposed on Crown Land. Advice focused on safe legal waste management, maintaining construction progress and proposing a long‑term Environmental Management Plan.
Urgent PSI (Phase 1) for an oil depot in Bowen, QLD: fieldwork started within three days to assess above‑ground tanks and diesel‑impacted soil, clarify leasing liabilities and support contract negotiation after an oil company acquisition.
Practical, cost‑conscious remediation and long‑term management of petroleum contamination at Council depots using a monitored natural attenuation (MNA)‑led strategy supported by targeted product removal, hydrogeological testing and fate‑and‑transport modelling.
Pilot-scale agricultural soil remediation in Gansu/Baiyin addressing Hg, As and Cd in root-zone soils. Combined excavation, mobile Matrix Enhanced Treatment System (METS) soil washing and targeted soil amendments to restore agricultural use and manage human health risk.
