iEnvi completed two fast-turnaround Preliminary Site Investigations (PSI) near Adelaide, SA. One site showed significant risk from past loam mining and fill and requires a larger investigation, remediation and auditor sign-off; the second was suitable for a 50‑lot subdivision after limited sampling.
The NSW Environmental Protection Agency (EPA) updated the Contaminated Land Management Compliance Statement in July 2018.
BEWARE: Sometimes excavated natural material (ENM) or virgin excavated natural material (VENM) classification and reporting isn’t done right, or it is done correctly but other…
iEnvi delivered a NEPM‑compliant preliminary site investigation and groundwater monitoring report in four business days to meet settlement and bank requirements for a petrol station expansion at Sanctuary Point, NSW.
One uncertainty regarding per‐ and polyfluoroalkyl substances ( PFAS) is the total oxidisable precursor assay (TOPA).
iEnvi assessed water from two surface dams and one groundwater bore at Mt French, QLD to determine suitability for livestock watering and feedstock irrigation. Sampling found water suitable for stock with some crop restrictions; results were compared to ANZECC 2000 guidelines.
iEnvi managed PCB‑ and asbestos‑contaminated fill excavated for light footings at a Sydney western suburbs sportsfield, achieving regulatory approvals for interstate disposal and reducing council disposal costs by using targeted asbestos clearance, testing and specialist PCB destruction options.
Preliminary Site Investigation (PSI) and a proportionate Operational Environmental Management Plan (OEMP) prepared for an automotive recycling (wrecking) yard in south‑west Brisbane to manage scattered hydrocarbon staining without extensive soil sampling.
Desktop (Phase 1) preliminary site investigation for a proposed child care centre in Sydney’s Northern Beaches. The desktop study identified low contamination potential from on‑site history but recommended targeted soil sampling and an asbestos hazardous‑materials inspection before council proceeds with a development application.
Case study: PSI, combined geotechnical and environmental drilling, 30 soil bores to 5 m, 15 primary soil samples. Delivered reporting for planning permit in ~2 weeks; cost reported just over $10,000. Practical takeaways for developers on compliance, demolition hazards and cost efficiencies.
