Our Environmental Consultants based in Sydney, Newcastle, Brisbane and Melbourne undertake a wide variety of Contaminated Land Investigations for projects throughout Australia. Whether clients require a preliminary investigation or a detailed site assessment, our multi disciplined team can determine whether contamination exists and what impact it could have on the site’s current and future use.

We Specialise in All 4 Phases of Contaminated Site Investigations

Phase 1 – Preliminary Site Investigation (PSI)
Identifies past and present potentially contaminating activities. Provides a preliminary assessment of site contamination.

Phase 2 – Detailed Site Investigation (DSI)
Gives comprehensive information on type, extent and level of contamination.

Phase 3 – Remedial Action Plan (RAP)
Sets remediation goals that ensure the remediated site will be suitable for the proposed use. Documents in detail all procedures, plans and environmental safe guards to be implemented to reduce risks to acceptable levels for the proposed site use.

Phase 4 – Validation (VAL)
Ensures that the objectives stated in the Remedial Action Plan have been achieved and confirms statistically that the remediated site complies with the clean-up criteria set for the site.
