Common activities that can cause contaminated land include service stations, fuel and oil storage sites, mechanical workshops, cattle tick dips and spray races, tanneries, wood treatment sites, agricultural chemical use and landfills. The risk of land contamination is higher because of the chemicals and toxins used and released into the environment from these activities.
ADG offers the following range of contaminated land services:
- Due Diligence investigations for risk assessment during property acquisitions.
- Stage 1: Preliminary Site Investigations to develop a site history and identify potential sources of contamination and associated contaminants.
- Stage 2: Detailed Site Investigations including soil, soil vapour, landfill gas, surface water and groundwater sampling. Testing programs are designed to identify the extent of contaminants above guideline criteria levels. ADG can also assess potential contaminant migration and exposure pathways.
- Remedial Action Plans and Site Management Plans for submission to local and state government (sometimes called a ‘Remediation Action Plan’ or just ‘Remediation Plan’). ADG has experience with a wide range of remedial technologies to apply based on the site conditions, contaminants of concern, remediation goals and minimising costs.
- Remedial Work Supervision and Management of contractors and projects during site remediation.
- Validation including supervision of all remedial works and validation sampling to confirm post remediation contaminant levels.
- Preparation of Site Validation Reports including Remediation and Validation Reports, and Site Suitability Statements.
- Waste Classification Reports to obtain government approvals and disposal permits for the resulting waste materials and contaminated soil.
ADG has suitably qualified persons (SQPs) in house who work closely with contaminated land auditors in NSW and QLD. Engaging an SQP ensures compliance with the Department of Environment and Science (DES) and EPA requirements.
