EI Australia’s in-house Environmental Engineering team consists of a range of scientists, engineers, certified environmental practitioners and licensed asbestos assessors. Our team specialises in the Contaminated Land Management (CLM) of soil, groundwater, surface water, vapour and hazardous ground gases. For over the last 25 years, our clients have had the confidence that we have the knowledge and experience of successfully applying practical and sustainable solutions.
EI Australia’s Contaminated Land Management (CLM) team has extensive knowledge in providing Phase 1 Preliminary Site Investigations (PSI), Phase 2 Detailed Site Investigations (DSI), Remediation Action Plans (RAP) and Site Validation Reports. Our team has the skill and experience to evaluate a range of sustainable remediation options in accordance with the State Environmental Planning Policy (SEPP 55) and develop an approach that is practical, affordable and technically feasible with regards to project outcomes and meeting with the regulator’s approval (i.e. council, EPA and Site Auditor).
In addition to any initial CLM investigations, EI Australia’s CLM team has the skill and experience to work with our clients to remediate soil and groundwater contamination in the ground (in-situ) or after excavation/ pumping (ex-situ).
After a thorough evaluation of a range of remedial options to select the most feasible and sustainable strategy, in consideration of impacts to the environment, as well as technical feasibility, projected clean-up timeframes and affordability, EI Australia can develop a remediation approach that meets with legislative, regulatory and Site Auditor approval and achieves the required project outcomes.
Remedial methodologies used successfully on previous projects have included:
EI Australia’s CLM team has the skill, knowledge and experience to help waste generator’s (i.e. contractors, builders, developers, landfill operators) to classify the wastes they produce in accordance with the NSW Environment Protection Authority (EPA) guidelines and exemptions. EI Australia understands that the classification and offsite disposal of soils is often a costly component of any construction project and should be completed with minimal delays. Our team of experts regularly provide technical, affordable and practical solutions to classifying waste for offsite disposal with expedited turn-arounds.
Government regulators increased emphasis on the control and management of landfill sites and the assessment of soil, vapour emissions and environmental impacts from migrating groundwater contamination requires experiences CLM practitioners to ensure compliance. Our capabilities and the services provided in relation to landfill sites are extensive:
Given the nature of waste disposal operations and their consequent long-term implication on the environment, EI Australia has substantial experience in all aspects of landfill operation and management and is ideally placed to provide landfill owners/ operators with environmental management plans, which not only meet regulatory requirements, but are also practicable.
In addition to meeting legislative requirements, a performance-based landfill environmental management plan prepared on the basis of best management practices is also a valuable tool for managing the long-term liability of landfilling operations.
Assessments are commonly required for establishing baseline conditions and predicting future movement, quantity and quality of groundwater and the potential for leachate leaking from landfills to cause contamination.
Our team is experienced in the design and implementation of leachate management plans and groundwater treatment systems at major landfills nationally, covering a wide range of geological conditions. Following site assessments and identification of potential problems, EI Australia will design and undertake or manage trials of various technologies incorporating physical, chemical and biological treatment.
The term Acid Sulfate Soils (ASS) is used to describe sulfide-rich, natural soils, sediments and peat deposits, which can lead to the formation of sulfuric acid as a result of material disturbance and exposure to the atmosphere. ASS occur all around the country and if left unmanaged the sulfide oxidation process can make the groundwater acidic, causing naturally-occurring heavy metals (such as iron, aluminium, arsenic and copper), to be leached from the soil and transported to surface water bodies. This can lead to adverse impacts on vegetation, aquatic organisms (including ‘fish kills’), as well as causing damage to steel and concrete structures (corrosion) such as pipes, culverts, bridge piers or retaining walls.
EI Australia has the skills, capability and experience to assist with the identification and management of all Acid Sulfate situations.
Our CLM team have a breadth of experience across both the upstream and downstream petroleum industry sectors including the assessment, remediation, and decommissioning of underground and above-ground petroleum storage systems (UPSS) in accordance with current legislation, regulatory understanding and requirements, and health and safety stewardship.
EI Australia supervise remediation and validation of underground storage tanks (USTs) in accordance with the following guidelines and standards;
The management and supervision is required by a suitably qualified environmental professional to reduce volatilisation risks and ensure the remedial works are competed in accordance with the above requirements.
