Managing Acid Sulfate Soils

Without careful management, disturbing acid sulfate soils can have serious downstream environmental, economic, engineering and health impacts, and can restrict development, construction and agriculture in affected areas. Environmental Earth Sciences has significant experience in developing site plans to effectively manage the potential risk associated with Acid Sulfate Soils. When removed from a site, acid sulfate soils are classified as waste and can have significant cost implications for...

EESI Keeping Our Communities Safe and Clean

The Environmental Earth Sciences team in New South Wales has been working closely with local councils, particularly in the western regions of Sydney, by assisting in the waste classification of stockpiled material. These stockpiles are dumped on the side of roads from unknown sources and left for council to remove. Our team samples the soil material for analysis and compares the results to the NSW EPA Waste Classification Guidelines. We notify the council of the findings and they are then ...

Metal contamination in soils

The Centre for Contaminant Geoscience (CCG) was engaged to design a remediation technique to maximise the onsite reuse of soil after metal contamination in soils had occurred.   THE SOLUTION CCG developed a technique to immobilise metals such as lead and mercury in soil through the formation of non-soluble mineral complexes. This technique mitigates the associated environmental and health impacts and has the potential to be used on complex mixtures of metals. &...

Property disposal – industrial make good

GreenPlus Property was engaged by One Steel Recycling to carry out an Industrial Make Good for a Property Disposal. The location was 0.5 hectares within an industrial site that had been leased by the client for the last 5 years. As the lease was drawing to its end, the client was informed by the landlord that all Make Good obligations were required to be met prior to site vacation.   THE SOLUTION GreenPlus Property was instructed to represent the client in all ...

Major rail project, NSW

A 38 hectare rail project site in Newcastle, NSW was found to have in excess of 110,000m³ of potential acid sulfate soils. Potential acid sulfate soils have the ability to create considerable financial issues and timeline delays if disturbed and not managed appropriately. EESI Contracting and the Centre for Contaminant Geoscience (CCG) togeth...

Moree case study

During an upgrade of playground equipment at a kindergarten in Moree, an old tarmac surface was uncovered. Moree Council’s testing of the tarmac showed an elevation in polycyclic aromatic hydrocarbons (PAHs), some of which are considered carcinogenic. The data was reviewed and a risk assessment completed. Although it was acknowledged that there were no current pathways of exposure, it was determined that remediation should be undertaken.   THE SOLUTION EESI Con...

Phytoremediation

EESI Contracting undertook a remediation project at an operational manufacturing plant. A pro-active approach to remediating impacted waters at this operating site was applied using various remediation technologies including phytoremediation.   THE SOLUTION To achieve the required groundwater remediation outcome, EESI Contracting implemented; –    a phytoremediation program to reduce water volumes requiring treatment; –    construction of an attenuation and ad...
