Landfill Gas Emission Investigations and Leachate in Groundwater Monitoring

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.

‍

Leachate Treatment

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.

Acid Sulfate Soils

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.

Underground Storage Tank Removal, Decommissioning, Validation

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;

‍

• POEO (2014) Protection of the Environment Operations (Underground Petroleum Storage Systems) Regulation 2014; and
• Australian Standard (2016) The removal and disposal of underground petroleum storage tanks, AS 4976-2008 (Reconfirmed) dated 15 July 2016.
• EPA (2014) Technical Note: Investigation of Service Station Sites;
• DECCW (2008) Guidelines for Implementing the Protection of the Environment Operations (Underground Petroleum Storage Systems) Regulation 2008;
  
  

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.
