  • Full Profile

    Kevin Simpson has 22 years of experience in contaminated land management and remediation including development of conceptual site models and remediation strategies; in-situ system design and implementation; and stakeholder management.

    He has developed and implemented strategies to progress sites from investigation to the point where sufficient remediation can be demonstrated and on to ultimate closure. Kevin has completed work to estimate the degree of financial liability attached to the remediation of a portfolio of petroleum related sites.

    Kevin has implemented over thirty in-situ systems including LNAPL skimming, total fluids, air sparge, soil vapour extraction, multi-phase extraction, vacuum enhanced pumping and more traditional LNAPL recovery including a trench and skimmer system in Fiji, installed in response to a major spill. He has implemented systems with a variety of equipment technologies including catalytic oxidisers, thermal oxidisers and activated carbon for off gas treatment, and tray and sparge type air strippers for groundwater treatment.

    Kevin was the State Practice Lead and Remediation System Design Manager for Australia / New Zealand based companies, providing senior review on design projects and maintaining the quality and standard of the design practice across the region. Additionally, Kevin was part of an Environment Technology team in Australia, where he played a key role in supporting remediation programs within the Asia Pacific region, and also in Europe and the U.S.

    During the earlier years of his career, Kevin project managed and completed the field work on a number of site assessment programs and contaminated soil excavations including a program of site assessments across Papua New Guinea.


    • Bachelor of Mechanical Engineering, University of Western Australia.

    Key Projects

    Energy Provider, Western Australia

    Groundwater and Remediation Strategy

    Technical advisor responsible for the strategy to remediate and manage soil and groundwater impacts from a diesel spill in a sand geology with shallow groundwater and nearby sensitive surface water. Strategy included a rapid response designed to remove freely available hydrocarbons and assess and mitigate immediate risks followed by preparation of longer term strategy.

    Key Experience

    Remediation Strategy Experience

    • Preparation of Remediation Options / Corrective Measures Studies for a number of petroleum storage and handling sites
    • Preparation of Clean-up Plans and Remediation Action and Implementation plans for petroleum storage and handling sites
    • Communication with internal businesses, environmental regulators, the public, and other stakeholders
    • Preparation of portfolio wide assessments of the financial liability attached to remediation of petroleum impacted sites
    • Principal in Charge for the development of a strategy to clean-up arsenic in soil at a decommissioned hospital site.

    Remediation Systems Experience

    Design or review, procurement, installation, operation, and monitoring of the pilot test and full scale phases of:

    • Two active skimming systems in Victoria including a solar powered system
    • Three total fluids systems in Victoria, New South Wales and South Australia
    • Over fifteen standard vertical well air sparge systems in Western Australia, Queensland and Northern Territory
    • Two air sparge trench systems to fine grained soils in Victoria and Queensland
    • Five soil vapour extraction systems in Western Australia and Queensland
    • Two vacuum enhanced skimming systems in Northern Territory and Victoria
    • Two multi-phase extraction systems with offgas treatment in Victoria and New South Wales
    • Trailer mounted air sparge equipment used to service up to five air sparge sites
    • Trailer mounted air sparge / soil vapour extraction equipment used to service two sites
    • Various combination systems throughout Australia including totals fluids / air sparge / soil vapour extraction
    • A number of mobile multi-phase extraction events.

    Additional Experience

    • Developed relationships with vendors of remediation equipment throughout the world
    • Developed event-based, vacuum truck multi-phase extraction procedures with focus on measures to mitigate potential hazards
    • Project managed and designed ‘on the run’, a trench-based product recovery system in response to a large spill
    • Prepared specifications, work plans, and procedures for pilot testing, installation, commissioning, operation and maintenance, and decommissioning for a number of remediation projects
    • Commissioned the CSIRO to conduct an air sparge system radius of influence study
    • Key figure in the development of Technology Safety Guidance “one pagers” including air sparge vapour migration and internal combustion engine gas supply
    • Completed an investigation into the potential for static ignition of flammable mixtures in PVC pipes used for multi-phase extraction. Enlisted the aid of a world recognised static expert based in Southampton, United Kingdom.
    • Reviewed the range of application and the advantages and disadvantages of offgas treatment technologies for in-situ remediation systems.

    Other Remediation Experience

    Project managed, conducted the field work and reported on numerous excavation type projects on a variety of sites and in a variety of geologies including a ten metre deep excavation with soil nail concrete wall shoring to support a major road.

    Environmental Investigation Experience

    Project management and completion of field work for ten environmental site assessments in Papua New Guinea.

    Other Services Experience

    Activities associated with the commissioning and operation of a research iron making facility (HIsmelt Corporation) including:

    • Commissioning and improving systems such as materials handling and delivery; hot air blast system; and various utilities such as cooling water and compressed air
    • Operation of plant and process during testing phases including control room operation; manipulation of mass balance software; and troubleshooting plant problems
    • Preparation of current best practices, commissioning, and training manuals
    • Training of staff in operation of plant and process
    • Work permitting.

    Project Management Experience

    • Overall project management of the remediation of a large scale pipeline spill project
    • Project and technical direction on a variety of petroleum hydrocarbon impacted sites.
