  • Full Profile

    Ken Mival is an EPA accredited Environmental Auditor (Contaminated Land) with over 45 years’ experience in geology, engineering geology, environmental engineering and auditing, throughout Africa, UK, NZ, Singapore, PNG, and Australia. Over the past 25 years Ken has primarily focused on auditing and management of contaminated land. He has undertaken environmental audits for many large urban and iconic developments; large chemical and manufacturing plants; clean-up of dioxins; and landfill construction and landfill gas sites.

    Ken has undertaken over 200 statutory environmental audits and due diligence and regulatory compliance audits for property transfers, factory shut downs, closed landfills and for operational landfills and clean-up of former industrial sites for residential and commercial developments. He has provided expert evidence to VCAT, Planning Panels Victoria, and the Magistrates, High and Supreme Courts, in several jurisdictions on: dam failure; contaminated land; illegal landfills; landfill gas risk; and the cost of remediation of, and responsibility for, contaminated land. Additionally, Ken has provided expert advice to EPA on landfill gas risks; human health risks, and risks to large animals relating to arsenic and mercury contamination from mining; and on clean-up criteria for dioxins.

    He has taken part in numerous workshops and studies with EPA Victoria on improvements to the Victorian regulations and guidelines with regard to contaminated land management; groundwater and waste. Ken currently represents EHS Support at the Landfill Auditors Workshops (held quarterly) and on their Groundwater committee.

    He is widely published and has contributed extensively to the regulatory environmental framework in Victoria and presented many papers and articles for books, conferences, and seminars on engineering geology, contaminated land clean-up, bushfire impacts and disaster planning.

    Together with the consultants to Melbourne Water, Ken in his auditor capacity won the Consult Australia Engineering Excellence Gold Award in 2011 (Environmental Category) for the clean-up of Dioxins at the 180 hectare Dandenong Sewage Treatment Plant.

    Ken conducted an Environmental Audit under Section 53X of the EP Act of the Melbourne Water 193ha former Dandenong Treatment Plant, that included the establishment of criteria for remediation of Dioxins Remediation; then went on to complete audits for the residential area then the industrial zones from 2007 to 2011, plus a 53V Audit of construction of this 6 cell landfill as “CALM” repository for containment of dioxin wastes (2008/10). This included review of design and audit of construction of: leachate system; landfill gas management; cell base linings and cap construction.

    Fisherman’s bend – Multiple Audits

    With the re-zoning of Fisherman’s Bend into “Capital City Zones” Ken has been providing advice to EPA on what worked with Docklands and also undertaking audits of two major properties. The first for a twin tower high rise on Lorimer St for Little Projects, now under construction, and the second ongoing audit for over 300 townhouse lots on the former Symex Oleo Chemical site. This included approval of designs for vapour and odour management capping and the use of “Liquid Boot” inside a heritage building for 6 apartments. Stage 1 audit was completed in 2015 and Stage 2 is currently in progress.

    Braybrook Carpet Manufacturer

    Ken is undertaking a 53X audit of a former carpet manufacturing site that is under notice from EPA due to PCE pollution in groundwater. Multiple groundwater wells have identified the areas impacted and client is exploring remediation options. Likely to continue to 2017/18.

    Ken started auditing the 150yr old former ICI chemical factory site at Yarraville in 2000, completing an audit in 2005 followed by independent auditor review of on-going groundwater monitoring, assessment of organic chemical areas and work plans for a large scale clean up planned to occur in 2016/17. Contaminants included a large range of chlorinated organics, metals, aniline and monocyclic aromatics.

    Fisherman’s bend – Symex Plant Closure

    Prior to the demolition and audit for over 300 townhouse lots on the former Symex Oleo Chemical site. Ken undertook a section 53V audit to provide EPA with confidence that the site did not remain a significant source of pollution. This permitted the EPA to close the original scheduled premises license and the client to sell the site.
