  • 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.
