Mr. Mackey provides extensive experience in solid waste, hazardous waste, and leachate management issues. His past and ongoing participation in local, state, and federal research projects and technical societies has allowed Mr. Mackey to continuously integrate the latest technology into waste containment design, site assessment, and technology review projects. Through his varied background and active role in technical societies, Mr. Mackey has been recognized by his peers as a leader and internationally known expert in the field of waste containment design and geosynthetic materials.

He has more than twenty years of professional experience including biological and chemical degradation of waste materials, landfill bottom liner design and construction, landfill closures, groundwater monitoring, various waste management structures, and permitting of waste management facilities. His assistance has been sought for specific projects, task groups, and committees because of his varied experience and in-depth technical understanding of landfill liner and leachate collection systems. Projects he has managed include the development of National Solid Waste Regulations and Standards for the Kingdom of Thailand, preliminary assessment and remediation designs of solid waste disposal sites in Thailand, and a forensic assessment of liner and leachate collection system for the Delaware Solid Waste Authority's Central Disposal Facility.
