Neil Davies is a Senior Principal Civil and Environmental Engineer based in Georgia with more than 25 years of experience focused on the environmental remediation of former industrial manufacturing sites, and the design of civil infrastructure projects located throughout the United States and Europe.
Specializing in the management and technical direction of large multidisciplinary civil and environmental infrastructure projects, Neil's project experience includes treatment systems, pipelines and water distribution systems, tunnels (including soft-ground tunneling in compressed air), sea outfalls (tunnels and dredged cut), sea wall structures, and earth dam rehabilitation. He also provides technical and regulatory leadership for numerous complex environmental restoration projects conducted under CERCLA, RCRA, and state regulatory programs. His remediation experience includes the practical application of the following technologies: in situ containment of soft sludges and sediments; stabilization/fixation of contaminated soils and sludges; bio-treatment of soils; leachate and contaminated groundwater treatment (in situ and ex situ); thermal treatment of contaminated soils; in situ chemical oxidation treatment of groundwater contaminants; and permeable reactive barriers for groundwater remediation.
His remediation clients include multinational chemical manufacturers, manufacturers in the transportation industry, and agencies of the federal government. Neil also works with power utility companies to develop cost effective strategies for handling and disposing of coal combustion products (CCP) including ash and synthetic gypsum. He leads teams evaluating current and proposed disposal options for CCP, and residuals from flue gas desulfurization resulting from new air emission control units being brought on line at coal-fired units across the southeastern U.S.
To advance the state of the practice, Neil manages technology demonstration projects. At a NASA facility, he designed the first application of zero-valent iron to treat groundwater impacted by chlorinated solvents using an infiltration gallery. He has also conducted similar applied research involving macro porous polymer extraction (MPP.E.) and alcohol flushing technologies.
