David F. Alden, P.E.

David provides technical support for Tersus’ portfolio of biotechnology-based solutions to manage complex, challenging environmental liabilities and reduce costs for site closure. He is a graduate of Universidad de las Americas-Puebla, Mexico, where he majored in Civil Engineering with a focus on waste-water treatment, has master’s degree from Joseph Fourier University in Grenoble, France, and he holds registration as a Professional Engineer in North Carolina. Davide worked for four years in the upstream oilfield sector performing offshore well tests and completion design and installation in the Gulf of Mexico. He participated in the in situ oil-shale extraction experiment in the Piceance Basin in Northwestern Colorado, where protecting groundwater was the main challenge. David's focus also includes development of innovative technologies to restore groundwater and soil at challenging sites. He is the lead author for US Patent 11,123,779 B2, Method and a Chemical Composition for Accelerated In Situ Biochemical Remediation. This patent is generally directed toward a method for supplying a mixture comprising ferrous sulfide and zero-valent metal particle reactants into soil pathways to biologically react with dissolved contaminants in groundwater.
