简介

Research Area • Abiotic and biochemical catalysis of reductive dehalogenation. • Oxidation of hazardous organic compounds in soils using H2O2 and Fenton-derived hydroxyl radicals. • Engineered systems leading to water reuse following infiltration and aquifer storage – the effect of soil-aquifer treatment on organic residuals, available nitrogen forms and pathogens in treated municipal wastewaters. • Trace organic chemicals in products derived from wastewater treatment – reclaimed water and biosolids. • Engineering methods for minimum-cost salt removal from public water sources. Curriculum Vitae Educational Qualifications • BSME, US Naval Academy, 1969 • M.S., Environmental Engineering, University of North Carolina at Chapel Hill, 1976 • Ph.D., Environmental Engineering, California Institute of Technology, 1986 Research Research is concentrated in areas pertinent to the purification of water and wastewater for human consumption and reuse. There is a strong emphasis on wastewater reclamation and reuse, taking advantage of combinations of engineered and natural processes such as advanced oxidation and soil-aquifer treatment to provide water purity and defense in depth against human and environmental exposure to residual contaminants. Systems analytical approaches are used to provide assurance of water security (reliability in meeting projected water demands) at lowest cost and with acceptable risk in chronically water short areas like the southwestern United States through combinations of engineered measures and water use management. This function must be carried out in the presence of increasing uncertainty related to climate variation and population growth projections.
