Dr. David Hyndman
Efficient
Large-Scale Bioremediation in a Heterogeneous Aquifer:
The Schoolcraft Bioaugmentation Experiment
Dr. Hyndman's presentation will examine how ground water flow and contaminant transport models can be used to design bioremediation systems and evaluate the influence of heterogeneities. The Schoolcraft bioremediation system, a collaboration between hydrogeologists, microbiologists, and environmental engineers, has achieved more than 95 percent efficiency over a period of three years.
Hyndman received his B.S. in hydrology from the University of Arizona, and his M.S. and Ph.D. degrees in hydrogeology from Stanford University. He has worked for the Water Resources Division, USGS, and Oak Ridge National Laboratory, and he serves as an associate editor for both the journals Ground Water and Water Resources Research. His research focuses on:
· Aquifer characterization
methods using three-dimensional seismic, radar, and tracer data.
· Modeling the impacts of land use on water quality.
· Imaging contaminant plumes using ground penetrating radar.
· The influence of seasonal recharge pulses on REDOX zonation.
· The design of bioremediation systems.
· Modeling microbial transport and contaminant biodegradation.
The lecture series, sponsored by the National Ground Water Educational Foundation through a grant from NGWA, is named in honor of Henry Darcy's 1856 discovery of the basic law governing ground water flow. He was designing sand filtration systems for the water supply of Dijon, France and conducted experiments to determine how large and thick the sand beds would need to be in order to process the necessary volume of water. He found that flow rate could be calculated from the gradient, area, and sand properties and published this as an appendix to his report. The results of his experiment are basis of the empirical law that bears his name.
The lecture series was established
in 1986. No fees are charged. More information on the series can be found on
