Charles Kreitler has conducted ground-water investigations in Texas and the southwestern United States for more than 20 years. His experience includes water resource investigations of sandstones and limestones, fault activation in the Texas Coastal Zone, and site characterization for both high-level and low-level nuclear waste disposal sites in salt domes, evaporites and thick unsaturated sections in arid settings. He has worked on problems associated with injection of brines from the petroleum industry and hazardous wastes from the chemical industry. He has conducted detailed characterization of contaminant sites in both porous media and fractured bedrock. He has written books and monographs on geochemistry of brine contamination, wellhead protection and ground-water flow through heterogeneous sandstones. He has been the author of more than 100 technical articles and contract reports.
