Craig J Brown, Ph.D.

Biography

Craig Brown began working for the USGS as a hydrologist in 1993. He works mainly on studies dealing with aquifer geochemistry and the occurrence and mobility of contaminants and the use of stable isotopes and age tracers for study of groundwater/surface-water interactions.

Prior to his work with the USGS, his experience includes:
May 1992 to February 1993: Hydrogeologist--Technical Collaborator, Brookhaven National Laboratory, Biomedical & Environmental Assessment Group, Uptonmulti-media modeling of radionuclides.
June 1988 to June 1991: Hydrogeologist, Geraghty & Miller, Inc., Annapolis, MD, Hydrogeologic and remedial investigations at sites throughout the U.S.
January 1987 to June 1988: HydrogeologistEwers Water Consultants, Inc., Richmond, KY, Hydrogeologic investigations at karst sites in the U.S. and Puerto Rico
