In memoriam — Charles Stephen Haase (1951-2022)
December 5, 2022

Charles Stephen (Steve) Haase, Ph.D., of Jonesborough, TN passed away on November 15, 2022. Steve was born on September 20, 1951 in Duluth, Minnesota. His bachelor’s and master’s degrees in geology were received, respectively, from Carleton College and Brown University in 1973 and 1975. After receiving a Ph.D. degree in geology at Indiana University in 1979, he continued post-doctorate studies in geochemistry at Yale University.

Steve started his professional career in 1980 at the U.S. Department of Energy’s (DOE) Oak Ridge National Laboratory (ORNL) as a research scientist; and most of the large body of his peer-reviewed publications relates to geohydrologic investigation he initiated in the ORNL Y-12 Plant area (See:

In 1991, Steve joined the staff of the NM Bureau of Mines & Mineral Resources, a research division of NM Tech, where he was co-leader of a multi-institutional hydrogeologic investigation in the northern Albuquerque Basin. During the next 2 years, he made a number of seminal contributions to our present understanding of the hydrogeology and hydrochemistry of that area (see references below). His geohydrologic research in New Mexico continued through the mid-1990s, when he was Director of Environmental Services at the Albuquerque office of GRAM, Inc.
