Mr. Michael G. McDonald

Mr. McDonald has 30 years' experience as a hydrologist with the U.S. Geological Survey (USGS) and McDonald Morrissey Associates, Inc. (MMA) in the analysis and simulation of complex ground- water flow systems.  As president and a principal investigator with MMA, Mr. McDonald has been involved with numerous hydrogeologic projects throughout the United States.  His recent experience includes providing technical support to Barrick Goldstrike Mines, the largest open-pit gold mine in North America; participating in a review team advising the Southwest Florida Water Management District on the construction and use of ground-water flow models; providing expert witness and consultation to a confidential client in Northwestern United States regarding the migration of contaminated ground water; and assisting Sierra Pacific Power Company in evaluating the effects of proposed pumping on the ground-water and surface-water in Truckee Meadows near Reno, Nevada.  While with the USGS, he developed the ground-water flow model MODFLOW, the most widely used model in the world.  As Regional Ground Water Specialist for the Northeastern Region of the USGS, he reviewed projects and advised hydrologists on the conduct of a wide range of hydrologic projects in the nineteen-state region.  Mr. McDonald has taught numerous courses on simulation of ground-water flow and transport throughout the US and Australia.  Mr. McDonald is currently serving a two-year term as a member of the Board of Directors of the AGWSE Division of the National Ground Water Association. 

Mr. Daniel J. Morrissey, RPG

Mr. Morrissey is co-founder and principal of McDonald Morrissey Associates, Inc.  Mr. Morrissey has 24 years of hands-on experience in solving quantitative hydrogeology problems, and is a recognized expert in the application of ground-water flow and solute transport models.  While with MMA, Mr. Morrissey has worked hydrogeologic investigations in more than 20 states.  As an example, his recent experience includes low-level radioactive waste site characterization in North Carolina, review of mining permits in Wisconsin, water supply studies in New England, and expert technical support for industrial clients at Superfund sites in several states. Prior to founding McDonald Morrissey Associates, Inc., he served as Chief of the New Hampshire/Vermont District of the Water Resources Division of the U. S. Geological Survey.  As District Chief, Mr. Morrissey supervised a staff of 30 hydrologists and technicians and was responsible for data collection, hydrogeologic investigations, and quality control for all work completed by the office.   He has conducted training courses in basic hydrology, surface geophysics, and ground-water flow simulation for the USGS, for the National Ground Water Association, state and local water management districts, and private clients in the United States and Australia.  

Mr. Charles P. Spalding, PG

Mr. Spalding has more than 19 years of experience in the conduct of quantitative hydrogeologic investigations.  During these 19 years, Mr. Spalding has applied many numerical and analytical models for the characterization of ground-water flow and solute transport, and performed hydrogeologic investigation management.  Prior to joining MMA, Mr. Spalding worked for HSI-GeoTrans, Inc. and was project manager for numerous hydrogeologic investigation projects including ground-water flow and solute-transport modeling for ground-water resource, plume delineation, and remedial design, site characterization of hazardous waste sites, and water resource development.   Mr. Spalding was responsible for the administrative management of the Site Characterization Group in the Sterling, Virginia office of HSI-GeoTrans.  He is experienced in a broad range of field tasks, including well drilling and installation, ground-water sampling, soil sampling, geophysical surveys, and aquifer tests.

Dr. Evan R. Anderman

Dr. Anderman has over 15 years of experience as a leader in the development of inverse-modeling techniques and is a coauthor of the recently released MODFLOW-2000.  Dr. Anderman holds Geological Engineering degrees from Colorado School of Mines and Princeton University.  Dr. Anderman has conducted research on applied parameter estimation in ground-water flow modeling.  In support of the modeling of the Death Valley Regional Flow System being performed by the U.S. Geological Survey for the Yucca Mountain Project, Dr. Anderman developed the following Packages/capabilities for MODFLOW-2000:

•           The Advective-Transport Observation (ADV) Package, in conjunction with Dr. Mary Hill of the U.S. Geological Survey and Dr. Eileen Poeter of Colorado School of Mines.

•           The Hydrogeologic-Unit Flow (HUF) Package to MODFLOW-2000, which allows users to define hydraulic properties using hydrogeologic units that differ from model layers.

•           The Model-Layer Variable-Direction Horizontal Anisotropy (LVDA) Capability to the HUF Package, allowing horizontal anisotropy to be oriented off the grid axes.

•           The Hydraulic-Conductivity Depth-Decay (KDEP) Parameter to the HUF Package, allowing users to define a parameter that controls the variation of hydraulic conductivity with depth.

Dr. Anderman has also worked on many other ground-water flow models, including the Republican River Basin ground-water flow model and the recalibration of the ground-water flow and transport model of the Hanford site in southeastern Washington state.
