Dan Erskine has 22 years of experience conducting investigations in geology, hydrology, geochemistry and environmental science. His expertise includes developing site work plans and remedial action plans, conducting risk assessments, and performing geologic and hydrologic field investigations. Dr. Erskine's efforts have focused on the design of sampling programs, laboratory analysis, data interpretation, investigations involving groundwater contamination remediation and geochemical modeling of natural groundwaters, and fate and transport of hazardous constituents. He has directed soil and groundwater investigations at a wide variety of contaminated sites, including radiologically contaminated sites in several states, sites with metals contamination related to mining and milling, solvent- and fuel oil-contaminated soil and groundwater sites, and residential areas with subsurface contamination. He has led numerous analytical and numerical groundwater flow and solute transport modeling projects to evaluate remedial system designs during the feasibility study process, risk to human health and the environment, and performance of remedial measures. Dr. Erskine has particular expertise in the use of geochemical codes that include PHREEQC and MINTEQA2. He has completed projects in compliance with U.S. Environmental Protection Agency (EPA), National Regulatory Commission (NRC) and regulatory programs governed by the states of Colorado, Utah, Wyoming, New Mexico and Pennsylvania. Dr. Erskine has direct experience successfully negotiating with regulators. For two years, he was director of innovative remedial technologies for a remedial services firm that works with university researchers, state and local regulators and the U.S. Department of Energy (DOE) to develop innovative in situ bioremediation technologies for nitrate and uranium contamination. He also served as site geochemist for nine DOE project sites, working on various aspects of groundwater hydrology and geochemistry.
