Colorado Bar Association, Environmental Section (2017)

Mr. Gary Vanderslice was asked to present at a monthly meeting of the Environmental Section of the Colorado Bar Association on the topic of "3D Models for Contaminant Migration and Basin-wide Flow Modeling." Two vastly different case studies were presented to demonstrate 3D modeling tools used to generate a simple visualization model for a typical contaminant spill vs a much more complex 3D flow model involving thousands of wells. The contaminant spill case study shows preferential contaminant migration in sandstone from a single slug release from a tank battery. Mr. Vanderslice gave a "live software demonstration" of the model to discuss the components which allowed for meaningful interpretations regarding plume movement. The basin-wide geologic case study was for a multi-year development of a 3D basin-wide flow model in a complex hydrogeologic setting to support cost-recovery, remedial actions, and future ground water management in the basin.  The videos used in this presentation can be found on www.youtube.com/lytlewater.
