Here are several examples of projects involving the use of three-dimensional visualization tools.

Chemical Manufacturing Facility, Ohio.
EVS and MVS, were used to demonstrate the nature and extent of contamination in a multi-aquifer system underneath an active manufacturing facility and on-site landfill. Visualization presentations were given to company officials, community groups and to the Ohio EPA. The use of EVS and MVS allowed for a clearer focus on the sources and extent of contamination. It also resulted in a greater understanding of the complex chemical and hydrogeological issues at the site, for all parties involved.

Automotive Manufacturing Facility, Ohio.
EVS and MVS were used in the development of a digital model of aquifer and aquitard materials using indicator Kriging. The resulting model challenged previous assumptions of a two-aquifer system divided by a clay aquifer, suggesting potential pathways between the aquifer. The new model was used along with visualizations of the extent of chemical contamination to better understand the potential movement of contaminants. The result was the conclusion that much of the persistent contamination at the site, was the result of DNAPL (dense non-aqueous phase liquids) in the subsurface on the upgradient side of the Site. The model was also used to aid in both the location, and type of remedial design.

Groundwater Flow and Contaminant Transport Modeling, Arizona.
EVS was used to visualize in three dimensions the results of MODFLOW and MT3D simulations of the spill of VOCs in a deep multi-aquifer system. The site had a complex pumping history, with flow directions changing directions with time, and also as a function of depth. The use of EVS allowed for a simple demonstration how contaminants had migrated vertically and horizontally over the decades.

Litigation Support for Landfill, New Jersey.
EVS was used to provide materials and presentations for settlement negotiations for cost-recovery litigation in respect to a landfill, a former Superfund site, in New Jersey. Although the remedial action was completed several years ago, cost-recovery had been ongoing. EVS was used to visualize the site, extent of contamination, and remedial action. Shortly after the use of EVS in settlement negotiations, a final settlement was reached.
