ENV-04-197 Application of Computer Visual Technology to Improve Site Characterization and Remediation

Description:

Historically, characterization and subsurface investigations at refinery locations require significant data management resources and expense. In particular, the size, complexity of the physical setting, and variability in constituent composition are aspects unique to refinery sites. As a result, effective information management is critical to reducing costs and developing effective remedial programs. New applications in three-dimensional computer visual imagery have enabled site characterization information to be readily illustrated at large-scale sites, such as refineries. This technology can facilitate technical understanding and communication of site data. Features commonly illustrated include the ground surface, well construction information (well screens and casings), geologic strata, and potentiometric groundwater surfaces as well as soil and water chemical concentrations. These features can be illustrated collectively or independently. As a result, technical interrelationships between physical and chemical features become more readily apparent. Once apparent, data gaps can be assessed and more effective remedial approaches can be developed. Visual imagery is also an effective management tool. For example, images can be easily updated, which allows regular gauging and sampling information to be readily evaluated. In addition, the technology provides a tool to enhance communication of technical issues to various parties, including regulators, consultants, and non-technical individuals within the community. Visual imagery technology produces electronic still images as well as interactive animations. Files can be transferred over the Internet or placed on CDs for storage. Examples of visual imagery analyses are presented to demonstrate how this technology can improve subsurface investigations and site management.
