Abstract

CERCLA Analytical Data Automation Using ModelBuilder and ArcObjects
Track: Modeling
Author(s): Kelly Boyd, Adam Dunlap, Hugh Carr, Jenette Gordon

The Environmental Management Program at NASA's John C. Stennis Space Center (SSC) applies GIS to analyze Comprehensive Environmental Response, Compensation, and Liability Act(CERCLA) data collected at seven locations throughout the 22-square mile site. The site contains nearly 150 active wells drilled into multiple water bearing zones. Samples are periodically taken from the wells and analyzed in the lab to detect the chemical presence of trichloroethylene, dichloroethylene, and vinyl chloride in parts per billion (ppb). The samples are interpolated in Spatial Analyst using the Kriging method. The natural logarithm of the values serves as the Z-value to control the extent of the plume. Known locations where no chemical has been detected are included as control points. Automation of the analysis through Model Builder and Python scripting will be implemented to streamline the process. Further, auto-generation of output maps using ArcObjects will save time and eliminate the potential for error. Data are also displayed using ArcGIS Server.
