Abstract
Modeling Groundwater Contours and Compound Iso-concentrations using Spatial Analyst Track: GIS Organization, Management, and Implementation Author(s): Vaibhavi Shanbhogue, Cristin Taft, Allison Jelinek, David Towsey Remedial activities at a number of sites has resulted in large amounts of data being collected which include water levels, groundwater data, and product thicknesses. To be able to interpret and visualize the data collected, we used Spatial Analyst to model groundwater contours, compound iso-concentrations and product thicknesses. Information collected has been stored in a Microsoft Excel Database and utilized in GIS to create shapefiles containing attributes like groundwater elevations, compound concentrations and product thicknesses. The information was queried from the shapefiles and using spatial analyst, groundwater contours, contaminant iso-concentrations and product plumes were generated. Based on the results of this exercise, our understanding of the hydrogeology, direction of groundwater flow and product movement has been enhanced which has aided in developing a refined site conceptual model. This study shows one of the many applications of GIS that gives viewers a better perspective of the contaminant behavior on their site.
