FreemanGIS has been conducting Segment Identification risk assessments since 2001. To identify pipeline segments that could affect an HCA, we calculate draindown along the pipe and consider terrain, soil type, surface water flow, and underlying aquifer systems. Our approach produces cogent spill scenarios that predict the direction and speed of transport from hypothetical releases along the pipe. We couple background knowledge about the HCA resources in the area with a geographic intersection of spill plumes and HCAs to predict potential affect.

FreemanGIS partnered with RCP, Inc. to develop a model that traces pipeline spills downstream and over land. The model is an extension to ArcGIS. Its tools are accessed through an ArcMap toolbar, where the commands use ArcEditor and Spatial Analyst functionality to render results. The model accepts operator-defined pipeline specs and outputs spill plumes as shapefiles that can be edited as needed to reflect known reality.

We offer 2 cost effective ways to meet your spill modeling needs:

• license the toolset to model spills in-house
• enlist us to run the model and provide documented results as maps and shapefiles
