Earle, R. GIS Analysis of Available Data to Identify Regions in the US Where Shallow Ground Water Supplies are Particularly Vulnerable to Contamination by Releases to Biofuels from Underground Storage . Presented at ORD Biofuels Workshop, Sacramento, CA, May 11 - 13, 2010.
Impact/Purpose:
GIS analysis of available data to identify regions in the U.S. where shallow ground water supplies are particularly vulnerable to contamination by releases of biofuels from underground storage tanks.
Description:
In this slide presentation, GIS was used to perform a simple numerical and spatial analysis of shallow ground water drinkers and existing motor fuel service stations in the contiguous U.S. This analysis yielded an estimate of the probability of impact. "Vulnerability Indeces" were calculated and mapped using 1990 US Census Tract Areas. The analysis provides a visual representation of those areas where the potential for impact is greatest.
