Abstract
Oil and brine production from deep horizons (1 km) in the Brookhaven oil field in southern Mississippi<br>has caused brine contamination of shallow (400 m) ground water. In order to evaluate the use of airborne<br>geophysical methods to map the extent of subsurface brine contamination, the U.S.Geological Survey, with<br>research funding from the Environmental Protection Agency, contracted a helicopter electromagnetic (HEM)<br>survey of the oil field area. The speciiic objectives of this research are to (1) evaluate the application of<br>airborne geophysical methods in an area of many cultural features that can interfere with these measurements,<br>and (2) interpret the subsurface distriiution of brine and fresh water. We applied a particular Geographic<br>Information System (GIS) can be to address these objectives.<br>The GRASS (Geographical Resource Analysis Support System) program developed and distriiuted<br>in the public domain by the Army Corps of Engineers Research Laboratory (CERL) has been adapted by the<br>USGS for use on a networked system of Hewlett Packard 9000 series 300 computers. Many other GIS software<br>packages available both commercially and in the public domain could be used to perform tasks similar to those<br>described here.
