Abstract
A geographic information system was used to identify segments of the u pper Trinity River drainage network that ate within various distance t hresholds of solid waste landfills. U.S. Geological Survey digital lin e graph (DLG) data were used to create a hydrography coverage for the study area. Landfill coordinates were obtained from a database maintai ned by the Texas Natural Resource Conservation Commission. At a map sc ale of 1:100,000, 54 km (0.42%) of the drainage network are located wi thin 100 m of at least one landfill and 25 km of these stream segments are upstream of water supply reservoirs. The approach employed herein can prioritize local hydrogeologic investigations and facilitate stra tegic environmental monitoring to indicate potential landfill-derived contamination of surface water resources.
