| Abstract | Rapid development and population growth are occurring in Webb County in south Texas (fig. 1). Water managers need information on the ground-water resources of the area to address the increased demand for water caused by the development. To help meet this need, the U.S. Geological Survey (USGS), in cooperation with the City of Laredo, began a study in 1997 to assess the ground-water resources of the county. This report describes the quality of ground water determined from water samples collected during 1997-98. Webb County receives an average of 20 inches (in.) of rainfall annually. Recharge to the aquifers occurs primarily by infiltration of precipitation on the aquifer outcrop (fig. 1). Regionally, depth to the aquifers increases in a southeasterly direction from the aquifer outcrop. The primary sources of ground water in Webb County are the Carrizo aquifer, Queen City-Bigford aquifer, Laredo aquifer, Yegua aquifer, Jackson aquifer, Gulf Coast aquifer, and alluvium deposits (table 1). The [ndio, Bigford, and Goliad Formations and the alluvium deposits were not included in this study because suitable wells were not available to be sampled. |
