Lipan Aquifer: Structure and Brackish Groundwater
Study Summary:
The goals of the study are to (1) map and characterize the brackish parts of the major and minor aquifers of the study area in greater detail using existing water well reports, geophysical well logs, and available aquifer data and (2) build datasets that can be used for groundwater exploration and replicable numerical groundwater flow models to estimate aquifer productivity.
The study area includes all or portions of the following counties: Coke, Concho, Irion, Runnels, Schleicher, Sterling, and Tom Green. This study area was selected because of the extreme drought and depleted water resources of the area.
The objectives of the study are to:
- collect, analyze, and interpret thousands of water well and geophysical well logs;
- map the geological boundaries of the Leona Formation and underlying Permian formations;
- map the distribution of total dissolved solids in the aquifers;
- map the distribution of key chemical parameters of interest to desalination;
- map the net sand distribution in the aquifers;
- estimate the volume of fresh and brackish water in the aquifers;
- incorporate all information into the publicly available BRACS Database and study GIS datasets;
- prepare and publish study findings in a peer-reviewed TWDB report.
- Study Team Members:
- Matt Webb and Mark Robinson
- Study Start Date:
- Summer 2015
- Study Completion Date:
- September 2017
- Benefits:
- The team anticipates that the publicly available data and report produced by this study will aid researchers and decision-makers in the selection or elimination of locations for site specific studies on groundwater desalination and aquifer storage and recovery.
