Sparta Aquifer, East Texas: Brackish Groundwater Study
The goals of the study are to (1) map and characterize the Sparta Aquifer 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 to estimate the volumes of groundwater in as many as five salinity classes. The study area includes all or part of 55 counties in east Texas.
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 Sparta Aquifer and the bounding aquitards: Weches and Cook Mountain;
- 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 newly created information into the publicly available BRACS Database and study GIS datasets;
- prepare and publish study findings in a TWDB report.
- Study Team Members:
- Kristie Laughlin, Sydney Weitkunat, and Olga Bauer
- Study Start Date:
- Summer 2020
- Study Completion Date:
- Fall 2022
- The study will develop data and a report that will be available to researchers and decision-makers to assist in the site selection of future groundwater desalination and aquifer storage and recovery projects. The Upper Coastal Plains East study area will be split into four separate studies: 1) Sparta Aquifer, 2) Queen City and Carrizo-Wilcox aquifers, and the 3) Yegua-Jackson Aquifer.
