Carrizo-Wilcox Aquifer Study Overview

The 81st Texas Legislature directed the Texas Commission on Environmental Quality to "conduct a study of the characteristics and impacts on groundwater planning in the Carrizo-Wilcox Aquifer." (General Appropriations Act, Article VI, Texas Commission on Environmental Quality, Rider 36) In order to accomplish the legislative intent of this study, the Texas Commission on Environmental Quality has entered into a research contract with the Bureau of Economic Geology at The University of Texas at Austin to collect and review a wide variety of information, develop datasets and conduct a series of analyses regarding current activities related to groundwater management of the Carrizo-Wilcox Aquifer in Texas.

This study will involve significant stakeholder input to a number of questions that are posed in the scope of work for this study. In particular, the study will seek to understand (1) the quality and quantity of scientific information that has been utilized by groundwater conservation districts that manage the Carrizo-Wilcox Aquifer, (2) the compatibility of different management approaches currently in place for the Carrizo-Wilcox Aquifer, and (3) predominant groundwater management and protection issues and concerns from stakeholders of the Carrizo-Wilcox Aquifer.

The complete scope of work for this study is available here.

Announcements of upcoming stakeholder meetings, stakeholder surveys, interim, draft, and final reports will be posted and maintained on this web page.
