First Stakeholder Meeting Carrizo Wilcox Aquifer Study January 28, 2010

Meeting Agenda Welcome and Introductions Background and Overview of Scope of Work Surveys Stakeholder Comments

Scope of Work Background 81 st Texas Legislature funded study through Texas Commission on Environmental Quality (TCEQ) TCEQ developed and executed Scope of Work with Bureau of Economic Geology

Scope of Work Background Scope of Work is divided into 7 primary tasks Final Draft Report Due to Texas Legislature on January 15, 2011

Scope of Work Task 1 Develop stakeholder list and contact information Survey stakeholders to identify any predominant groundwater management and protection issues and concerns, tabulate, and explain.

Scope of Work Task 1 cont. Develop and implement a survey for GCDs to obtain information required for study Examine rules, plans, and procedures to determine if they are based on sound science.

Scope of Work Task 2 Evaluate GCDs for enforcement of substantial compliance with adopted rules Tabulate number of enforcement actions since September 1, 2007

Scope of Work Task 3 Evaluate current regional and state water plans and all Carrizo- Wilcox WMS for conflicts with GCD Management Plans Hold stakeholder meetings with GMAs 11, 12, and 13

Scope of Work Task 3 Cont. Identify, tabulate, and describe existing and projected WMS that may/will impact groundwater use from the Carrizo-Wilcox Aquifer, including brackish groundwater

Scope of Work Task 4 Characterize GCD plans with respect to their ability to conserve and protect the Carrizo-Wilcox Aquifer Compare GCD plans, rules and procedures for compatibility with neighboring GCDs

Scope of Work Task 5 Review available records from GMAs 11, 12, and 13 and evaluate science behind ultimate Desired Future Conditions recommendations

Scope of Work Task 6 Evaluate Groundwater Availability Models to assess model runs of representative pumpage scenarios

Scope of Work Task 6 Cont Evaluate Groundwater Availability Models to assess – temporal variability of recharge – sources of water for pumpage, – timescales for impacts of pumpage on outcrop and Queen City –Sparta Aquifer

Scope of Work Task 6: Sources of Water for Pumpage Pumping in confined aquifer can obtain water from 1.Increased recharge from outcrop zone 2.from overlying and underlying aquifers in confined zone

Pre-development Conceptual Hydrologic Model

Steady-State vs. Transient System Steady-state system: recharge + discharge = 0 Transient to a new steady state: change in recharge (increase)+ change in discharge (decrease) + change in storage (decrease)= pumpage New steady-state (water table/piezometric surface lower): recharge + discharge = 0 How long is the equilibration time? including pumpage including CF reversal

Pre-development Post-development Conceptual Hydrologic Model 200 years ago SS: Baseline rejected recharge Artesian wells Future SS conditions with stabilized ~constant pumpage: Decreased rejected recharge = more losing streams No artesian wells, lower storage

Sources of Pumpage Water in Transient Conditions (1999) RegionPumpage Change in Storage Cross-Fm. Flow Deep Recharge Lateral Flow South (65%) 57 (20%) 45 (16%) -3 (-1%) Central (95%) 18 (1%) -8 (-4%) 0.3 (0%) North (40%) 45 (29%) 53 (34%) -4 (-3%) Combined (53%) 95 (20%) 120 (25%) 0 (0%) Values in parentheses represent percentages of pumpage.

Scope of Work Task 7 Determine if the presence of anthropogenic contaminants in the recharge zone and the potential pollution of the aquifer are issues that should be addressed, and if so, by whom

Scope of Work Task 7: Water Quality Water quality will be evaluated using TWDB and TCEQ databases and previous reports Stakeholders can submit information on any water quality issues of concern

Surveys The majority of the information that will ultimately be presented in the final report for The Carrizo-Wilcox Aquifer Study will be obtained through two surveys

Surveys  Carrizo-Wilcox Aquifer Groundwater Conservation District Survey  Carrizo-Wilcox Aquifer Interested Parties Survey

Surveys  Information requested by surveys will be submitted by the respondent via the Internet  All completed surveys are due March 31, 2010  Survey results will be made available for public inspection
