Groundwater Availability Model (GAM)

TRRP Training: 2022 Program

presented by: GSI Environmetal Inc.

Texas Risk Reduction Program regulations (TRRP; 30 TAC 350) establish consistent risk-based protocols for assessment and response to soil, groundwater, or surface water impacts associated with environmental releases of regulated wastes or substances.

Presented by GSI Environmental Inc., this popular and informative training series is a must for professionals who need a working understanding of TRRP and those needing to stay up-to-date with the latest TCEQ TRRP guidance and policies.

TRRP Training Course (2 Days): Provides an overview of the TRRP framework and step-by-step training on property assessment and response action procedures established under the TRRP rule

Attendees will become acquainted with rules, key guidance and policies covering affected property assessments, protective concentration levels, and response actions. The course material presents strategies for efficient project management in compliance with TRRP and explains the various report forms adopted by TCEQ.

Groundwater Availability Model for the northern portion of the Queen City, Sparta and Carrizo-Wilcox aquifers Basin, Texas

GSI led a team to update the northern portion of the Queen City, Sparta, and Carrizo-Wilcox aquifer system groundwater availability model (GAM) to provide a tool for predicting future groundwater availability and assessing water management strategies. The GAM update focuses on providing a better representation of the hydrostratigraphy to better simulate the complicated aquifer connections and the confined and unconfined aquifer conditions in outcrop areas. A Leapfrog geologic model was translated to a numerical model using unstructured grids in MODFLOW 6. MODFLOW 6 was used to simulate complex geologic features, such as faulting, outcrop and down-dip areas, cross-layer connections, islands, and pinch-out layers.

The model is calibrated to 34 years of hydrogeologic data and groundwater / surface-water interaction flux estimates (1980 through 2013) using annual stress periods for recharge and pumping. Sensitivity of the model to model parameters and model stresses are being examined and correlations between parameters and boundary stresses are evaluated.
