2. Consulting Philosophy
 A client should receive project deliverables that allow
them to make decisions with the provided data, reducing
their need for additional consulting services.
 The client should receive or have easy access to all source
data used to make interpretations for the project.
 Deliverables should be dynamic, allowing future research
to be easily integrated with the existing research.

3. Problem
Groundwater district staff need easy access to
groundwater data to make daily, permit and long-term
aquifer management decisions and communicate
those decisions to stakeholders.

4. Proposed Solution
Detailed interactive 3D hydro-stratigraphic or
lithologic models using an out-of-the-box software
module with easy-to-use tools.
 Visually identify formations and aquifers in subsurface
 Measure depth to tops, bases and aquifer thickness
 Investigate individual well attributes
 Visually identify well production zones
 Visualize water level changes and monitor DFCs

10. Benefits of lithologic models
 Quickly identify locations for higher
producing wells
 Evaluate potential of ASR
 Better quantify fresh and/or brackish
groundwater volumetrics
 Evaluate potential groundwater
contamination pathways

11.  Clients become more self-sufficient/ ess reliant on consultants
 Can replace or supplement GIS software
 Replaces the need for numerous cross-sections and maps

12.  Only requires minimal computer skills
 Source data is tied to model readily
available and updateable
 Predictive drilling and groundwater
exploration
 Investigate geospatial distribution of
screen and sand intervals water
quality, well production, aquifer
properties , etc.

13.  Evaluate local geology for permit applications
 Identify the correct aquifer for each of the district’s wells
 Create cross-sections at any orientation through modeled area

14.  Measure estimated distance between land surface to formation
tops or water levels, determine aquifer thickness
 Investigate alluvial resources and groundwater/surface water
interactions
 Compare water level surfaces, GAMs and TWDB reports
 Evaluate geospatial distribution of groundwater contamination,
aquifer properties or sand continuity
 Calculate volumetric estimates of aquifer resources

15.  Integrate previous GIS deliverables
 Define vertical brackish water zones
 Monitor injection well intervals

16. A 3D hydro-stratigraphic model provides a District with:
 A better understanding of aquifer’s geo-spatial complexity
 An evolving tool and framework for all future projects
 A platform to visualize all data types
 A powerful proactive tool for future litigation
 Gives the staff the power to make informed decisions quickly
