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.
Problem
Groundwater district staff need easy access togroundwater data to make daily, permit and long-termaquifer management decisions and communicatethose decisions to stakeholders.
Proposed Solution
Detailed interactive 3D hydro-stratigraphic orlithologic models using an out-of-the-box softwaremodule 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

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
Clients become more self-sufficient/ ess reliant on consultants
Can replace or supplement GIS software
Replaces the need for numerous cross-sections and maps
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.
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
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
Integrate previous GIS deliverables
Define vertical brackish water zones
Monitor injection well intervals
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
