Hydro GeoAnalyst

Environmental Data Management & Visualization

Hydro GeoAnalyst (HGA) is our comprehensive and easy-to-use environmental data management system. HGA integrates customizable database structures used around the world with state-of-the-art tools for data interpretation, statistical analysis, Geographical Information System (GIS) mapping, data charting, and visualizations in two or three dimensions.

Our new Hydro GeoAnalyst Plus (HGA+) integrates geochemistry features of AquaChem into the data management and extensibility capabilities of HGA.

Why Choose Hydro GeoAnalyst?

Hydro GeoAnalyst (HGA) Software Interface

With Hydro GeoAnalyst, environmental professionals, geoscientists and government agencies have all the tools required to effectively and efficiently manage large volumes of data, and make informed decisions about environmental and water resources.

HGA consists of an application that connects to an SQL Server database and facilitates data management, analysis and interpretation, and collaboration through various purpose-built modules.  HGA helps you work with large volumes of environmental data without requiring in-depth knowledge of SQL.  HGA+ extends these capabilities by adding modules specifically designed to work with geochemical data and a console for use R to get even more out of your data.

Improved Data Quality 

Hydro GeoAnalyst standardizes your organization and intelligently validates all data upon import, ensuring it meets quality requirements for reliable analyses and informed decision making.

  • Hydro GeoAnalyst helps you kick start your project by providing an environmental database template that consist of tables and fields for common environmental data types, common well profile templates and report templates.
  • Increase efficiency and achieve cost savings with streamlined and automated data collection, data import, analysis and reporting workflows.
  • Unlike other commercial environmental data management software packages, Hydro GeoAnalyst gives you complete control over your database, allowing you to fully customize the database structure to accommodate project needs and scale your database as data volumes grow.

Vital Information at Your Fingertips

  • The Query Builder is a powerful tool that helps you create, save and recall simple to complex data queries without having to know complicated SQL syntax. Easily define the conditions of your query by dragging and dropping database fields, and choosing the desired logical operators (AND, OR, LIKE and IS).

Gain critical insight

  • Gain greater insight into your environmental data with a suite of integrated analysis, interpretation and visualization tools including Map Manager, Cross Section Editor, Well Profile, Time Series Charts, Scene Viewer and more.
  • The analysis tools included with Hydro GeoAnalyst are developed solely by Waterloo Hydrogeologic which saves you money, guarantees interoperability, and simplifies procurement and license management.

Collaborate and Communicate Efficiently

Hydro GeoAnalyst stores all your data in a single, centralized database that can be accessed securely by multiple users across a network. Well Profiles, maps, cross-section diagrams, time-series charts and reports can be easily retrieved by team members and key decision makers.

  • Hydro GeoAnalyst streamlines field data collection with easy-to-use planning tools and support for mobile electronic data deliverables. Easily plan and schedule your field trips, and then conveniently collect your data using your Apple or Android mobile device.


What's New in Hydro GeoAnalyst 12.0 & Hydro GeoAnalyst PLUS

HGA 64-Bit Edition

The 64-Bit Edition of Hydro GeoAnalyst now covers all available functionality. New and updated 64-bit capable modules include:

  • Cross Section Viewer: Build custom expressions to evaluate and populate a desired sample field or parameter (see below).
  • Scene Viewer: Visualize datasets including boreholes, surfaces, maps, cross sections, and plumes in 3D.
  • 3D Interpolation: Interpolate 3D datasets into static or transient plumes that can be visualized and animated in the 3D Scene Viewer.

Cross Section Viewer

New 64-bit module Cross Section Viewer allows you to build cross sections more efficiently:

Cross Section Viewer Data Screen WHG

  • Define Cross Sections: Update older existing cross sections, pick from a list of stations to include in a new cross section, or define a cross section using the Map Viewer (see below)
  • Interpretations: define cross sections along the same transect based on interpretations of the geology, hydrogeology, and/or model layers
  • Auto-generate: automatically (re)build cross section interpretations based on intervals in applicable boreholes and intersecting cross sections
  • Edit: edit and refine cross section interpretations using a variety of tools, including digitizing, snapping, and splitting
  • Include Well Profiles: include custom well profiles for one or more boreholes along cross sections
  • Easy Migration: Automatically open existing cross sections developed in the legacy Cross Section Editor.

Map Viewer

The Map Viewer module has been enhanced to include:

Map Viewer cross-section Screen for HGA 12


  • Define Cross Sections:
    • digitize new lines or use an existing line to define new cross sections
    • add mapped boreholes within a specified buffer
    • add an optional surface to define topography along the cross section
  • Display Cross Sections: drag and drop cross sections onto the map to display the paths/transects of all cross sections in the project

Well Profile

The Well Profile Module has been enhanced to include:

Well Profile Plot Screen for HGA 12


  • Date Range for Water Levels: water level symbols can be limited to measurements within a specified date range
  • Hydrogeology Column: add an interval column for hydrogeology interpretations of the borehole intervals and/or show this interval in the well construction column.
  • Model Layers Column: add an interval column for model layer interpretations of the borehole intervals and/or show this interval in the well construction column.
  • Auto-generate Hydrogeology and Model intervals: specify a mapping between specific geologic layers and corresponding Hydrogeology and Model intervals and then autocomplete intervals for these tables for the active well or all wells in the active given station group.

Usability and Other Enhancements

HGA and HGA+ include the following additional enhancements:

  • Template Manager: new optional setting to force database tables and fields that are set to not be shown as hidden throughout the application, including in modules that typically show all fields, such as in the Query Builder and the Data Filter views
  • Print to PowerPoint Templates: the default Print to PowerPoint templates have been updated with a clean and consistent style.
  • User Feedback Buttons: quickly provide anonymous feedback using thumbs up/down buttons.
    Note: since the mechanism is anonymous, we will not be able to respond. Please reach out to our support team if you need a response

Integrated Geochemical Modeling (PHREEQC) (HGA+ only)

HGA Plus includes integrated cross-functionality with the basic features of PHREEQC, the popular geochemical modeling program developed by the USGS:

  • Thermodynamic Databases: Import thermodynamic databases into the project and map database species to project parameters
  • Saturation indices/Activities: Calculate the saturation indices and activities for one or more simples and seamlessly reimport the results into the project database, in a few button clicks
  • Basic Geochemical Modeling: Prepare basic geochemical models of one or more samples
    • Basic simulations include a streamlined graphical interface to include a variety of physicochemical processes occurring simultaneously or in a series of sequential steps, including:
      • Mixing
      • Changes in Temperature and/or Pressure,
      • Reversible and Irreversible Reactions, and
      • Phase Reactions such as:
        • Solution/dissolution with equilibrium phases,
        • Sorption/desorption via exchange assemblages,
        • Solution/Gas phase assemblages
      • The resulting PHREEQC input file can be run directly from within the HGA Plus interface and results can be imported into the database for further analysis and visualization, including plotting, mapping, and reporting.
      • The resulting PHREEQC input file can be supplemented with user-generated inputs, for scenarios where advanced users require some additional complexity.
    • Advanced Geochemical Modeling: Quickly and easily migrate samples to the PHREEQCi/PREEQC for windows interface in a few clicks, when more advanced modeling is required.
