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

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 9.0 & Hydro GeoAnalyst PLUS

Plot Module

HGA 9.0 now has an enhanced plotting module capable of generating a variety of plots to help you better understand your data:

  • Statistical Plots: Box and Whisker, Histogram, Probability, Quantile, Detection Summary
  • General Plots: Scatter, Line, Pie, Stacked Bars, Radial, Time Series

*This new module helps you create powerful presentations using single plots or collections of related plots that draw attention to important items you want to highlight.

HGA+ takes this enhanced plotting module a step further with tools to assess geochemical data and to make the information dynamic and interactive.

  • Geochemical plots: Piper, Stiff, Durov, Schoeller, Wilcox, Giggenbach, Meteoric Water Line, Ludwig-Langelier, Ternary.
  • Interactive/Dynamic data: When users click on data points in a plot, the corresponding samples are highlighted in the sample list. Similarly, when users select samples from the Sample list, they will be highlighted on any plots in which they appear. This is useful for working with data to identify outliers or highlight interesting items.
  • Query driven: With the addition of compound queries, even more meaningful plots can be built based on easy-to-create static and dynamic sample sets and station groups.

Interactive Plots

Query Builder

HGA 9.0 offers increased access to user data, and can pull the information easily to use in presentation and reports:

Compound Queries: Build Queries with nested conditions which helps to pinpoint the exact data you need to work with across multiple tables.


Water Quality Analysis

HGA+ comes with a comprehensive set of functions and converters allowing users to perform quick, on-the-fly analyses on water quality data. HGA+ is capable of the following calculations and conversions:

  • Unit Conversion: HGA+ manages measurement and concentration units – switch between mass-, molar-, and equivalent-based concentrations on the fly
  • Ionic Functions: Water Type, Electroneutrality/Ion Balance, Sum of Anions, Sum of Cations, TDS, Hardness, Alkalinity
  • General: Date functions, Exceedance counts, Total Organic Carbon, Total Organic Halogens
  • Corrosion and Scaling Indices: Langelier Saturation, Ryznar Stability, Puckorius Scaling, and Larson-Skold
  • Agricultural Irrigation Metrics: Sodium Adsorption Ratio, Magnesium Hazard, Residual Sodium Carbonate
  • Enthalpy: Enthalpy of water (liquid or vapor) based on temperature or dissolved silica
  • Isotopes: Estimates of infiltration elevation and temperature based on Oxygen-18 and Deuterium isotopic fractionation

Reporting Tools

Quickly generate powerful reports and presentations with HGA 9.0:

  • Macro-Enabled Reports: Print-to-Office Templates support macro-enabled documents (.docm, .xlsm, .pptm) so users can build advanced reporting features

HGA + Sample Report: HGA+ allows users to build standardized sample summary reports that calculate statistics, including min/max, specified quantiles, and the mean.  Reports have the option to compare results to active Water Quality Standards.

Scripting with R-Console

HGA+ includes a console that allows users to use the R scripting language and leverage the thousands of available libraries it offers for data analyses, visualization, categorization and much more.

Improved Usability

Parameter Editor: Create lists of parameters based on a field in the sample analysis table. When importing new data users can choose to add new parameters based on this field – this greatly improves automating parameter management.

List Editor: Create and add to lists in the List Editor and Template Manager based on values in present in a specified field, and update the list when importing new values

SQL Server Versions: Support for databases stored in SQL Server 2012, 2014, 2016, 2017, and 2019
