Hydro GeoAnalyst Plus 14 (Environmental Data & 3D Design)

Overview of Hydro GeoAnalyst Plus 14

Hydro GeoAnalyst Plus is a comprehensive environmental data management system built for hydrogeologists, geochemists, and environmental engineers. Unlike generic spreadsheet tools, HGA+ stores all project data in a centralized Microsoft SQL Server database, allowing multiple users to collaborate securely while maintaining full data integrity.

The “Plus” edition extends the standard HGA feature set with AquaChem’s geochemical capabilities, a PHREEQC interface, and an R-Console module for statistical computing. Version 14 specifically targets three operational pain points: remote collaboration, high-volume data ingestion, and automated statistical interpretation.

Key Features of Hydro GeoAnalyst Plus 14

Environmental Data Management

• Centralized SQL database – All borehole logs, water quality samples, lithology records, and monitoring station data reside in one relational structure.

• Template Manager – Pre-built environmental database templates aligned with common regulatory data models.

• Query Builder – Drag-and-drop interface for constructing complex SQL queries without writing code.

Geochemistry and Modeling (HGA+ Exclusive)

• PHREEQC integration – Calculate saturation indices, activities, and basic geochemical models directly from sample data.

• R-Console – Execute R scripts for custom statistical analysis, visualization, and data transformation.

• AquaChem geochemical tools – Piper, Durov, Stiff, and Wilcox diagram generation with built-in water quality standards.

Visualization and Reporting

• Map Manager – GIS-based mapping with interpolation and spatial querying.

• Cross-Section Editor – Build geological cross-sections from borehole data.

• 3D Scene Viewer – Site conceptual model visualization in three dimensions.

• Time Series and Scatter Plots – Now with automatic linear regression lines and customizable symbol groups.

What’s New in Hydro GeoAnalyst Plus 14

Cloud Database Support

New HGA projects can store their database in the cloud. Team members with an internet connection can access the same project from any location. Compatible with AWS, Azure, Google Cloud, or a self-hosted web server.

Bulk Data Import

How to Use Hydro GeoAnalyst Plus 14

Creating a New Project

1. Launch HGA+ and select File > New Project.

2. Choose Local Database for single-user work or SQL Server for team projects.

3. Select an environmental database template (e.g., EPA Regions 2 & 5).

4. Define station groups, parameters, and sample sets.

Importing Data

• Single import: Use EDD Workflow or direct table entry.

• Bulk import: Select Bulk Data Import, map fields once, and select multiple source files.

• Review the import log for rejected rows and correct format issues.

Running Trend Analysis (HGA+)

1. Open the Trend Analysis module from the HGA+ menu.

2. Select the time-series parameter and monitoring station.

3. Choose one or more statistical tests (Mann-Kendall, Sen’s slope, etc.).

4. Run the analysis.

5. Export results to Excel or generate a trend plot.

Generating Reports

• Use Sample Reports to export modeled and calculated parameters.

• Export water quality standards directly to spreadsheet format.

• Use Print-to-Office templates for formatted Word or Excel deliverables.

Best Use Cases

Groundwater Monitoring Networks

Manage long-term water level and water quality data across multiple wells. Apply Mann-Kendall trend tests to detect declining aquifer conditions.

Contaminated Site Assessment

Store and query analytical results from soil, groundwater, and soil vapor sampling. Generate cross-sections and 3D plume visualizations for regulatory reporting.

Mining and Mineral Exploration

Analyze borehole data from exploration programs. Integrate lithology, assay, and geochemical results into a single database.

Landfill and Remediation Projects

Track leachate chemistry, gas monitoring data, and remediation performance metrics over time. Compare stations using the new Compare Tool.

Regulatory Compliance Reporting

Export water quality standards, sample metadata, and trend statistics for EPA or state-level reporting requirements.

Advantages and Limitations

Advantages

• Single source of truth – One SQL database eliminates version conflicts and spreadsheet errors.

• Regulatory alignment – Templates match common environmental data models.

• Scalability – From a single laptop to a multi-user cloud deployment.

• Integrated geochemistry – PHREEQC and AquaChem tools avoid data export/import cycles.

• Reproducible statistics – Trend Analysis module produces auditable, exportable results.

Limitations

• Windows only – No macOS or Linux native version.

• SQL knowledge helpful – While the Query Builder abstracts SQL, advanced database administration still requires SQL Server familiarity.

• License cost – Commercial licensing may be prohibitive for small consultancies.

• Learning curve – The breadth of modules requires structured training to use effectively.

• Internet dependency for cloud – Cloud database access requires reliable connectivity.
