Message from the President

As summer comes to a close, we’re looking ahead to an exciting fall. We’re currently hiring for a Modeller/GIS Specialist role. This position offers the chance to work on impactful projects at Aquanty.

Whether you’re a new graduate or bring up to 10 years of experience, we’d love to hear from you— so please share with anyone who may be a good fit.

Also, next month Aquanty will be attending the 2025 Water Canada Awards in Toronto. We're proud to highlight that HydroSphereAI and our close collaborators at the Manitoba Forage and Grassland Association (MFGA) have been named finalists in two categories: 1) New Tech Award and 2) Early Adopter/Innovation Partnership Award.

These awards celebrate innovation and leadership in water across Canada, and it’s an honour to have both our technology and partnerships recognized. We’re excited to see HydroSphereAI and the MFGA collaboration acknowledged for their role in advancing sustainable water management, and we look forward to celebrating with peers who are helping shape the future of Canada’s water sector.

Finally, don’t miss the latest research highlights featured below. These studies continue to demonstrate how HydroGeoSphere is driving forward integrated water science and supporting real-world applications.

Thank you for staying connected with us, and we look forward to sharing more updates as we head into October.

- Steve Berg, President & CEO, Aquanty Inc.

Quantifying the potential of using Soil Moisture Active Passive (SMAP) soil moisture variability to predict subsurface water dynamics

We’re pleased to highlight this publication co-authored by several Aquanty staff including Steven K. Frey, Bruce Xu, Omar Khader, Andre R. Erler, and Edward A. Sudicky, which investigates the potential for using near-surface soil moisture measurements from the Soil Moisture Active Passive (SMAP) satellite system to predict subsurface soil moisture and groundwater storage dynamics. This research offers valuable insights into how satellite-based soil moisture data can inform large-scale hydrological modelling and support improved water resource management.

Estimating cumulative wastewater treatment plant discharge influences on acesulfame and Escherichia coli in a highly impacted watershed with a fully-integrated modelling approach

In this research highlight, researchers used HydroGeoSphere (HGS) to explore the impact of wastewater treatment plant (WWTP) discharge on surface water contamination in a mixed-use watershed in Ontario, Canada. The study focused on tracking acesulfame, a commonly used artificial sweetener, and Escherichia coli (E. coli), a fecal indicator, to understand how these contaminants move between surface and groundwater systems. Understanding the interactions between surface water and groundwater is critical in watersheds where WWTP discharge contributes to regional water quality concerns.

Is the Water Balance of Your Waste Rock Pile Reliable? A framework for Improving Assessment of Water Inputs and Outputs for a Typical Storage Facility

We’re pleased to highlight this research by Craig Thompson, Randi Thompson, and Willy Zawadzki of BGC Engineering, which presents a practical framework using HydroGeoSphere modelling to improve water balance assessments in mining waste rock piles. This research was presented at the International Mine Water Association (IMWA) 2025 conference. With increasing pile heights, evolving geochemical considerations, and growing scrutiny around drainage and treatment, the study highlights the importance of simulating how waste rock emplacements evolve over time and how that evolution impacts water movement and seepage predictions.

New PhD Opportunity: Characterizing Subsurface Water Storage Across Canada’s Interior Plains

We’re excited to share a PhD opportunity that builds on work from the Canada1Water initiative. Hosted at the University of Alberta's Watershed Science & Modelling Laboratory (WSML), this research will use HydroGeoSphere (HGS) to work with a basin-scale model of the Nelson River Basin to investigate subsurface water storage dynamics through the middle and end of the 21st century. This interdisciplinary project will support Canada’s growing need for advanced water modelling tools that link soil moisture, groundwater, and surface water under changing climate conditions.

HGS Software Release

Find our monthly HGS software update on our 'HGS Downloads' page, the September 2025 monthly software update is now available. This release delivers targeted bug fixes, improved error handling and expanded hgs2vtu output options, along with new tools for polygon tracking and water balance reporting.

Key updates include:
• Fix for polygon tracking Tecplot output where duplicate nodes were reported
• Corrections in unsaturated brooks-corey functions and unsaturated van genuchten functions commands in grok files
• Transport mass balance fix for solute exchange variables (PM2Olf(Disp), Dual2Olf(Disp), PM2Frac(Disp))
• Improved error handling for cleaner termination outputs
• hgs2vtu enhancements: fixed solute naming bug, reorganized --help output, added new commands (--initial-time, --cum-water-balance-csv, --cum-water-balance-tecplot)
• New polygon tracking functionality for defining fluid mass balance from shapefile polygons
• Updated Reference Manual with documentation for all new commands

As always, we are committed to the continued improvement to the user experience. Do you have suggestions for new commands or improvements to the user experience? Send your ideas to [email protected]!
