POLLUTEv10 Example 17: Modeling a Landfill with Composite Liners and Dual Leachate Collection Systems
Introduction POLLUTEv10 Example 17 demonstrates how to model a landfill incorporating a composite primary liner, primary and secondary leachate collection systems, and a compacted clay secondary liner. This example introduces a more engineered and realistic landfill design, reflecting modern containment practices. A key feature is the use of the Giroud et al. (1992) leakage method,…

POLLUTEv10 Example 18: Modeling Phase Change in a Secondary Leachate Collection System
Introduction POLLUTEv10 Example 18 demonstrates the application of the Phase Change special feature to simulate contaminant transport within a landfill system that includes a secondary leachate collection system (SLCS). This example is particularly valuable for environmental engineers and hydrogeologists interested in modeling multi-phase contaminant behavior across unsaturated and saturated zones. The scenario focuses on the…

POLLUTEv10 Example 19: Multiphase Diffusion of Toluene Through a Geomembrane System
Introduction POLLUTEv10 Example 19 models a multiphase diffusion experiment originally conducted by Buss et al. (1995). This example is particularly useful for understanding how volatile organic compounds (VOCs), such as toluene, migrate through engineered barrier systems that include geomembranes, airspaces, and aqueous reservoirs. The simulation demonstrates how POLLUTEv10 can accurately reproduce laboratory-scale results by incorporating…

POLLUTEv10 Example 20: Sensitivity Analysis of Primary Leachate Collection System Failure
Introduction POLLUTEv10 Example 20 introduces Sensitivity Analysis as a powerful tool to evaluate how uncertainty in system performance impacts contaminant transport. In this case, the focus is on the service life of a Primary Leachate Collection System (PLCS) and how variations in its failure timing influence contaminant migration. Building on the framework established in Examples…

Why We Built GaeaSynergy: Solving the Fragmented Data Problem
Introduction In the world of geotechnical engineering, environmental consulting, and geological investigation, data is everything. Every borehole log, lab result, cross-section, and field observation contributes to a deeper understanding of the subsurface. Yet for decades, one persistent challenge has limited the full potential of this data: Fragmentation. Data scattered across spreadsheets, disconnected software tools, legacy…

Inside GaeaSynergy: How We Designed a Platform for Engineers, Not Just Data
Introduction In the world of geotechnical engineering, environmental consulting, and geological analysis, software has traditionally been built around data structures, not people. Tables, schemas, and databases often take center stage, while the real users—engineers and geoscientists—are left adapting their workflows to fit rigid systems. At GAEA Technologies, we saw this disconnect firsthand. Engineers weren’t struggling…

Installation of Monitoring Wells for a Phase II ESA
Introduction Installation of monitoring wells is one of the most critical steps in a Phase II Environmental Site Assessment (ESA), particularly when groundwater contamination is suspected or confirmed. These wells provide direct, repeatable access to subsurface conditions, allowing environmental professionals to evaluate groundwater quality, determine contaminant distribution, and assess hydrogeological conditions over time. Unlike soil…

Reporting and Recommendations for a Phase II Environmental Site Assessment (ESA)
The reporting and recommendations stage of a Phase II Environmental Site Assessment (ESA) represents the culmination of all investigative work. It is where raw field data, laboratory results, and professional interpretation are synthesized into a defensible, decision-making document. This final report not only communicates findings but also establishes the environmental status of a property and…

Laboratory Analysis and Data Interpretation for a Phase II ESA
Laboratory analysis and data interpretation represent the culmination of a Phase II Environmental Site Assessment (ESA). After weeks of planning, drilling, and careful sample handling, it is the laboratory results—and how they are interpreted—that ultimately determine whether a site is contaminated and what actions are required next. These stages transform physical soil and groundwater samples…
