  • How to Model Time-Varying Liner Failure in POLLUTE

    Landfill liner systems are designed to delay or prevent contaminant migration—but they don’t last forever. Over time, geomembranes degrade, defects grow, and hydraulic properties change. For environmental consultants, the real challenge isn’t just modeling contaminant transport—it’s accurately simulating how liner performance evolves over decades. This is where POLLUTE stands out. Unlike many traditional models, it…

  • How to Build a Breakthrough Curve for Contaminant Transport

    Breakthrough curves are one of the most powerful tools in contaminant hydrogeology. Whether you’re assessing landfill leachate migration, evaluating remediation performance, or modeling groundwater contamination, a well-constructed breakthrough curve provides clear insight into how contaminants move through subsurface systems over time. In 2026, the process goes beyond spreadsheets. With advanced tools like POLLUTE and MIGRATE,…

  • How to Reduce Borehole Logging Time by 70% Using Digital Workflows (2026 Guide)

    Borehole logging has long been one of the most time-intensive tasks in environmental and geotechnical consulting. Between handwritten field notes, spreadsheet transcription, log drafting, and report formatting, it’s common for projects to spend more time processing data than actually collecting it. But leading firms are changing that. By implementing fully digital workflows—especially using tools like…

  • MIGRATEv10 vs POLLUTEv10: Fractured Layer with Sorption Comparison

    Overview This example compares results from MIGRATEv10 and POLLUTEv10 for a fractured soil layer with sorption. This is one of the more complex transport scenarios, combining: The result is a system where contaminants can move rapidly through fractures while simultaneously being retarded and stored in the soil matrix. Model Setup Both models simulate a two-layer…

  • MIGRATEv10 vs POLLUTEv10: Finite Mass Source Comparison

    Overview This example compares finite mass transport results from MIGRATEv10 and POLLUTEv10. Unlike constant source cases, this scenario represents a limited contaminant inventory, where concentrations rise, peak, and then decline as the source is depleted. The key objective is to evaluate how both models predict: Model Setup Both models use identical physical conditions: This configuration…

  • MIGRATEv10 vs POLLUTEv10: Pure Diffusion Comparison

    Overview In this example, we compare pure diffusion results generated using MIGRATEv10 and POLLUTEv10 under identical conditions. The objective is to verify consistency between the two models and highlight key differences in their capabilities. Both simulations consider contaminant transport through a 4 m thick layer under pure diffusion (no advection), with constant concentration boundary conditions…
