Wetstone Solutions
Fate and transport modeling
Models should make your assumptions visible. We document the conceptual model, grid, boundaries, and calibration, then show which levers actually move the prediction.
At a glance
Fate and transport modeling at Wetstone Solutions couples groundwater flow simulation with contaminant transport, with documented assumptions, calibration to site data, and sensitivity on the drivers of the answer.
Who this is for
Teams that need defensible predictions for remedy design, natural attenuation, pathway analysis, allocation, or rebuttal of an opposing model.
Methodology
Conceptual model first, then discretization and parameters tied to observations. Calibration targets and sensitivity runs are reported so others can reproduce the logic—not just admire the color maps.
Deliverables
- Model development and calibration reports
- Scenario analysis for remedy or allocation questions
- Peer review and rebuttal support
- Exhibits and demonstratives for hearings
Frequently asked questions
- What is fate and transport modeling?
- It combines groundwater flow simulation with contaminant transport processes (advection, dispersion, sorption, decay) to estimate concentrations through space and time under stated assumptions.
- What makes a groundwater model defensible?
- Transparent assumptions, calibration to independent data, sensitivity analysis, and consistency with the conceptual site model. Opacity and hidden parameter tuning undermine credibility.
- Can you work with an existing model prepared by another firm?
- Yes. We can rebuild, recalibrate, or independently verify workflows and inputs, depending on what records and files are available.
- Do you use both analytical and numerical approaches?
- Yes. The appropriate tool depends on complexity, data density, and the decision being supported. We match method complexity to the question—not the other way around.
