💧 Beyond Diffusion: Groundwater as a Rock–Fluid System

Contaminant plumes in groundwater are often seen as passive — just diffusion and advection through porous media.
But what if we treat them as active geochemical fronts instead?

In my recent modeling work, I describe contamination not as a mechanical process, but as a metasomatic transformation — a reaction zone between aggressive mine waters and carbonate aquifers.

Each sector of the aquifer develops its own thermodynamic balance and mineral stability field.
The plume itself becomes a chemical engine — reshaping host rocks, opening new pathways, and shifting the entire water–rock equilibrium.

🌎 Mapping dominant chemical speciation in a polluted carbonate aquifer

In my recent modeling work, I modeled the dominant forms of element speciation in groundwater within a carbonate system.

Beyond pure geochemical curiosity, this approach provides a practical lens:
– it reveals where mineral precipitation is most probable,
– and helps identify zones where remediation can be most effective.

💻 Combining thermodynamic modeling (PHREEQC) with spatial analysis in R and QGIS turns subsurface processes into actionable insights for water-quality management and contamination mitigation.
