🌎 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.

🔬 Metasomatic Zonation as a Model of Groundwater Contamination

One of the key theoretical bases in my research is the classical metasomatic zonation model (Korzhinskii, 1960s).

I interpret the contamination halo formed by mine waters not as passive dispersion — but as an active metasomatic system, where aggressive fluids drive alteration and re-precipitation reactions within the carbonate aquifer.

Highly mineralized mine waters create a complex interaction front.
Thermodynamic modeling (based on well-monitoring data) allows identification of several geochemical zones partly analogous to Korzhinskii’s metasomatic sequence.
