🌎 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.

Two figures below show the modeled distribution of cadmium species across the aquifer and their evolution with dilution
