In my study of the highly mineralized mine-water storage impoundment in #SvystunovaGully , I used PHREEQC to quantify the equilibrium dissolution potential of calcite for every of >1000 groundwater sample collected over more than 10 years.

For each sample, I modeled how much calcite the water could dissolve if it encountered carbonate rocks along its flow path (SI = 0 at equilibrium). Each sample was treated as an independent thermodynamic system, and the resulting dissolution values were aggregated spatially using Voronoi polygons.

The map below shows the median Δmass of calcite (g/L) for each polygon.
Areas with more negative values represent water that remains capable of dissolving additional carbonate minerals — a long-term indicator of the water’s aggressiveness.

This approach highlights the zones where the aquifer is most vulnerable to carbonate dissolution around the mine-water pond.
