How reliable are dilution estimates in contaminated aquifers?

In my current monograph, I validated the dilution coefficient using two fully independent approaches:
- chloride concentrations as a conservative tracer
- solution density calculated in PHREEQC (Laliberté–Cooper model)

I then performed a robust statistical comparison of both dilution estimates (n ≈ 2000).
The result: no statistically significant difference between the two methods (Mann–Whitney test), with very close median values and negligible effect size.

❗What does this mean in practice?
It confirms that density-based calculations — often ignored in groundwater contamination studies — provide robust, independent validation of classical tracer-based approaches.
This is especially important for highly mineralized mine waters, where density-driven processes (e.g. buoyancy effects, Rayleigh–Taylor instability) can critically affect plume behavior.

Based on the metasomatic (thermodynamic) zonation of the groundwater contamination plume identified in my study, I prepared a schematic impact map.

Unlike conventional chloride concentration isolines (which are often weakly informative), this approach reflects the thermodynamic state of the aquifer. The map clearly shows that the aggressive corrosion-by-mixing zone (Subzone III) occupies a large area and, in several places, extends beyond the existing monitoring well network.

This indicates that the current monitoring system is insufficient to delineate the full zone of influence of the mine water impoundment.

The criteria for defining metasomatic subzones and the associated risks are described in detail in the current published version of my monograph:

Looks like I’ve created something that people actually find interesting.

But here’s the real question: with a daily rate of 30–40 downloads... what are the odds of catching such a perfectly round number by accident? 🤣

(Maybe the Universe has a soft spot for hydrogeochemistry!) 😁

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.
