💧 Aggressive groundwater and the long memory of contamination
Even after more than a decade of monitoring, the groundwater in this carbonate aquifer remains undersaturated with respect to calcite — consistently showing negative SI values across nearly all observation wells.
This means that the system is still chemically aggressive toward limestone, slowly dissolving the host rock.
The impoundment, operating since 1976, continues to influence the aquifer — with the geometry of possible subsurface voids still uncertain to this day.📘 All supporting data and modeling results are included in the draft monograph:

🌎 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

🔬 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.📊 The image shows my preliminary zoning concept.
📘 All calculations and hypotheses are detailed in the draft monograph:

#IronAir Batteries Are Here. They May Alter the Future of Energy.
Battery tech is now entering the Iron Age.
By Darren Orf
Published: Jan 17, 2023"Each iron-air battery is about the size of a washer/dryer set and holds 50 iron-air cells, which are then surrounded by an electrolyte (similar to the Duracell in your TV remote). Using a principle called 'reverse rusting,' the cells 'breathe' in air, which transforms the iron into iron oxide (aka rust) and produces energy. To charge it back up, a current reverses the oxidation and turns the cells back into iron.
"NASA first started experimenting with iron-air batteries back in the late 1960s, and it’s obvious why this next-gen storage system has engineers excited. For one, iron-air batteries solve a few of lithium’s biggest shortcomings right off the bat. As their name suggests, these batteries use primarily #iron, the fourth most abundant element on Earth, and ... well ... air. This tech’s adoption could help curtail the large amounts of water used to mine #lithium (not to mention alleviating the potential for #GroundwaterContamination
"Secondly, and most importantly, iron-air batteries would be 10 times cheaper, perform better, and last 17 times longer. Right now, these batteries’ primary task would be to bridge the gap when utilities need more power during peak hours, and as green energy eats up a bigger share of the energy pie, they could also crucially store excess energy on sunny days to shore up supply when the clouds roll in. Lithium-ion only provides approximately four hours of storage, whereas iron-air could deliver up to 100 hours—a full four days to bridge those energy gaps.
"The downsides to iron-air batteries? They’re big and also slow to recharge, which is likely why lithium-ion will remain the battery of choice for electric cars and smartphones. #FormEnergy also says these iron-air batteries will form 'power blocks' where iron-air batteries handle long load times, while lithium-ion batteries take care of spikes in demand."
