Thermodynamic Modeling & Policy Relevance

As regulatory discussions and technical feasibility studies for the Svystunova Gully mine-water retention system (2026–2027 period) get underway, integrating rigorous thermodynamic modeling into the engineering baseline is critical.

Simple dilution metrics do not account for mass-balance limits, bedrock dissolution, concrete leaching, or secondary mineral precipitation along the waterway. Following today’s session of the government interdepartmental working group, I submitted key findings from my open-access research to support evidence-based decisions. The submitted package includes speciation models, phase equilibria calculations, and reactive transport assessments focused on mining wastewater management and dam stability evaluation.

🧪 Bridging Hydrochemistry, Thermodynamic Modeling & GIS: A Relational Schema

🗂️ Hydrogeochemical workflows are often fragmented across spreadsheets, standalone PHREEQC runs, and GIS layers, creating transfer errors and scaling friction.

⚙️ To build a reproducible pipeline, I structured a relational schema connecting raw chemistry, thermodynamic speciation, and spatial topology:
🔑 Relational Keys: Linked via Solution ID and Sampling Location to preserve data integrity across all stages.
⚛️ Automated Speciation: Raw ionic assays are ingested into PHREEQC to computation.
🗺️ Spatial Binding: Speciation outputs join spatial geometries in R (sf and terra packages) for contaminant plume mapping and cross-sections.

📖 Full methodology and regional case studies are detailed in my open-access monograph on mineralized groundwater plume.

Added 25 mg/L Silicon (Si) and 5 mg/L Aluminium (Al) to the hydrogeochemical baseline of the Svystunova Gully mine water impoundment, modeling clay mineral phase equilibria using RedModRphree + PHREEQC (Thermoddem database, T = 12°C).

Key thermodynamic outcome (pe–pH diagrams across pH 2–10):
The solid-phase stability field is completely dominated by Beidellite(Na) and acidic forms of montmorillonite (Hmontmorillonite).

🛠 What does an end-to-end open-source stack look like for an independent hydrogeochemical monograph?

Doing full-cycle research—from thermodynamic calculations to print-ready LaTeX typesetting—requires a synchronized toolkit. Here is the exact stack:

🧪 Thermodynamics & Analytics:
• #PHREEQC 3.7.3 for aqueous speciation&equilibrium modeling.
• #Rstats Stack: RedModRphree, ggtern, sf/terra, tidyverse (ETL).

🗺 GIS & Literature Search:
• #QGIS for spatial alignment & cartography.
• #Recoll for local full-text search across reference databases.

📚 Typesetting & Reproducibility:
• #LaTeX2e + #TeXStudio + #JabRef for typography & #BibTeX references.
• xtable for automated R-to-LaTeX data exporting.
• #Debian Linux as a main engine.

💡 Takeaway: Zero proprietary software licenses needed. Complete reproducibility from raw analytical data to a print-ready PDF.

📌 Thematic hashtags I use in my Mastodon posts

To help readers navigate the different topics I work on, I use several specialized hashtags.
Here is a short overview of each one:

🌎 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

💧 Exploring how contaminated mine waters behave in a carbonate aquifer — through the lens of metasomatic zoning and thermodynamic #geochemical modeling.

Using #PHREEQC simulations, data analysis in #RStats, and geospatial visualization in #QGIS, I’m studying how mine drainage transforms groundwater systems and mineral equilibria over time.

📘 The draft version (v0.75) of my monograph on this topic has already been downloaded 550+ times on #Zenodo — showing how relevant this issue has become for both science and environmental policy.

It’s independent research that links theory, modeling, and practical hydrogeochemical assessment — focused on the long-term impact of mine waters in the Kryvyi Rih region.
