Abstract: Coal waste piles pose significant risks to water quality, ecosystem health, and community well-being. In Ukraine’s Lviv–Volyn coal basin, the Chervonohrad concentrating plant’s waste pile exemplifies these challenges: unchecked physical processes can mobilise iron, contaminating groundwater and surface waters. No prior study has systematically linked precipitation to iron leaching in this context. This research creates and tests a predictive model relating precipitation to annual iron leaching from coal-mining waste. Laboratory column experiments on argillite flushed with deionised water under controlled flow generated empirical data for calibration. Using similarity theory (π-theorem) and regression analysis, we derived a simple linear relation for a unit spoil volume (1 Mm³): each additional millimetre of year precipitation mobilises 0.01 kg Fe∙Mm⁻³∙y⁻¹. Under the mean annual precipitation of 607.9 mm, the model indicates 24.8 kg Fe∙Mm⁻³∙y⁻¹; scaled to the Chervonohrad waste volume (48.89 Mm³), this equates to 1212 kg∙y⁻¹. Environmental and civil safety specialists and regulators, based on local precipitation data and the model we developed, can calculate seasonal or annual iron loading without large-scale field sampling. Civil protection agencies can likewise use these predictions for early warning and readiness during wet years. The approach developed by the authors is accurate, easy to apply, and can be used in other mining regions with similar climatic and geological conditions. It provides a compact rule-of-thumb for monitoring design, optimisation of containment and treatment, and policy-relevant thresholds to protect aquatic resources-bridging laboratory science and on-the-ground decision-making under changing precipitation patterns.
