In the heart of Poland’s mining region, a recent study has unveiled critical insights into groundwater quality, particularly at the Żelatowa intake in Chrzanów. Conducted by a team led by Katarzyna Wawrzonek from AGH University of Krakow, the research highlights the intricate relationship between mining activities and the sustainability of local drinking water supplies.
As the demand for clean drinking water intensifies globally, understanding the implications of anthropogenic influences on groundwater becomes ever more crucial. Wawrzonek notes, “Our findings indicate that while mining operations have historically compromised water quality, there is a potential for recovery and management through careful monitoring and intervention.” This statement underscores a dual narrative: the challenges posed by mining and the opportunities for sustainable water management.
The study meticulously analyzed data from three deep wells, S1, S2, and S3, over several years. Results showed concerning trends, particularly in well S2, where parameters such as electrical conductivity and concentrations of iron and manganese were found to exceed acceptable limits as per the European Union’s drinking water directive. The implications are significant for local water supply systems, which are already grappling with scaling and corrosion issues linked to these adverse changes.
Wawrzonek’s team employed the PHREEQC software, a powerful tool for predicting chemical interactions in water, to devise strategies for blending well water to meet safety standards. “By mixing the water from different wells, we can ensure a safer supply for the community,” she explained. This approach not only addresses immediate quality concerns but also paves the way for innovative solutions in water treatment and management.
The commercial ramifications of this research are profound. Water utilities, particularly those operating in mining-affected areas, may need to reassess their water sourcing strategies. The findings could drive investments in monitoring technologies and advanced treatment systems, ensuring compliance with regulations while safeguarding public health. Moreover, as communities increasingly demand transparency and safety in their water supplies, utilities that adopt proactive measures may enhance their reputation and customer trust.
The study published in ‘Water Resources and Industry’ (translated from Polish) serves as a wake-up call for stakeholders in the water, sanitation, and drainage sector. It emphasizes the necessity of integrating hydrogeological and hydrogeochemical perspectives into resource management, especially in regions where mining activities pose significant risks.

As the water industry continues to navigate the challenges of pollution and resource depletion, the lessons drawn from the Żelatowa intake case study could very well shape future practices in groundwater management and water quality assurance.
