“Importance of Water Quality in Mining Areas and its Relation to Mining Activity According to Supreme Decree No. 004-2017-MINAM”. Introduction: Mining is vital for the global economy, but it can negatively impact water quality. Managing water quality in mining areas is crucial due to its environmental and human health impacts. Supreme Decree N° 004-2017-MINAM regulates physicochemical parameters of water used in mining. Hydrogeochemical studies are essential to evaluate and control water contamination. Objective: Examine water quality in mining areas, its link to mining, and compliance with regulations for environmental and human health. Methods: In situ measurements were conducted to determine electrical conductivity, pH, total dissolved solids (TDS), salinity, and temperature. Additionally, the Gibbs Diagram was utilized to analyze dissolved solids concentration and associated processes. Results: The results show that the values of electrical conductivity, pH, total dissolved solids, salinity, and temperature remain within established standards. The Gibbs Diagram reveals processes of solid concentration due to evaporation. Conclusion: Analyzing groundwater in mining areas is vital for water quality management. Results meet standards, ensuring safe water and environmental protection.
