Resumen

Abandoned mines and associated mine effluents, tailings ponds, and dumps pose a significant threat to human and environmental health and should be addressed as part of the environmental responsibilities of the mining industry. The objective of the study was to determine the extent to which the water of Quebrada Shinca (Peru) is contaminated with total metals and to outline possible applications in agriculture in the area. Water quality was monitored at three different times, using readings taken from seven environmental water monitoring points and three soil points, conducted in July, October 2022, and March 2023. The results are shown over the time intervals. The QISCA 03 (surface water) water flow is predicted to increase by 1603.04% from the reading taken in July 2022 to March 2023 and its values were below the Environmental Quality Standards for water (EQS), the QISCA 04 (mine effluent) flow reached (133.05%) and the values were (As=0.78, Cd=0.16, Cu=0.80, Zn=42.67) mg/l and for QISCA 07 (irrigation water) the flow increased by 92.42% and the values were (Cd=0.05, Mn=14.10, Pb=0.12 and Zn=13.94) mg/l in the same period.
