The Chinchillas Project is a silver-lead-zinc mine, with an approximate volume of 53 million tons (mineralized plus sterile waste). It will be developed through traditional production methods and will have three associated waste dumps, where the sterile waste will be deposited.
Knight Piésold was responsible for surface water and groundwater monitoring that involved examining analytical results and preparing monitoring reports. This included measuring river flow rate, giving continuity to environmental baseline studies.
Water quality for surface water, groundwater, and outflow was monitored on a monthly basis and analyzed using parameters according to Act No. 24,585, which were the same parameters used for previous baseline monitoring studies. Knight Piésold presented four quarterly reports, covering all seasons (spring, summer, fall, and winter), in addition to an annual report.
Additionally, Knight Piésold conducted an analysis using Stiff and Piper diagrams for the monitoring points to provide a hydrochemical description of the water quality. Piper diagrams will also be developed for each monitoring point in order to know the hydrochemical evolution of the area's water resources over time.
