This document reports on the second follow-up of the Diablo Mudo Exploration Project undertaken by the Compania Minera Raura S.A. located in the Cordillera Huayhuash Reserved Zone. Three principal findings were presented in the report: at three monitoring stations the measures of pH and Zinc (Zn) were above the Maximum Permissible Limits for mining activity (D.S. 010-2010-MINAM); at several monitoring stations the measures for pH, aluminium (Al), cadmium (Cd), manganese (Mn), nickel (Ni), lead (Pb) y zinc (Zn) were above the national standards for drinking water (category 1 D.S. 002-2008-MINAM); at the possible spill site there is a greasy substance that appears to be diesel based on smell and taste.
