Description:	Mining use and produce large amounts of hazardous substances that often reach surface waters streams. Sonora, been a Mexican state with very large active and inactive mines located near the rivers, presents a high potential for contamination of its water surface bodies. The purpose of this study was to identify those mines with more possibilities to contaminate the surface water currents of the South-Sonora hydrological region using a modification of the EPA’s methodology to carry out Preliminary Risk Assessment (EPA,1991). The mines that represent higher risks were: 1) in the Sonora River Basin, “Buenavista del Cobre”, “Cerro Prieto”, “Mercedes”, “Santa Elena” and the inactive mine “Amelia”; 2) In the Yaqui River Basin are “La India”, “Mulatos”, “La Bonancita”, “Luz del Cobre”, “La Caridad” and the abandoned mines “Pilares” and “Cumobabi”. La actividad minera genera enormes cantidades de materiales peligrosos que suelen llegar a aguas superficiales. Sonora, al poseer grandes minas activas e inactivas a las cercanías de ríos, presenta un riesgo potencial de contaminación en sus corrientes superficiales. El objetivo del presente estudio fue identificar las minas que pudieran presentar un mayor riesgo de contaminación a las corrientes superficiales de la Región Hidrológica Sonora-Sur utilizando una modificación de la metodología de la EPA (1991) para realizar evaluaciones preliminares de riesgo. Las minas identificadas con mayor riesgo fueron 1) En la cuenca Río Sonora, Buenavista del Cobre, Cerro Prieto, Mercedes, Santa Elena, y la mina inactiva Amelia, 2) En la cuenca Río Yaqui: La India, Mulatos, La Bonancita, La Caridad, Luz del Cobre y las minas inactivas Pilares y Cumobabi.
