The present work had as objective to determine the concentration of lead in waters of the Chinchipe river impacted by the artisanal mining, San Ignacio - Cajamarca, La Libertad 2017, through a descriptive study of the concentration of lead in water; four samples were evaluated. These were subjected to a quantitative analysis by colorimetric method using a PF-12 Compact Photometer. In the quantitative determination the results were positive. In the quantitative determination of lead in surface waters in the four samples, we obtained averages of M1 (0.0125 mg / L), M2 (0.037 mg / L), M3 (0.034 mg / L) and M4 (0.02 mg / L); all these samples have concentrations within the permissible limits of lead in surface waters; which is 0.05 mg / L of surface water, compatible data according to the law established in SUPREME DECREE No. 015-2015-MINAN Category 2 for Rio de Janeiro, the provisions for the implementation of said standards were approved; That the national and international toxicity references considered in the approval of the National Environmental Quality Standards for Water have been modified, as evidenced by the research studies and international guidelines of the World Health Organization (WHO) of the Organization of the United Nations for Food and Agriculture (FAO)
