Identification and quantification of metals in water for human consumption in the Lircay-Angaraes-Huancavelica district 2015

Abstract

This investigation was carried out during 2015 in the Lircay district, Angaraes province, Huancavelica department. It formulated the problem about how many metals and in what concentrations exist in the water for human consumption in three reservoirs of this. The general objective was precisely to identify and quantify the metals in water for human consumption in these reservoirs. The theoretical framework was carried out with topics of importance at the international, national and local levels. To carry out the samplings, the water sampling protocol was respected. In this way, the samples were taken in the Ato stream (M1), which leads to the reservoir of the same name; This distributes to the networks of the houses of Pueblo Viejo, Pueblo Nuevo and the Santa Rosa neighborhood. So also in the Ahuay stream (M2), which leads to the Virgen del Carmen reservoir, supplier of the neighborhood called the same, and in the Sicra river (M3), which leads to the Aylana reservoir, distributor of the Bellavista neighborhood. The samples taken in total were six, of which, as a result, 21 metallic elements were obtained (Al, As, B, Ba, Be, Cd, Co, Cr, Cu, Fe, Li, Mg, Mn, Mo, Na , Ni, Pb, Sb, Se, V and Zn). Said samples were analyzed in the laboratory of the General Health Directorate (DIGESA) with the spectrophotometer equipment (ICP-OES). The concentrations are between the parameters of 0.001 mg / L minimum and 9.4434 mg / L maximum; the concentration on average is below the regulations for Water for Consumption (AC), Natural Water (AN) Category 1, Natural Water (AN) Category 4 and AN Category 3, of which Fe, As, Cu and Pb are find above the maximum allowable limits. Zn and Cd are below the maximum permissible limits, so the hypothesis is validated.
