Description:In Guatemala 90 % of urban water has a rural origin and 70% of the sources are superficial. We selected three rivers of the upper basin of Sis Icán (Chita, and Sacobá Ixconá-Sis; Pacific coast) to asses drinking water. The watersheds have agriculture and livestock farms, as well as urban and rural populations. Water quality was assessed in the origin and end of each river, in 2012. The variables measured were: NO3, NO2 =, SO4 =, Fe, Cl, Mn, hardness, total coliforms and fecal coliforms. We applied the water pollution index, which is the average of the ratios between observed parameters and regulated standard values. We found statistically significant inputs for chemical and microbiological contaminants (total and fecal coliforms). The level of chemical contaminants does not compromise the quality of water for human consumption, but the biological contamination does.
