Abstract

HUALLPARA LLIULLY, Lizangela; ORMACHEA MUNOZ, Mauricio  and  GARCIA MORENO, María Eugenia. Assessment of the quality of physicochemical and bacteriological parameters of water springs of la paz city, Bolivia. Rev. Bol. Quim [online]. 2017, vol.34, n.4, pp.104-111. ISSN 0250-5460.

During the emergency caused by the shortage of drinking water for the city of La Paz in November 2016, the local government has used spring water to distribute drinking water to affected areas. The present study has evaluated the physicochemical and bacteriological quality of these water sources and has found that all samples of the studied springs are contaminated by total coliforms with concentrations up to 2400 CFU/ml; it has also been found that 62,5% of the studied springs have high nitrate concentrations up to 105 mg/L. Is then advisable to carry out previously a water treatment for potabilization prior to distribution as drinking water. On the other hand, the hydrochemical characterization has shown that the main water types correspond to Na-Ca-Mg-SO4-HCO3 and Ca-Mg-Na-NO3-SO4-Cl facies; this characteristic of the water has a probable origin in the mineralization and/or dissolution of trona type minerals [Na3(HCO3)(CO3)·2H2O], calcite [CaCO3] and/or thenardite [NaSO4] and anthropogenic contamination with nitrate.
