Preliminary hydro chemical evaluation of water reservoirs close to mining activities in the Hampaturi micro-basin in La Paz, Bolivia. The preliminary hydrochemical evaluation of the water reservoirs for human consumption close to mining activities in the Hampaturi micro-basin in La Paz, Bolivia, administered by the Public Social Water and Sanitation Company (EPSAS in Spanish) was carried out. The results of the physicochemical field and laboratory analyses show two kinds of water. Meltwater from elevated Andean glaciers with a neutral to slightly alkaline pH, low electrical conductivity (EC) values and low total dissolved solids (STD) values with high dissolved oxygen saturation (DO) values. and low concentrations of Na+, K+, Ca2+, Mg2+, Cl-, F-, NO3 - y SO4 2-, classifying them according to the WHO as demineralized waters. The second class of water from sampling points outside the dam system and corresponding to the Hampaturi River, shows evidence of mining tributaries that provide high concentrations of the aforementioned analytical parameters. Therefore, according to the Regulation on Water Contamination of Law No. 1333, they are classified as unfit for human consumption.
