Physical - Mechanical and Sanitary Indicators in Drinking Waters and in two Mineral Waters of Lushnja District

The study results presented in the paper aimed to deal with drinking water quality of the city and of the district and highlight the characteristics of two mineral water of Lushnja district in the Western Central Albania, according to the “International standards of drinking water” (WHO). The study covering 25 district waterworks, supplying more than 50% of the population. In their waters are determined a large number of indicators, divided into separate groups which are: the odour, taste, colour, temperature, pH, radioactivity and natural radio elements, free carbonic gas, sulphur hydrogen, free chlorine, dissolved oxygen, the total and mineral acidity, total alkalinity, ammonium, biochemical oxygen demand, nitrites, oxidation, nitrates, pesticides, phenols, cyanides, hardness, carbonates, bicarbonates, phosphates, metasilicilic acid, total dissolved solids TDS, anion-cationic composition, fluoride, iodide, iron, zinc, lead, manganese, copper, arsenic and boron. Spectral control have been made for Co, Cd, Hg, Cr, Ni, V, Mo, Se, etc., radiometric and gamma-spectrometric control is made for natural water radio-elements U, Ra, Rn, Th, and bacteriological analyses. Has been observed also the relationship between the chemical composition of groundwater and geological setting of the aquifers.
