Evaluation of Drinking water quality parameters in the areas of East - Lahore Pakistan : A case study

Water quality supplies for residents of east lahore has been investigated and evaluated. for this purpose six sampling locations were selected which includes four sampling points from urban areas and two from the rural areas. samples from the urban areas were collected from tube well which is connected to filter plant and also samples have been collected from three house connections of that area (tap water). for the assessment of water quality of the rural areas, samples were taken from three house connections (tube wells) of each sampling point. physical characterizations (turbidity and ph), chemical characterizations (hardness, total dissolved solids, sulfates, chlorides) and biological parameters (total coliform and fecal coliform) were tested and compared with national standards for drinking water quality (nsdwq). the results demonstrated that physical parameters provide almost satisfactory status. however, minor issue of hardness and turbidity were found. at consumer end, of the samples of location t1hc and t4hc were found, bacteriologically contaminated; hence compulsory chlorination is recommended. currently in these areas, people are using bores having maximum depth of 150 feetwhich causes physiochemical contamination.
