Analysis of elemental concentration using ICP-AES and pathogen indicator in drinking water of Qasim Abad, District Rawalpindi, Pakistan.

摘要: The present study was conducted to investigate drinking water quality (groundwater) from samples taken Qasim Abad, a locality of approximately 5,000 population, situated between twin cities Rawalpindi and Islamabad in Pakistan. main sources this area are bores which dug upto the depth 250–280 ft almost every house. consists determination physico-chemical properties, trace metals, heavy rare earth elements microbiological water. data showed variation investigated parameters as follows: pH 6.75 8.70, electrical conductivity 540 855 μS/cm, total dissolved solids 325.46 515.23 ppm oxygen 1.50 5.64 mg/L within WHO guidelines for quality. were analysed 30 (aluminium, iron, magnesium, manganese, silicon, zinc, molybdenum, titanium, chromium, nickel, tungsten, silver, arsenic, boron, barium, beryllium, cadmium, cobalt, copper, gallium, mercury, lanthanum, niobium, neodymium, lead, selenium, samarium, tin, vanadium zirconium) by using inductively coupled plasma atomic emission spectroscopy. organic contamination detected terms most probable number (MPN) faecal coliforms. Overall, elemental levels lower than recommended values but three (B-1, B-6, B-7) had higher iron (1.6, 2.206, 0.65 ppm), two B-6) aluminium (0.95, 1.92 ppm), respectively, molybdenum 0.01 ppm only one bore (B-11). coliforms found be prescribed limit except 5 out 11 (B-2, B-3, B-4, B-8, B-11), range 5–35 MPN/100 mL, consequence infiltration contaminated (sewage) through cross connection, leakage points back siphoning.
