Analysis of Trace Metals in Underground Drinking Water of Bareilly

Quality of drinking water of the Bareilly has been studied and the results are presented in this paper. A total of 45 drinking water samples were collected from 15 different locations of the Bareilly and brought to the laboratory for analysis. Samples were analyzed for physico-chemical parameters such as pH, electrical conductivity (EC), total dissolved solids (TDS), temperature and seven trace metals (Zn, Cu, Mo, As, Ca K, Mg) using standard procedures. The results were compared with other national (BIS) and international (WHO) standards. pH of the tested samples was in the range of 7.06 to 8.46 while the temperature ranged between 31.2 to 34.6°C. EC of water samples was recorded in the range of 375 to 1994 μs cm^-1 whereas TDS in the range of 263 to 897 ppm. In all water samples, pH ranged in the permissible limit whereas EC and TDS of some of the samples were above the permissible limit. Concentration of metals namely Zn, Cu, Mo, As, Ca, K and Mg were found in the range of 0.16-2.29, 1.11 to 1.96, 0.016-0.093, 0.001- 0.005, 30.44-99.09, 2.16-5.81 and 1.93-12.53 mg/l respectively. All the metals were found in limit except copper, molybdenum and calcium which exceeded the limits set by WHO (2004) and (BIS 2003) at some studied sites.
