Ram Prajapati  | Ram Singh Muzalda
Abstract: Drinking water of various samples namely tap water, boring water and hand pumps water were taken from different locations of North Indore city. Total 64 samples were collected in different seasons in 2010-2011. Water samples were analyzed for various water quality parameters like pH, TDS, EC, Total Hardness, calcium, magnesium, Total Alkalinity, Bicarbonate, Carbonate, Nitrates, Chlorides, Fluorides, Sulphates, Sodium, Potassium, Iron, Copper, Zinc, Lead, Cadmium and Mercury. Much higher values of TDS Varied from 296 mg/l to 1702 mg/l during summer season, it crossed the standard permissible limit as 500 mg/l. In the summer season the range of total hardness from 188 mg/l to 706 mg/l that was much higher than the standard permissible limit (300 mg/L) (BIS, 1998). In the present study only 1.56%, of drinking water samples for copper crossed the permissible limit as 0.05 mg/l. (BIS, 1998) in Rainy season and 20.31%, 15.62% and 18.75% of drinking water samples for Mercury crossed the permissible limit as 0.001 mg/l (WHO, 2004) in Rainy, winter and summer seasons respectively. In the present study none of water samples crossed the standard permissible limit for Fluoride, Nitrates, Sulphates, Sodium and heavy metals namely Iron, Zinc, Lead and Cadmium. Pearson's correlation coefficient (r) values among various water quality parameters of all the samples were computed.
