Study of Correlation of Drinking Water in Indore City (M.P.)

In the present study, various drinking water samples have been studied in Southern Indore city of (M. P. ). Water samples have collected from various water sources namely tap water, boring water, well and hand pump. Water samples were analyzed for various water quality parameters like pH, electrical conductance, total dissolved solids, total alkalinity, total hardness, chloride, sulphate, nitrate, fluoride, sodium, potassium, mercury, iron, copper, zinc, lead and cadmium. In the present study 23.33 %, 25 %, 28.33 % samples of total hardness were cross the standard permissible limits as (300mg/l) during rainy, winter and summer seasons. Only 81.25 %, 84.37 % and 84.37 % of drinking water samples for TDS crossed the permissible limit as 500 mg/l (BIS, 1998) in Rainy, winter and summer seasons respectively. In the present study the values of fluoride, nitrate and sulphate found were under the permissible limit in all the drinking water samples. None of the water samples crossed the permissible limit for heavy metals namely Copper, Cadmium, Mercury and Lead except Zinc. Pearson& #039, s correlation coefficient (r) values among various water quality parameters of all the samples were computed.
