Analytical Study of Water Safety Parameters in Ground Water Samples of Uttarakhand in India
Subscribe/Renew Journal
Background: There is plenty of water available in hills, the main problem of the locality is the drinking water. These water resources are not exploited for drinking and irrigation purposes. Also, certain health problems are associated with people living in hills that are because of the presence of excess of heavy metals and other impurities.
Aims and Objectives: The present study was conducted to analyze the various parameters of ground water in uttarakhand, India and to check its fitness for drinking. It will also clarify the health hazards imposed on the population of this state.
Design & Setting: The present study was conducted in five regions of Uttarakhand, India (Haridwar, Vikasnagar, Mussoorie, Dehradun & Dakpathar) during 2006-2007. Ten samples of ground water were collected from each of the five regions during the pre-monsoon (Jan-Feb 2007) and post-monsoon (Sept-Oct 2006) seasons.
Materials & Method: The pH was estimated by pH meter and the alkalinity was determined by titration methods. The total suspended solid was calculated by the following formula: Total suspended solid (mg) / ltr = (A-B) x 1000 / sample vol. In litres. Where, A= weight of filter + dried residue, B=weight of filter paper. Total hardness was calculated by adding calcium and magnesium hardness derived by EDTA titration method. The chloride was estimated by silver nitrate titration method and sulphates were estimated by titration method. The different heavy metals (Mn, Al, Ba, Cd, Cr, Co, Cu, Fe and Pb) were determined in the ground water samples by ICP mass spectroscopy.
Results: The concentrations of heavy metals, pH, alkalinity, sulphate, chloride, TDS & Total Hardness (TH) were compared with the standards set by BIS for Drinking water (IS 10500:1991). The results show that water quality of all the five regions studied showed no remarkable variation from the BIS recommended value of pH (6.5-8.5). The alkalinity was above the BIS desirable level of 200mg/l in all the samples, but was less than the maximum permissible limit. The Drinking water of all the regions contains higher amounts of TDS than the desirable limits. The maximum TDS was detected in Haridwar (682.5 mg/L) and dehradun (610 mg/L) state. The ground water of mussoorie region shows total hardness to be above the BIS desirable level of 300mg/l. The chloride content was above the BIS desirable level of 250mg/l in dehradun only. The sulphate content was highest in haridwar (197.5mg/l) and dehradun (170mg/l) but it was below the desirable limit of 200mg/l. The cadmium (Cd), chromium (Cr), and lead (Pb) content of all the five regions of Uttarakhand showed higher the BIS permissible limits of 0.01, 0.05 and 0.05 mg/l respectively. The content of manganese (Mn), barium (Ba), Copper (Cu), cobalt (Co), iron (Fe) are within the permissible limit of BIS standards for drinking water.
