Chemical analysis of ground water from various parts of Thiruvarur and Nagapattinam district, Tamilnadu, India

摘要

The present study consisted of the estimation of some heavy metals and quality of groundwater from Thiruvarur and Nagapattinam district, Tamilnadu(India).The water sample were collected from various parts of Thiruvarur and Nagapattinam region during Jun-2013. The physicochemical parameters such as Ca2+, Mg2+,Cl- were analyzed by titration method. SO4 2-, Fe3+, Al3+, NO3 -, NO2 -, Cu2+,Mn2+, were estimated by spectrophotometric method. Colour of the water sample determined by platinum-cobalt method. TDS of the water sample determined by gravimetrically,PH was estimated by PH meter. Turbidity was estimated by nephelometric method. Data showed the variation of the investigated physicochemical parameters in sample as follows, TDS of groundwater from Thiruvarur and Nagapattinam region rang between 320mg/l – 1830mg/l and 286mg/l – 1110mg/l respectively. The Total alkalinity of ground water from Thiruvarur and Nagapattinam region range between 108mg/l – 486mg/l and 166mg/l – 368mg/l respectively. The concentration of most of the chemical parameters in the drinking water sample from Thiruvarur and Nagapattinam region excess range the permissible limits of the BIS drinking water quality guideline, most of the region water quality was found unsatisfactory for drinking purpose.
