Comparative Study over the years of Ground Water Quality in Bhubaneswar City
Pages : 1720-1729
Most of the water requirement for Bhubaneswar city is met from ground water supplies. So it is essential to know the quality of ground water for suitability in drinking purposes. In view of that a study was therefore undertaken to see the quality of ground water. For that nine sampling points were taken for water sampling in three different seasons ( winter, summer, rainy) for two consecutive years of 2009 and 2010. The results obtained has been compared with the standards. The yearly average of all the parameters were calculated and compared graphically. From the results correlation co-efficient among different parameters has been calculated. Most of the parameters are found below permissible limit in most of the locations, except high quality of iron was found in most of the samples. All the samples found to have highly turbid. The ground water of the study area was with respect to TC,FC are below the WHO limit. From correlation coefficient it was found that EC, TH, Cl-, TDS have strong correlation with each other. Iron was found to be negatively correlated with F-.
