Physico-Chemical Characteristics of Ground Water in and around the Gandhamardan Iron Ore Mining area, Keonjhar District, Odisha, India

摘要

Mining and associated activities have quantitative and qualitative impacts on the water regime in and around the mines. Due to presence of iron ore belt water pollution attracts the attention of all. In the present study the ground waters around the Gandhamardan mining areas have been tested, where the iron ore opencast mines are present. The water quality parameters, viz. pH, Seasonal variation of different parameters have been compared with the standard. From the results mean, standard deviation, correlation coefficient and principal component analysis among parameters have been studied. The results show that ground water collected from different six locations with minimum variation in pH value ranges from 5.4 to 6.6 suggest acidic nature. Other parameters were more or less within the permissible limits of WHO.
