Assessment of Impact of Human Interferences including Mining Activities on Water Quality of Banas River, Rajsamand City, India

An attempt has been made in the present study to assess various physico-chemical parameters and heavy metal analysis of water quality in Banas river, Rajsamand city, India. To maintain a balance in an aquatic ecosystem, the inter-relationship between varieties of factors is essential to maintain the water potability at a high level. It is confirmed that mining has a substantial influence. Present study examined pre- and post-monsoon physico-chemical variables, heavy metal analysis and computed water quality index, eutrophication index, organic pollution index and heavy metal pollution index. The pH, EC, COD, total hardness, zinc, silver and iron were within the acceptable limit, whereas the TDS, phosphate, dissolved oxygen, BOD and lead were found beyond the permissible limit. Therefore, the present study provides the essential information about deteriorating river water quality. Most crucially, a number of external factors like mining, soil erosion, religious activities, daily human needs activities, etc. are responsible for the degradation of water quality of nearby Banas river.
