Groundwater Quality Study Of Amaravathy River Basin Of Karur District, Tamil Nadu

摘要

Amaravathy river is the main water source providing water for drinking, agriculture and industrial activities of Karur district. In the last two decades the extensive growth of bleaching and dyeing industrial activates in Karur has adversely affected the river water quality as well as the groundwater quality of the river basin. PWD and CGWB regularly monitor the quality of groundwater in the district. TNPCB monitors the quality of river water and the effluent discharge from the industries. From the date base, it is observed that the total dissolved solids, chlorides in the groundwater of Amaravathy river basin is above the desirable limit for drinking water. The quality of treated effluent discharged from textile bleaching and dyeing units into Amaravathy river reveals that total dissolved solids, chlorides, BOD and COD exceeded the inland surface water discharge standards. In order to over come the existing river and groundwater pollution, the bleaching and dyeing units should implement ZLD plant by providing RO plant with complete reject management system to recycle the entire effluent. Karur domestic sewage should be completely collected, treated and used for farming. Municipal solid waste and hazardous waste from the industries should be properly collected and disposed off.
