Groundwater is one of the valuable resources in this world. Once the groundwater gets contaminated, remediation is very difficult. So the protection of groundwater against contamination is very important. The quality of groundwater in Noyyal River basin which passes through Tirupur block have been affected very much due to industrial effluents released by the dyeing and bleaching industries in Tirupur. In this context, the present study is an attempt to assess the aquifer vulnerability of Noyyal River basin using Visual Modflow. Groundwater flow for noyyal river basin has been simulated using Visual Modflow- MT3D a versatile groundwater software package. The aquifer characteristics, water level data, pumping wells, observation wells, concentration observation wells, ground surface and bottom elevation, Hydraulic conductivity, porosity, TDS concentration and boundary conditions have been used as model input. The model has been urn through MT3D engine, which is one of the sections in Visual Modflow model. The TDS pollution contamination zones have been find out and classified according to their ranges using Visual Modflow model.
