摘要：Groundwater always contains some amount of chemical substances, and their concentration is afunction of the initial composition, rainfall, land use, type of surrounding rocks, and the recharge processes. VasitaNadhi is one of the important tributaries of Vellar River which originates in the Kalvaraayan Hills, Tamil Nadu, India.The basin lies between 11°22’0’’N and 11°53'0’’N latitudes and 78°29’0’’ E and 79°0'0’’ E longitudes. The aerial extentof the basin is about 1478 km2. As groundwater is the major source for drinking and irrigation in the Vasita NadhiRiver Basin, and the water available in the river and surface water bodies are not sufficient to meet out the demand fordrinking and irrigation, it is essential for an integrated study of groundwater flow and quality. The effluents of Sago andhybrid-seed industries are directly disposed on land and surface water bodies without proper treatment. Thus, a detailedstudy has been carried out in Vasita Nadhi River Basin to understand the quality of surface and subsurfacewater.Various thematic maps pertaining to the water quality study were prepared using Geographical InformationSystem. Thirty three groundwater samples and twenty five surface water samples were tested during March -2017 forpH, temperature, electrical conductivity, total dissolved solids, salinity and dissolved oxygen using portable waterquality kit. Tested water quality parameters were compared with the BIS and WHO standards to understand thesuitability of water for drinking and irrigation. Spatial variation of groundwater quality parameters were plotted usingGIS. Groundwater flow patterns were also plotted using GIS from the measured groundwater head with respect to GPSdatum. It is observed from the results that groundwater is highly affected in 1/3 of the basin area leading unsuitabilityof water for drinking and irrigation. Most of the surface water bodies and river channels were also affected by theeffluent of Sago industries.
