Abstract:
Cauvery River, one of the major rivers in the peninsular regions, is the major source of water for domestic, agricultural and industrial uses in major parts of Karnataka and Tamil Nadu. Detailed investigation of the interaction between surface water and groundwater is important for water resources management as well as the determination of migration pathways for contaminants. Geochemical processes that take place in the aquifer play a major role in spatial and temporal variations of groundwater quality. The physical parameters like EC, pH, ORP, and HDO of water samples show similar trends in the declination in surface water as well as groundwater. The trace metal like (Zn, Pb, Cu) concentration in the surface water and the groundwater also the concentration of the major ions showing an increasing trend toward the coastal region. The electrical conductivity of the surface water varies from 546.2 to 15360 μS/cm and the electrical conductivity of the groundwater is varying from 502.2 μS/cm to 1976.0. The maximum concentration of Na+ is 3710 mg/L to 46 mg/L in a surface water sample and 461.50 mg/L to 44.5 mg/L in a groundwater sample. The maximum concentration of K+ is 200 mg/L to 5.3 mg/L in the surface water and 50.64 mg/L to 3.6 mg/L in the groundwater. The results presented here demonstrated the surface water and groundwater interaction using the proxies of major and minor ions.
