Impact Of Industrial Effluents On Water Quality In Korba And Environs, Chhattisgarh, India

摘要

The effects of multiple industrial pollution sources on the groundwater system were evaluated in the industrial complex at Korba of Chhattisgarh State of India. The quality of groundwater in the region has been affected negatively due to the discharge of effluents on open land and into ponds, tanks and streams. Water samples from surface water bodies and dug wells were analyzed for their major ion concentrations. The high values of electrical conductivity (EC) and concentrations of Na~+, Ca~(2+), Cl~- and HCO_3~- indicate the impact of industrial effects on water quality. Based on the hydro chemistry, the groundwater is classified into various types such as sodium chloride, sodium-bicarbonate calcium chloride, and magnesium-chloride etc. Its suitability for drinking and irrigation purposes has been assessed. The groundwater quality in and around Korba has become hazardous. Some possible remedial measures are suggested.
