Impact of industrial effluents on groundwater quality.
A survey was conducted to assess the long-term effect of industrial effluents on groundwater quality for irrigation. Kattedan industrial area (India) was selected and five contaminated locations were identified. From each location, water which is being used to irrigate the crops, was collected during the months of October 2005 and February 2006. The results indicated that the concentrations of all parameters were higher in groundwater samples of Kattedan industrial area and they were found more in water samples collected during the month of February 2006 than those collected during October 2005. Among different parameters studied in water samples, Ni, Cd, Zn, Ca, Mg, TS, Na and SO4(2-) were found within the permissible limits for drinking. The results of the water samples indicated that the water of Kattedan industrial area is not suitable for drinking and irrigation purpose.
