Abstract:
Present study was conducted to analyze the physicochemical and heavy metals concentration in different industrial effluents to check the treatment plant efficiency of selected industries. Twenty eight waste water samples, before and after treatment was collected and analyzed by using standard operating procedures. In order to determine the efficiency of industrial wastewater treatment plant and their effect on groundwater the results obtained were compared with PAK-EPA standards. Some parameters including pH, Total suspended solids, Fluoride, Iron, Zinc, Nickel, found within permissible limit whereas rest of parameters including TDS, EC, Chloride, Cadmium, Lead, Cobalt, were above the permissible limit as compared with Pak-EPA limits. Wastewater treatment plants were efficient in reducing the amount of TSS, Fe. In order to analyze the impacts of this wastewater on nearby groundwater. Sixteen groundwater samples were collected and analyzed for the same parameters. In groundwater pH, Electrical conductivity, Total dissolve solids, Chloride, Iron, Cobalt were found within the allowable limit whereas Lead, Nickel, Zinc were found above limit in few sampling locations. Total suspended solids, Fluoride, Cadmium, were above the limit. Two surface water samples were also collected from Nallah Lai. It is observed that groundwater samples, having less depth and near to industries, Nallah, were found highly contaminated. Therefore from the present study, it is concluded that industrial effluent should be treated before releasing into the surrounding environment and PAK-EPA should have regular monitoring to check and balance in the industrial sector.
