Groundwater Organic Contamination with Limited Efficiency of Pump and Treat Remediation


The groundwater plays crucial role as a decentralized source of drinking water for millions cannot be overstated. Groundwater is generally less susceptible to contamination in comparison of surface water bodies. Also, the natural defect in rainwater gets removed while infiltrating through different soil levels. But, In India, the groundwater is used for irrigation and industrial work, a variety of land and water based activities are causing pollution of this resource. Its over-exploitation is causing aquifer contamination, while insufficient knowledge of groundwater flow dynamic and geo-hydro chemical process has led to its mineralization. The pump and treat remediation is used generally in case of contamination by hazardous wastes. This technique filters groundwater as a hydro chemical process through flow in columns with pores to filter molecules. We observed role of Absorption/desorption and dissolution of non-aqueous phase liquids on the effectiveness. The results showed that the remediation of groundwater depends directly on the physical/chemical properties of the contaminants and the hydrogeology of the site. The remediation of groundwater contaminated by hazardous waste using P and T technique is limited and expensive for mass pollution.
