Pesticides play important roles in agriculture, aquaculture, food processing and storage by preventing disease and protecting crops, however widespread use has led to pesticide pollution in surface water at levels hazardous to health. Pesticides are often recalcitrant to conventional biological wastewater treatment.                                                                                                                                                                    Pesticide residues are frequently found in surface water at levels hazardous to health even in low concentrations. Overflow from pesticide-treated areas can contaminate surface waters like streams, ponds, lakes as well as groundwater wells with pesticide residues. These residues in surface water may harm aquatic plants and animals and pollute groundwater supplies. Contaminated water can also impact livestock and crops downstream.                                                                                                                                                                    These recalcitrant and toxic pesticides persist through conventional treatment methods such as biological treatments,incineration and flocculation/coagulation etc.
