Emancipation of Effluent from Fertilizers and Chemical Pesticides Causing Water Contamination at Rishipur Village, West Bengal, India

The numerous uses of chemical pesticides have got amplified to a great extent with the instigation of the green revolution which resulting in enormous increase in the crop production which eventually builds the economy of an area. This progression of contemporary cultivation has led to filthy stipulation of nearby water bodies. The present paper deals with the water contamination occurring due to frequent application of inorganic fertilizers, agrochemicals and chemical pesticides at agriculture based Rishipur village of West Bengal, India. The filthy condition of the water was observed more deteriorated after a definite time of applying chemical pesticides in the agricultural field. The consequence of pesticides effluence in water has been discussed in this paper. For comparative study, the physico-chemical characteristics of water of nearby wetland of the agricultural field and water drawn from hand pump, various physico-chemical parameters viz. pH, conductivity, TDS, concentration of Cl-, SO4–2, CO3–2, HCO3-, Ca+2, Mg+2, DO, BOD, COD have been studied in the month of November, 2018. The present study signifies that the contemporary agricultural practice can cause severe environmental destruction in the long term.
