Study of physicochemical conditions of discarded diesel contaminated Locoshed pond near Burdwan locomotives of Burdwan, West Bengal

Studies on the physicochemical characteristics of the diesel fed loco-shed pond adjacent to Barddhaman (Burdwan) Railway Station of the Burdwan town were carried out in different seasons, i.e., winter, pre-summer, and summer during the year of 2009 - 2010. Sampling was done from the pre-determined four points (P₁N, P₂N, P₃S and P₄S) to evaluate the impact of oil pollution on the physicochemical status of the water body. Various physicochemical parameters were analyzed, including water temperature, water pH, water conductivity, dissolved oxygen, total alkalinity, chloride, total hardness, calcium and magnesium hardness, BOD, COD, total iron, reactive silica, ammonia, nitrogen, sodium, potassium, nitratenitrogen, sulfate, TDS, TSS and, oil and grease content of the water. Oil and grease content is very high in the summer season. The main inlet point of discarded diesel in this pond is P₃S, where oil concentration is very high up to 6000 mg.L⁻¹.
