Abstract
The study area comes in one of the eight districts in West Bengal where groundwater contains arsenic above the prescribed limit by WHO (10 μg/l). Each day, groundwater is being withdrawn by the village people for the fulfillment of their basic needs and for agricultural purposes. With the groundwater along with high concentration of arsenic (As), many other heavy metals are also getting introduced in the environment. In the areas with a long history of use of such groundwater, the agricultural lands have been affected severely. The extent of contamination has increased to a level where the crops grown in those lands are becoming a major source for arsenic and other heavy metals poisoning and subsequently transfer to different trophic levels. Based on this concern a somewhat detailed study was carried out to obtain an idea about the magnitude of water contamination in the area taking the rain-fed pond as control. In case of the pond water, the mean concentration (μg/l) of As (32.63), Fe (57.21), Mn (30.25), Cu (0.82). Whereas in case of shallow groundwater there was more increase in the case of As (76.43), Fe (5493.22), Mn (253.63), and Cu (1.825). Other heavy metals in groundwater were high enough to pose threats but surprisingly the concentration of arsenic even in the pond water was above than the safety standards (32.63?0.88 μg/l) given by WHO (10 ppb) though below than ISI (Indian Standard of Bureau) standard (50 ppb). Thus there is a serious immediate concern for the people and other life forms living in this area regarding the poisoning through crops and drinking water as well.
