In Bengal Delta Plain (BDP), shallow aquifer (<50 m) is often contaminated with Arsenic (As). The phenomenon is wide spread in nature thought the BDP notable in Nadia district of west Bengal. The present study highlights a primary screening of As, Fe, MPN and FC in monitored shallow wells. The study designed for two different sites (site-A, High As and site-B Low As area). The water quality monitoring results suggest that high As concentration (Range- 103-171 μgL-1) has been noticed in site A when compared with site B (range-53-99 μgL-1). In sites A, the Fe concentration is high and low in site B. The correlation study (r2 ) between arsenic and iron are also determined. The value of r2 is 0.94 for site A and 0.73 for site B. The water quali...
