Arsenic  values  in  groundwater  above  the  maximum  permissible  limit  of  0.05  mg/l  (Indian standards)  have  been  reported  from  Bhagirathi­Hooghly  flood plain  region  of  West Bengal. The present study area Purbasthali I and II blocks in Burdwan district, West Bengal, evolved due  to  the  flood  plain  forming  processes.  Many  flood  plain  features  are  mapped  using  satellite  image.  Close  links  with  the  geomorphic  features  and  arsenic  pollution  in  the  tube wells  are  observed  here.  It  has  been  studied  that  the  higher  amount  (>0.50mg)  of  arsenic content tube wells are located around the major flood plain features. It is concluded that the processes  of  sedimentation  is  mainly  responsible  for  arsenic  deposition  in  the  aquifers. People living along the major flood plain features must be provided alternative safe drinking water.
