In North Eastern States, though surface water is supplied to the people in hilly areas but in plains groundwater is extensively used for public supply. In the State of Assam where major sources of public water supply are groundwater, people in several districts are facing problem due to contamination of groundwater with excess iron, arsenic and fluoride. Tripura State is also mostly groundwater dependent and in this State 53.11% habitations are facing problem due to presence of iron beyond permissible limit. In addition, presence of arsenic beyond 10 ppb (acceptable limit) could be found in Tripura. In the States of Arunachal Pradesh, Meghalaya and Nagaland where groundwater is supplied, presence of iron beyond permissible limit has been reported.
