Dilip Sutradhar and Satyajeet Kumar

Water is the most essential commodity for the entire living system on the earth. Water pollutants are increasingly contaminating ground water. To monitor water quality, 20 water samples were collected from various locations of Hailakandi town and were analysed by standard methods. The 20 sources include 8 Tube wells, 4 supply samples and 5 ponds and 3 ring wells. The study has been carried out from December 2011 to August 2012. The study report shows that 4 tube well, 2 pond water and 1 ring well samples contain arsenic above permissible limit and are unsafe for drinking purposes. Again 2 tube well, 1 PHE and 2 pond water sources contained fluoride above permissible limit and cannot be recommended for drinking and other domestic purposes.
