  2. For bathing in a river, the desirable level of faecal coliform is 500 MPN/100 ml or lesser, as per the Central Pollution Control Board.
  3. Besides, levels of different pollutants are above permissible limits in ground water samples from different points near the four landfills in Delhi.
  4. Ground water samples from different points near landfills showed that the hardness of water was higher than the desirable limit of 300 mg/l.
  5. The levels of chlorine and calcium were also above the desirable limit in all four samples.
