Rajasthan Chief Minister Vasundhra Raje today sent a letter to Punjab Chief Minister Parkash Singh Badal over the unchecked flow of polluted water through the canal system originating from Ferozepur. Well-placed sources said Vasundhra has said that industrial units in Punjab discharge hazardous waste into the Sutlej and and its tributaries. She has urged Badal to initiate strong measures against the industry and civic bodies as “untreated water has polluted river waters beyond proportions.” Vasundhra expressed concern over the poor quality of water being released into Indira Gandhi feeder through the Harike barrage as millions of people in eight districts used this water for drinking. The polluted water had resulted in a spurt of water-borne diseases in the area, Vasundhra has said. The letter says the Punjab Government had ignored letters by Rajasthan on the issue.
