Sir: It is very unfortunate that Karachi, which is Pakistan’s biggest metropolis, does not have water which is fit to drink. The situation is so bad that even the uneducated and the poor know that drinking this water can be lethal but they drink it anyway because they have no other choice. I request that the government take action in this regard as soon as they can. GULNAZ GANGA Turbat Published in Daily Times, December 8th 2017.
