Sir: Water pollution is creating major threats to public health. Pakistan is included among the countries most affected by water pollution. This situation is awful and many people do not have access to potable water. Out of 122 countries it is ranked at 80 in terms of the availability of drinkable water. The people are compelled to buy toxic water from the tanker mafia, which is causing diarrhea, typhoid, intestinal worms and hepatitis. It is also estimated that more than 250,000 children die due to water borne diseases each year. As many as 3.5 million children are at high risk of these diseases and can die at any time. This is because the water we use is full of bacteria. I request the concerned authorities to provide citizens with access to drinkable water.
