Islamabad — A new study has revealed that 50 million People in Pakistan’s Indus Valley could be at risk of drinking arsenic contaminated groundwater, far more than previously thought.
The study, published in the journal of Science Advances found arsenic levels in groundwater in parts of Pakistan’s Indus Valley to be more than 20 times the safe level of 10 micrograms per liter of water recommended by the World Health Organization (WHO).
Arsenic is a solid substance (metalloid) naturally existing in the Earth’s crust and in crushed rock. Humans come into contact with it because it leaches into groundwater from rocks and sediments.
Lead author Dr Joel Podgorski, environmental scientist at the Swiss Federal Institute of Aquatic Science and Technology (Eawag), said that the findings of the study indicate an alarmingly high number, which demonstrates the urgent need to test all drinking water in the Indus Plain.
