In a span of just 15 days, Delhi was again forced to curtail water production at the Wazirabad and Chandrawal water treatment plants after level of ammonia in raw water went up substantially on Tuesday due to high levels of pollutants. Union minister for environment Jairam Ramesh asked the Central Pollution Control Board to submit a report to him on the issue by Wednesday noon.
"I have asked CPCB to send team for field inspection immediately and report by 12 noon on Wednesday," he told TOI on Tuesday. The minister had written to CMs of Delhi and Haryana last week, asking them to take steps to curtail pollution levels in Yamuna.
According to Delhi Jal Board officials, the level of ammonia in water on Tuesday went up to 1 part per million (PPM) against the permissible 0.6ppm. "At 1pm, we were forced to curtail production by 35% in both plants, which have a combined capacity of 210 million gallons per day. By evening, the situation had improved and levels had come down to 0.7ppm but full production could not be started. We are waiting for ammonium level to decrease further," said a DJB official.
