Delhi: The politics over the quality of water in Delhi became intense when on Monday chief minister Arvind Kejriwal strongly rejected the Bureau of Indian Standardisation (BIS) report that had stated the tap water in the national capital has failed quality tests and has been found unsafe to consume. He said no conclusions about the city’s supply should be drawn on the basis of 11 samples.

However, after Kejriwal raised questions over a report, Union Minister Ram Vilas Paswan constituted a team of two senior BIS officials and asked him to nominate competent officers on his behalf to re-examine the water quality.

"I have informed Chief Minister of Delhi Arvind Kejriwal by writing a letter that I have formed a team of two senior BIS officials to re-examine the water quality of Delhi and Kejriwal can also nominate competent officers on his behalf so that samples can be tested," Paswan tweeted.

Earlier in the day, Kejriwal had said that the city's tap water quality cannot be judged based on an analysis of just 11 samples. "Any city's water quality cannot be judged on the basis of just 11 samples. Moreover, Union Minister Ram Vilas Paswan is not disclosing where the samples were taken from. I will take five samples from each ward of Delhi, get it checked and then put the data in public," he said.

Earlier, union health minister Harsh Vardhan said that in the name of free water, Kejriwal was making Delhi residents drink poison. Calling the water quality report fake and influenced by politics, Kejriwal advised Vardhan not to become a part of the dirty politics.

On November 16, Paswan said that tap water in Delhi and several other cities did not comply with the requirements according to a study conducted by the Bureau of Indian Standards (BIS). "Mumbai tops ranking released by the Bureau of Indian Standards (BIS) for quality of tap water. Delhi is at the bottom, with 11 out of 11 samples failing on 19 parameters," he had said.
