Ground report over Delhi's poor water quality

"From just 11 samples, a city's water quality can't be declared as good or bad. We also didn't get any answers when we requested for the details of the places in Delhi from where the samples were collected'', Kejriwal said. Kejriwal said his government is not claiming that all problems in Delhi have been solved. Union Health Minister Harsh Vardhan and Kejriwal also exchanged barbs on Twitter over water quality in Delhi.
