Delhi’s tap water is most unsafe, Mumbai’s best: BIS | India News


NEW DELHI: Tap water in Mumbai is the safest for drinking while Delhi’s water is the worst among 21 big cities, according to a report based on sample tests done by Bureau of Indian Standards (BIS). Of greater concern is the fact that all the samples of tap water taken from 15 out of 21 cities failed to meet one or more safety parameters during tests carried out in laboratories.
With Chandigarh, Gandhinagar, Patna, Bengaluru, Jammu, Lucknow, Chennai and Dehradun in the list of cities where the tap water quality was found to be below par, the first-of-its-kind report has exposed the failure of water supplying agencies across cities to provide safe drinking water—a basic right for living. The water samples were tested on 28 parameters as prescribed for drinking water standards of BIS notified in 2012.
Releasing the report that ranked the cities based on the quality of potable tap water, Union consumer affairs minister Ram Vilas Paswan said, “We have been working on the task to carry out sample tests to sensitise people and agencies concerned about people’s fundamental right to get clean and safe drinking water. This issue should not be politicised as all of us are concerned about human lives.”
According to the test findings, only one of the samples in Hyderabad and Bhubaneswar failed and the two cities were ranked second in the list followed by Ranchi and Raipur. In the case of Delhi, all the 11 samples picked from different parts of the national capital, including Paswan’s home, his office in Krishi Bhawan and several residential areas, failed to meet the norms on a maximum of 19 parameters.
The report showed that in most cases samples across cities failed on parameters of total dissolve solids (TDS), turbidity, total hardness, total alkalinity, minerals and metals, and presence of of coliform and E Coli, which can cause severe illness.
Citing the alarming test findings, Paswan said there is a need to make the drinking water standard notified by BIS mandatory for all water supplying agencies. He added this becomes all the more important considering it’s not easy to snap water supply and hence efforts have to be made to ensure that the tap water is safe.
Sensing that the report may kick off a fresh political battle, the minister said the objective of the study is not to demotivate anyone rather it is to encourage state governments to ensure quality potable tap water is provided to all. He added that samples across states have failed and in the subsequent phases, BIS will come out with test reports of samples lifted from capital cities of north-eastern states and from smart cities. Later, samples will be picked up from the district headquarters and their test results will be made public.
The test results of these two batches of samples will be announced in mid-January and by August 15, respectively, consumer affairs ministry officials said.
BIS officials said they will soon hold meetings with public health departments, municipal corporations and see how test facilities can be strengthened there, which is key to ensure supply of safe drinking water
