Guwahati's Drinking Water Fails in Purity Test
GUWAHATI: Beware! The water you are drinking in Guwahati is not safe to drink. A test carried out by Bureau of Indian Standards (BIS) taking samples from 10 places failed miserably in the test, hence opening up a can of worms about basic civic amenities provided by the sate government.
According to a BIS study released on November 16, Guwahati failed in all ten parameters in the quality of water among capital cities in states where samples of tap water (drinking) were tested.
According to the study, 10 samples were collected from Guwahati in which, it failed in all the BIS tests. Further, it failed in 5 individual parameters in the samples which were collected, thereby reaffirming that Guwahati has the poorest water quality.
Among other cities, Mumbai ranks the highest in the quality of water among capital cities in states where samples of tap water were tested. Second in the list was Hyderabad, where only one sample failed.
Previously, large amounts of arsenic has been found in water samples in Guwahati making it extremely unsafe for consumption
Union Minister Ram Vilas Paswan said that in the third phase, samples from capital cities of Northeastern States and Smart Cities have been identified by Ministry of Housing and Urban Affairs and are being tested.
The result of these is expected by January 15th, 2020.
