New Delhi, 11 July
The Opposition BJP has demanded the resignation of the chief minister, Mrs Sheila Dikshit, for failing to provide safe drinking water to the residents of capital.
 "A 36-year-old man was killed and about a dozen people reportedly took ill after drinking contaminated water from bore-wells in a jhuggi-jhonpri cluster near the BSF camp at Rajokri in south-west Delhi. The incident comes close on the heels of another similar case reported from NCERT Colony in South Delhi last month, in which two persons died and scores were hospitalised due to gastrointestinal problems," said the Delhi BJP general secretary, Mrs Shikha Rai, and South Delhi Mayor, Ms Sarita Chaudhary, after visiting the Rajokri camp to take stock of the situation.
Mrs Rai said in a purity test conducted by the MCD in 2012, it was found that the drinking water that most Delhi’ites are getting at home is contaminated with sewage water and could be harmful to health. A shocking 81 out of 116 samples of such water ~ almost 70 per cent of water supplied across the Capital by the DJB ~ failed the test conducted by the MCD. The MCD study concluded that the tap water flowing through DJB pipelines could itself be the cause of various water-borne diseases. The water samples were collected by the civic authority’s public health department laboratory in May 2012.
The bacteriological report submitted recently contains some alarming details. In up market south Delhi, impurities were detected in as many as 17 out of 28 water samples. The posh colonies getting a deadly cocktail in their taps included Green Park, Hauz Khas, South Extension, Safdarjung Enclave and Greater Kailash. Seven out of 10 of the samples in west Delhi’s Karol Bagh zone were found to be polluted, while 28 out of 32 samples were not up to the mark in Paharganj zone which covers the Walled City. 
The Civil Lines area of north Delhi, too, did not fare much better as 15 out of 26 samples failed to meet purity norms. Delhi University and the region around it are located in this zone. But the residents of Narela in northwest Delhi appeared to be the worst-off because the water quality of all 10 samples tested there was found to be poor. In the central zone, which comprises areas such as Lajpat Nagar, New Friends Colony and Maharani Bagh, two out of six samples couldn’t pass muster.
