The residents in the holy city were put to serious health risk due to polluted drinking water sources. At least four people have lost their lives due to jaundice here and over 400 cases have been reported in last three months. Of late, the Public Health Department (PHD) conducted a random test of the city potable water sources and found14, 000 shallow tube wells and hand pumps located in close proximity to drains and sewers and producing contaminated water unfit for human consumption. Underground water table in the city is found to contain alarming level of Coliform bacteria harmful to human health. DM Arabind Agarwal has directed the PHD and the civic body to seal these water sources. The PHD was asked to shift the bore wells and tube wells to safer places.
