Dehradun based NGO, Society of Pollution and Environmental Conservation Scientists (SPECS), conducted a survey by testing water samples of 125 localities across Dehradun district between June 10, 2020 to July 10, 2020.
The survey revealed a shocking result that the tap water supplied in 65% of the 125 surveyed localities across the district has the presence of fecal coliform which is a major contributor in causing stomach related diseases. The study also revealed the high amount of absorbed chlorine in tap water which was found to be below the prescribed level in several localities.
As per the Bureau of Indian Standards (BIS), the acceptable limit of Chlorides is 250 mg/l and the Permissible limit is 1000 mg/l and the limit of Coliform Bacteria is Nil/100ml. In context to these parameters, the contamination of tap water in the Dehradun district is alarming, stated the study. The presence of a high amount of Chlorine can lead to high blood pressure, skin problems and other health-related disorders.

Dr Brij Mohan Sharma from SPECS said to media, “the presence of fecal coliform indicates that people are consuming water which has the presence of waste from underground sewage. If residents continue to consume such poor-quality water for a long time, it can result in a massive deterioration of health for them”.
The study also indicated that the tap water supplied in certain areas including Rajpur, Johri Village, Doon Vihar, Malsi, Vijaypur Road, DL road and Niranjanpur have a high presence of hard water contents.
Contaminated water samples often contain harmful chemicals like Arsenic, Mercury, Cadmium and Lead.
