Quality of drinking water and associated health risks
New Delhi, 11 May, 2016: A new NIH study links arsenic in drinking water from private wells to bladder cancer.
The quality of water has an important impact on public health. Presence of contaminants, either microbial or chemical, puts health of people at risk. Water-borne diseases such as diarrhea, cholera, dysentery, typhoid, worm infestations are well-recognized and constitute a major cause of mortality and morbidity worldwide.
It’s not only the surface water in rivers and lakes that is susceptible to contamination, groundwater or water in wells too is susceptible to contamination through poor management of industrial or agricultural waste. Groundwater may also be contaminated by naturally occurring chemicals. Drinking water requires appropriate treatment to remove the hazardous contaminants before it is fit for drinking. Water sources that are unprotected are at a great risk of contamination and become unfit for drinking.
