At the present time people are aware of about the drinking water contaminants and health risk. Since 1970's, when sampling for contaminants increased, hundreds of manufactured chemicals have been identified in various ground water and other drinking water supplies. Source water contaminants of concern include arsenic, asbestos, radon, agricultural chemicals and hazardous water. Of these, the strongest evidence for cancer risk involves arsenic, which is linked to cancer of the liver, lung, bladder and kidneys. A survey was conducted during 2011to2014 in some selected areas of Nalbari and Kamrup district of Assam to know the occurrence of cancer and different types of diets consumed with the help of a prepared questionnaire. Water samples were collected in different regions accordingly during pre and post monsoon period. Spectophotometric method was used to find out the arsenic in drinking water sources. Our study confirmed a higher level of arsenic content in drinking water sources in all the selected spots.Prevelrnce of cancer in the study area was also reported high.
