Answer: In chemistry, arsenic is referred to as a violently poisonous white compound of the bristle element. Arsenic in groundwater is present in excess of the safe limit set for Bangladesh. It is now established that arsenic can cause a serious health hazard. The rural people of Bangladesh are mostly dependent on hand tube-wells for drinking water. The groundwater was, in the past, considered to be a source of safe drinking water. Unfortunately, it is now polluted by arsenic. Until the 1970s in areas where the drinking water supply contains unsafe levels of arsenic, the immediate concern is finding a safe source of drinking water. There are two main options: finding a new safe source and removing arsenic from the contaminated source. In either case, the drinking water supplied must be free from harmful levels of arsenic, but also from bacteriological contamination, and other chemical contaminants. So, all of us should come forward to solve the problem of arsenic.
