Arsenic is a naturally occurring element found in groundwater and its levels can vary from the water source to another.
Arsenic contamination has been a problem in India, Taiwan, Argentina, Bangladesh, and recently, in parts of California. In Bangladesh, people developed skin lesions and many died of cancer due to arsenic poisoning, while in Taiwan, drinking arsenic-contaminated water resulted in Blackfoot disease, and in Southern California, residents cannot drink the tap water because it’s highly polluted with arsenic.
Scientists claim that even low levels of arsenic can lead to serious health problems, including bladder, lung, and skin cancers, diabetes, cardiovascular disease, and respiratory problems. People should learn a great deal from what Bangladesh had experienced to avoid another large mass poisoning due to contaminated water.
