Arsenic and Water

There are arsenic contaminations in drinking water around the world. Arsenic occurrences are found naturally in sediments or they originate from industrial pollution, agriculture and mining.

More than 130 million people around the world consume arsenic contaminated water, which largely exceeds the World Health Organization's (WHO) threshold of 10 μg/L (UNICEF 2008). Estimates show that up to 77 million people in Bangladesh alone are directly affected by a fluctuating release of arsenic into the groundwater (WHO 2013).

Skin lesions, an increased risk of cancer and even death are the consequences of drinking water containing arsenic on a regular basis.
