MONITORING OF ARSENIC REMOVAL FROM CONTAMINATED WATER

Abstract

Excessive amounts of arsenic (As) in the groundwater in Bangladesh and neighboring states in India are a major public health problem. About 30% of the private wells in Bangladesh exhibit high concentrations of arsenic. Over half the country, 269 out of 464 administrative units, is affected. Similar problems exist in many other parts of the world, including the Unites States. This paper presents an assessment of the various conventional and novel treatment facilities available for arsenic contamination in the drinking water across the globe. The paper compares various available technologies and lists their comparative merits and demerits and lists specific situations to which they may be applied.
