Abstract
Arsenic contamination is turning out to be a major problem these days with its increasing area coverage and the number of people affected directly or indirectly. Now, the level of the contaminant has spread over the soil and sediments from groundwater and other natural sources. Arsenic poisoning in groundwater events is familiar to the world, but the consequences of soil contamination are still unrevealed to the community. Long-term use of arsenic contaminated groundwater to irrigate crops, especially paddy (Oryza sativa L.) has resulted in elevated soil arsenic levels. Now the time is right to take into account the soil contamination of Arsenic and to devise cost effective remedial measures to correct this problem. This article deals with some of the remediation technologies included within broad category of physical, chemical and a few biological methods.
