Contamination of the environment with arsenic (As) from both anthropogenic and natural sources has occurred in many parts of the world and is recognized as a global problem. Principal anthropogenic sources of As include base metal smelters, gold mines, power plants that burn As rich coals or treated lumber, disposal sites for wastes from As-processing plants, as well as industrial and municipal dump sites. Contaminated land and water generally result from past industrial activities when awareness of the health and environmental effects connected with the production, use, and disposal of hazardous substances were less well recognized than today. Due to this fact in the case of Bahir dar city there was an industrial zones based on this there are many factories those released wastes that contains toxic metals like Arsenic. Those factories released wastes without any treatment that ends with adverse health problems. The toxicity and distribution of arsenic in the environment make it evoking public concern. Therefore swift removal of metals such as arsenic from contaminated sites is one of importance. Several bioremediation technologies are existing for the remediation of As from contaminated soil and water, however, among bioremediation it is better to apply Phytoremidation due to its comparative advantage. As a result in order to reduce the already mentioned chaos so it is possible to alleviate this problem with new technology of Phytoremediation of soil contaminated with Arsenic by using Phragmiteskarka grass.
