However, the knowledge of its source, pathways and hydrogeochemistry are still matters of research and study. The aim of present study is the arsenic occurrence in sediments and groundwater in the south eastern Kurdistan, Iran that has caused serious health problems in rural population in the area, especially children, who are running the risk of hazardous effects of arsenic compounds in environment. The goal of this paper is to present objective and systematic data on this problem in south eastern of Kurdistan, Iran.
