Abstract: 

This study deals with the variations of Cd, As, Pb and NO3- levels in the groundwater of Anar Plain. Anar plain is located in southeast part of Iran (west of Rafsanjan plain) between 55°,10’ to 56°eastern longitude and 30°, 30’ to 30°, 58’ northern latitude. This plain, stretching in a northwest- southeast direction, resembles a rectangle about 42 km in width and 82 km in length and is bounded by Badbakht- Kuh Mountain from the north and Dahaj-Sarduieh Mountain from the south (figure 1). About half of the plain in the north and west parts is occupied by barren salt playas. In addition to Anar and Koshkuieh towns, there are tens of villages in the plain which are mainly located in the medial part, where the Qantas supplying them with water emerge at the surface. Also, there are several asphalt roads in the plain, the main one connecting Kerman via Yazd to Tehran. Geologically, the Anar plain separates two zones of central Iran, namely Urimieh- Dokhtar in the south and flysh zone in the north. Badbakht- Kuh in the north is composed mainly of upper Cretaceous flyshes which are strongly tectonized and as a result of being low and narrow, has negligible role in recharging the alluvial aquifer of Anar plain. In contrast, the high and broad southern mountains which are mainly composed of volcanic rocks play a key role in recharging the aquifer.
