Abstract :

Sarein city from cities of Ardabil province is in Northwest of Iran that it has 9 hot springs. Water of springs used in spa and discharge in Kenzagh River that native inhabitants used for agriculture and livestock. Therefore, investigation the origin and type of spring water and the concentration of heavy metal and toxic elements in springs are essential. For investigation the type and source of water and waste water, sampled and some chemical and physical characteristic of the cation and anions main and heavy metal were measured. The results show that the amount of H2S and CO2 gases in the hot springs Sarein is high (8.16, 44 mg/l). According to Piper diagram, water of the hot springs is chloride and bicarbonate sodic type. The anion triangle diagram shows that the hot springs in the area Sarein peripheral and shallow waters is rich in carbonates. According to the Ficklin chart all springs are almost neutral. Maximum amount of detergent determined in 1 station that is 5.23 mg/l and Maximum amount of BOD is 1590 mg/l in 2 stations.
