Abstract
Abkharvar Behbahan channel is 7 km long in Behbahan Plain located in arid and semi-arid area and it is limited in terms of water resources, therefore it is very important to preserve the quality of water resources and prevent them from being polluted. In order to investigate the pollution level of Abkharvar Cannel, sampling operations were carried out from 6 locations in the studied area. Water samples to determine the concentration of heavy elements As, Fe, Pb, Se, Zn, Mn, Cr, anions Cl-, SO42-, NO3-, CO3-, HCO3-, and cations Ca2+, Na+, Mg2+, K+, and important water quality parameters including Ph, EC and TDS were analyzed by ICP-OES, FAES, OAS, titration, drying and conductivity methods. The pH levels in all samples are within the WHO standard and the standard of wastewater discharged to surface water and agricultural uses. The concentration of SO42- anion and Mg2+, Na+, Ca2+ cations and important water quality factors including EC, TDS in the sample taken from the Maroon River (S6) is higher than the WHO drinking water limit. Geochemical data show that the water chemistry in the region is strongly influenced by factors such as the entry of industrial and human wastewater into this chanel, as well as the dissolution of carbonate rocks and evaporative sediments containing gypsum, calcite, and halite minerals along the Abkharvar Behbahan channel.
