Abstract
Water is only naturally pure occurring inorganic fluid in the universe but most of the surface water sources are no more inorganic, since the generated wastewaters polluting the freshwater sources and rendering them unfit for various purpose. Though, the problem of water pollution is worldwide, it is surprising that it draws the attention of scientists only when it becomes hazardous for human health. With this view, an attempt was made to evaluate the quality of water in Kor river in Fars province, Iran. Water samples from different locations in the course of Kor river were collected to check the suitability of water for human use. The parameters like, Cl–, alkalinity, TSS, TDS, pH, EC and temperature were measured. The amount of them was compared with standard threshold. Some stations showed that water was just suitable for agriculture for some products like wheat and barley. The self purification model of river is shown for EC and alkalinity of water.
