The research deals with environmental pollution which has resulted from population activities affecting the quality of the streams of Al Hussayiya and Bani Hessen in Karbala Province by carrying out laboratory tests on water samples taken from the two streams The tests covered CaCO3,TS, SO4 -2 as well as Cl-1 The research results show an increase in some physical and chemical properties of the water of the two streams because the study of the physical properties has shown that CaCO3 rates of Al Hussayiya and Bani Hessen are high but within acceptable limits. However, the total salt rate of Al Hussayiya stream is very high exceeding the acceptable limits. On the other hand, the total salt rate of Bani Hessen stream shows a noticeable increase but it does not exceed the acceptable limits The study results show that the chemical properties of the water of the two streams are equal properties which tend to be weakly alkali because PH values of the water of the two streams range between (7.1 and 8 ). It is noticed also there is increase in the concentration of SO4 -2 of the water of the two streams, exceeding the acceptable natural limits because wastewater stations discharge waste to the Euphrates directly without any kind of treatment. It is worth mentioning that the Euphrates is the main water source for the water of the two streams while the concentrations of Cl-1are within natural limit, not , exceeding the acceptable natural limits. The researchers would like to point out the rise in salt rate in Razzaza Lake is because of water scarcity and because the Lake is not supplied with water from Habaniya Lake. Thus Razzaza Lake depends on the dead water stored within it. In addition, there is another reason which is the discharge of the main drainage is in the Lake.
