"Studying the Percentage of Water Pollution in the City of Fallujah and Determining the Efficiency of Filtering Plants in Purifying Drinking Water "

Abstract

Abstract This study was conducted on the water of the city of Fallujah in Anbar Governorate for the period from November 2020 to February 2021. It studies the levels of water pollution and the studied samples were taken from the water of the river, the station and home. The study included the measurement of a number of physical and chemical properties of water represented ( PH, electrical conductivity, chloride and the concentrations of sodium, calcium, potassium, lithium, and barium ions, as well as measuring the concentrations of some heavy elements (copper, cadmium, iron, lead, chromium, cobalt, zinc, and nickel) comparing them with the standard specifications. The results of the study showed that the electrical conductivity values, the pH values and the chlorides were in conformity with the international standards, and that the concentration of sodium, calcium, potassium and lithium ions was in conformity with the standard specifications. Also the barium ion concentration was high, while the concentrations of some heavy elements such as copper, cadmium, Iron, lead, cobalt and zinc were identical. According to international standards, the concentration of chromium and nickel was high and had a toxic effect. A biological study was also conducted on the sample, where types of bacterial isolates were found in the river water. As for the tap water, after treatment, some bacteria species were found and had no satisfactory effects.
