Abstract

The current study was conducted to show the presence of heavy elements and pathogenic microorganisms
and the quality and validity of water and sediments in the household water tanks at the city center of Nasiriyah
and their suitability for household and drinking uses from the autumn 2019 to summer 2020. Physical,
chemical and biological checks of water were carried out in three stations, two selected stations located in
the center of Nasiriyah city (1- Erido 2- Al-Salhiya), and the third station, Al-Asalah, which is located in
Al-Shatrah district. Samples were collected monthly and quarterly, with three replications per station. The
study included measuring the temperature of air and water, the pH, salinity, turbidity, dissolved oxygen DO,
and the Biological Oxygen Demand BOD5. In addition, the concentration of four heavy elements (cadmium,
copper, lead and zinc) in the water was measured in its entirety. The study included measuring the TOC
content and mixing the sediment, and also the concentration of four heavy elements (cadmium, Copper,
lead and zinc) are completely sediment. The study also included investigation of bacterial contamination by
detecting the total numbers of aerobic bacteria, the number of coliform bacteria, the number of fecal coliform
bacteria, the numbers of fecal and Pseudomonas Aeruginosa bacteria in the water and sediments. The results
of the physical and chemical tests of water in the study stations showed that the values of air and water
temperatures ranged between (20.1-40) C and (17.50-30) C, respectively, and that the water of the studied
stations was basic as the pH values ranged between (7.00-8.20) The salinity values ranged between (485-
837) ppm, and the turbidity values were between (2.50-6.79) NTU. The dissolved oxygen values ranged
between (5.39-8.01) mg/liter, and the Biological Oxygen Demand BOD5 were between (2.93-8.5) mg/liter.
