Evaluation of some physical, chemical and bacteriological characteristics of fish ponds in Kirkuk City

The present study aimed to conduct a field study on the water ponds in different areas of Kirkuk city. For the purpose of evaluating the water quality for four selected areas, which included water before the pond (wells water) and water inside and outside the ponds (fish ponds). December until 7/31/2021 in July. The study included measuring physical properties such as (water temperature, electrical conductivity, dissolved solids) and chemical properties such as (pH, dissolved oxygen, biological oxygen requirement, chemical oxygen requirement, total basicity, total hardness, calcium and magnesium hardness, chlorides, Sulfates, phosphates, nitrates, total nitrogen, proteins) and the percentage of bacterial contamination was also studied, which included (the total number of bacteria (Total Plate Count (TPC), the total number of Escherichia Coli Bacteria and the number of Fecal Coliform Bacteria). The results were compared with the international determinants and specifications of water standards
