Estimation of Bacterial Content of Water from some Wells South of Samarra City

Abstract

The study was conducted in the south of Samarra, and the city of Dhuluiya with its suburbs south of the city of Salah al-Din for the period from 15/11/2021 to 15/4/2022. The study included conducting a field study to estimate the bacterial content of water of some wells south of Samarra. Water samples were taken for six wells in the areas where the study was carried out. The results of the study show that the air temperature in the study area during the collection of samples was characterized by wide seasonal ranges amounting between (4) -39) degrees Celsius, while the temperature ranges of the groundwater samples reached (19-30) degrees Celsius. The total number of bacteria Total Plate Count (T.P.C) ranged between (75-335) CFU / ml, where the highest number of bacteria in Well 6 is in March, and the lowest number is in Well 2 in April. While the number of Total Coli from Bacteria (T.C.B) ranged between (7.4-1100) cells/100 ml, the highest value was in the well 1.2 in the month of February, and the lowest value was in the well 2.3 in the month of March.
