Abstract
The current research includes conducting a biological study in the study stations, which diagnosed some indicators of bacterial contamination of water and included (the total number of plate count total bacteria, the total number of total coliform bacteria and fecal coliform bacteria) Faecal, (Coliform, and the study began in October 2020 until March 2021).
