The current study included the Al-Buwair drinking water station located northwest of Mosul City in Nineveh Governorate/Iraq with the aim of evaluating the station's performance efficiency compared to the Iraqi standard specifications. Samples were collected starting from October 2023 until July 2024. Some physicochemical and biological properties were measured, including acidity (pH), electrical conductivity (EC), turbidity concentration (Turb.), total hardness (T.H), total basicity (Alk), total dissolved solids (TDS), sulfate ions (SO4^-2), chloride (Cl^-), and nitrate (NO₃) in addition to the total bacterial count (T.P.C). The results of the current study showed that all the studied properties conformed to the Iraqi standard specifications.
