Evaluation of the Drinking Water Quality Index in Dibis District – Kirkuk

Abstract

In this study, a weighted mathematical model was utilized to evaluate the water quality of the filtration station in the Al-Dibs district. The assessment was conducted at five different sites from October 2023 to April 2024. Various characteristics of the water samples were measured, encompassing physical properties like turbidity, total suspended solids, total dissolved solids, and electrical conductivity. Additionally, chemical properties such as pH, total alkalinity, total hardness, calcium hardness, magnesium hardness, chloride, total nitrogen, and available phosphorus were analyzed. Bacterial properties, including total bacterial count, coliform bacteria, and fecal bacteria, were also assessed. The study monitored various sites along the Lower Zab River, including the raw water collection point, water pumping area, Oil Quarter, Diyarbakır Quarter, and Kolan Quarter. Results revealed unsatisfactory water quality at the raw water collection point, while excellent quality was observed at the other sites (2, 3, 4, 5). The water quality index rankings were as follows: 18.10, 17.61, 47.96, 30.40.These findings suggest that the water treatment station effectively produces water suitable for daily sanitary purposes.
