ABSTRACT

This study aims to evaluate the quality of treated (outlet) water samples taken from Al-Qurna and Lubkhah water stations at Al- Quwayiyah governorate. These water samples were subjected to physico-chemical analyses in laboratories of Ministry of water and electricity at Al-Quwayiyah governorate branch. The results of physico-chemical tests showed that the values of pH, Nitrate, Iron and Free Chloride were within the specifications of drinking water issued by the Saudi Arabia Standards Organization (SASO, 2000) and World Health Organization standards (WHO, 2006). On the other hand, the values of Total Dissolved Solids, Conductivity and Total Hardness were higher than the SASO (2000) and WHO (2006). Accordingly, these water sources obtained from Al-Qurna and Lubkhah water stations at Al- Quwayiyah governorate are not use as a drinking water due to the higher values of Total Dissolved Solids, conductivity and total hardness.

Keywords: Al-Quwayiyah governorate, Al-Qurna and Lubkhah water stations, drinking water, Physico-chemical analyses.
