Water Quality of Al-Kufa River, Tap water and Reverse Osmosis (R.O.) water in some neighborhoods passing through Al-Najaf City, Iraq, was evaluated for drinking using the standards of World health organization. Water samples were collected from fourteen sites during six months from September 2015 to February 2016. Conductivity (EC), pH, hardness, alkalinity and total dissolved solids (TDS) were determined. It was noticed that some studied parameters of river and tap water were more than drinking water standards, while studied parameters of R.O. water were within acceptable standards.
