The report was published from the World Health Organization/ United Nations Children’s Fund (WHO/UNICEF)’s pilot project to test a method for the rapid assessment of the quality of drinking-water in six countries;; including Jordan;; China;; Ethiopia;; Nicaragua;; Nigeria and Tajikistan. This assessment report aims to develop a tool that would support WHO/UNICEF’s joint program in strengthening the monitoring efforts of the global access to safe drinking water. The analysis of the report is based on the water samples and statistical data that were collected from 1600 drinking water supply sites in 67 clusters. The report finds that drinking water quality is generally high in the distribution network of Jordan and national standards for bacteria complies with the WHO guideline values. It also identifies the sanitary risk factors for Jordanian water supplies including the presence of sewer lines;; old pipes and failure to properly maintain household storage tanks.
