How can the safety of drinking-water be monitored globally? What definitions would be meaningful and assist decision-makers in the process of improving the drinking-water situation in the world? What research and development efforts are needed to come up with a rapid, reliable and cost-effective way of measuring water quality indicators locally and reporting on them at the global level. Since the decision in 2000 to adopt a method based on nationally representative household surveys, the WHO/UNICEF Joint Monitoring Programme for Water Supply and Sanitation (JMP) has explored options to report on the safety of drinking-water supplies. In this connection, between 2002 and 2008 the rapid assessment of drinking-water quality (RADWQ) project was designed, implemented and documented in a number of pilot countries where the quality of drinking-water from improved sources was evaluated.

During 2004 and 2005 the Republic of Tajikistan and five other countries participated in a World Health Organization/United Nations Children’s Fund (WHO/UNICEF) pilot project to test a rapid, low-cost, field-based technique for assessing water quality. The project was named the Rapid Assessment of Drinking-Water Quality (RADWQ), and its purpose was to develop a tool that would help the WHO/UNICEF Joint Monitoring Programme monitor global access to safe drinking-water. The RADWQ methodology is based on the UNICEF Multiple Indicators Cluster Surveys and uses cluster sampling across a country to select individual drinking-water sources for testing. The number and types of parameters used to test the drinking-water sources will depend on the extent of the survey and on local potential health hazards. The output of a RADWQ survey is a snapshot of drinkingwater quality for each improved source tested. In Tajikistan, four field teams visited 1620 sample sites in 53 clusters over a period of six months (from October 2004 to April 2005). The samples were taken from four broad areas (Khatlon; Rayons under direct Republican Subordination (RRS) & Dushanbe; Sughd; and Gorno-Badakhshan
Autonomous Oblast), and from two improved water-supply technologies (utility piped supplies and protected springs). Using portable field kits, water samples were analysed for the following parameters: thermotolerant coliforms, faecal streptococci, pH, turbidity, residual chlorine, appearance, conductivity, arsenic, nitrate, fluoride and iron. In addition, samples were taken from 160 households (or ca. 10% of the total sample size), to analyse the deterioration of water quality during distribution and storage.[authors abstract]
