Pathogen occurrence
Rolling revision of the WHO Guidelines for Drinking-water Quality
Pathogen occurrence is included in the plan of work of the rolling revision of the WHO Guidelines for Drinking-water Quality.
Background
Information on pathogen concentrations in source waters provides important input to development of WSPs, performance targets, etc. The Guidelines for Drinking-water Quality Final Task Force meeting (Geneva, 2003) recommended that a database on pathogen occurrence be created. In addition, a document entitled Occurrence of Pathogens in Surface Water has been prepared.
Expected end-product(s)
- Publication of the document Occurrence of Pathogens in Surface Water
- Exploration of the possibility of a database jointly managed with IWA.
Progress to date
The Guidelines for Drinking-water Quality Working Group meeting (Geneva, 2004) agreed to a plan of work. There had not been significant progress by the time of the Guidelines for Drinking-water Quality Working Group meeting (Geneva, 2005).
