Work in progress and drafts for the ongoing revision of the guidelines
The rolling revision of Guidelines for Drinking-water Quality presently includes preparation of the following:
Aspects of Microbial Quality:
- Protecting groundwater for health: managing the quality of drinking-water sources
- Protecting surface water for health: managing the quality of drinking-water sources
- Legionella and the prevention of legionellosis
- Drinking water treatment efficiency and the occurrence of pathogens in surface waters
- Safe piped water: Managing microbial water quality in piped distribution systems
- Risk assessment: cryptosporidium
- Safer drinking-water: improving the assessment of microbial safety
- Pathogenic Mycobacteria in water
Aspects of Chemical Quality
- "Additives" (materials and chemicals used in production and distribution of drinking-water)
- Chemical safety of drinking-water: assessing priorities for risk management
- Fluoride in drinking-water
Aspects of "Protection and Control" of Drinking-water Quality
- Surveillance and control of water supply in urban areas
- Water quality for travellers
- Safe desalination
- Water safety plans
The way we organize the rolling revision of the Guidelines is described in Policies and Procedures for Rolling Revision of Guidelines for Drinking-water Quality (presently in review).
