Protecting surface water for health provides a structured approach to the assessment and management of drinking-water quality related risks in surface-water catchments. The publication will support the development and application of water safety planning where source-water protection is a key element in the provision of safe drinking-water. Protecting surface water for health embraces the concept put forward by Goal 6 of the SDGs to “Ensure availability and sustainable management of water and sanitation for all”, recognizing that the protection of water quality and water-related ecosystems contributes to public health protection.
This publication synthesizes the current knowledge on quantitative microbial risk assessment (QMRA) to facilitate its application in the practice of water supply, water reuse and water recreation to support the management of risks associated with faecal pathogens in the water-related context. Guidance is provided to support the successful implementation of QMRA with key aspects including: the role of interaction between risk managers and risk assessors; interpretation of scientific data including uncertainty; and interpretation of quantitative results. Many examples including six full case studies are described.
JULY 2016 - The UN-Water Global Analysis and Assessment of Sanitation and Drinking-Water (GLAAS) is entering a new strategy period after successfully completing three full cycles and a pilot. With the new strategy, some things have stayed the same, but some things have changed as GLAAS evolves looking towards the future and the Sustainable Development Goals. The 2017 report, to be released prior to the Sanitation and Water for All High Level Meeting in April 2017, will feature finance while still covering elements of all traditional GLAAS topics (governance, monitoring, human resources).
16 October 2015 -- WHO in coordination with PAHO provides technical advice to national authorities in Brazil and to the International Olympic Committee on matters of public health with visitors and athletes attending the Olympic Games. The Olympic athletes will be in contact with the water in Rio De Janeiro for the 2016 Olympic Games for sailing, rowing, canoeing and swimming events. WHO recommends that national authorities follow the “Guidelines for Safe Recreational Water Environments” to protect public health and ensure that water quality testing and sanitary inspections are carried out and the source of any pollution is addressed.
WHO works on aspects of water, sanitation and hygiene (WASH) where the health burden is high and where evidence-based interventions could make a major difference.
