ant explicit consideration in policies and regulations.
These Guidelines, specifically tailored to small water supplies, build on over 60 years of guidance by the World Health Organization (WHO) on drinking-water quality and safety. They focus on establishing drinking-water quality regulations and standards that are health based and context appropriate; on proactively managing risks through water safety planning and sanitary inspections; and on carrying out independent surveillance. The guidance is intended primarily for decision-makers at national and subnational levels with responsibility for developing regulatory frameworks and support programmes related to these activities. Other stakeholders involved in water service provision will also benefit from the guidance in this document.
Designed to be practical and accessible, these Guidelines offer clear guidance that is rooted in the principle of progressive improvement. State-of-the-art recommendations and implementation guidance are provided, drawn from a comprehensive evidence review and established good practices. Additionally, case examples are provided from countries and areas around the world to demonstrate how the guidance in this publication has been implemented in practice in a wide variety of contexts.
Together with WHO’s 2024 Sanitary inspection packages – a supporting tool for the Guidelines for drinking-water quality: small water supplies, these Guidelines update and supersede WHO’s 1997 Guidelines for drinking-water quality. Volume 3: surveillance and control of community supplies. Key changes to this updated publication include a greater focus on preventive risk management and a broader range of small water supplies covered, including those managed by households, communities and professional entities.

We then provide preliminary suggestions for typology criteria and indices for assessing ecological status in lakes and rivers in Myanmar. The typology factors and physico-chemical parameters are based on common used factors in the EU countries. The biological elements include phytoplankton and aquatic macrophytes for lakes, and benthic invertebrates for rivers.

Since the 48th session of Codex Committee on Food Hygiene (CCFH) noted the importance of water safety and quality in food production and processing, FAO and WHO has undertaken the work on this subject. This report describes the output of the third in a series of meetings, which examined appropriate and fit-for-purpose microbiological criteria for water used with fresh fruit and vegetables. The advice herein will support decision making when applying the concept of fit-for-purpose water for use in the pre- and post-harvest production of fresh fruit and vegetables.

Step-by-step risk management guidance for drinking-water supplies in small communities.
Guidance has been updated on a number of chemicals: asbestos, bentazone, chromium, iodine, manganese, microcystins, nickel, silver, tetrachloroethene and trichloroethene.

With these updates, the guideline values for tetrachloroethene and trichloroethene have been revised while new guideline values for cylindrospermopsins, manganese, microcystins, and saxitoxins have been established .
Updated information on cyanobacteria has been included, introducing an alert level framework for early-warning and to guide short-term management responses. Guidance has also been updated in the sections on adequacy of water supply, climate change, emergencies, food production and processing, and radiological aspects, particularly on managing radionuclides when exceeding WHO screening values and guidance levels.

This publication presents the World Health Organization’s (WHO’s) sanitary inspection packages. These packages update the sanitary inspection forms in WHO’s 1997 Guidelines for drinking-water quality. Volume 3: surveillance and control of community supplies. With more than 25 years of practical experience with the application of sanitary inspections, these packages have been developed from a comprehensive evidence review and established good practices.

tation were obvious targets for improvement. In 1994, an estimated 14–15 million South Africans were without access to an improved water supply, while close to 21 million - more than half of the population at that time - did not have access to improved sanitation facilities. These problems were most severe in poorer rural areas. The water and sanitation sector became unified by the vision of universal access for all South Africans. This case study documents the progression of the sector between 1994 and 2016, and analyzes the impact of local systems created in South Africa to respond to the water and sanitation challenge.
