During fresh fruit and vegetables (FFV) production, water is used for a variety of purposes. Even the water was conventionally treated and disinfected, it may still potentially contain human pathogens, albeit at low concentrations. A risk assessment, appropriate to the national or local production c...ontext, should be conducted to assess the potential risks associated with a specific water source or supply in order to devise the appropriate risk mitigation strategies.
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.

At its 48th session of Codex Committee on Food Hygiene (CCFH), the Committee noted the importance of water quality and safety in food production and processing. CCFH requested the Food and Agriculture Organization of the United Nations
(FAO) and the World Health Organization (WHO) to provide guidan...ce for those scenarios where the use of “clean water” (i.e. water that does not compromise the safety of the food in the context of its use) was indicated in Codex texts and on
where it is appropriate to use “clean water”. In particular, guidance was sought for the use of irrigation water and “clean” seawater and on the safe reuse of processing water.

The National Institute for Transforming India (NITI) Aayog has developed the Composite Water Management Index (CWMI) to enable effective water management in Indian states in the face of extreme water stress. The Index and this associated report are expected to: (1) establish a clear baseline and ben...chmark for state-level performance on key water indicators; (2) uncover and explain how states have progressed on water issues over time, including identifying high-performers and under-performers, thereby inculcating a culture of constructive competition among states; and, (3) identify areas for deeper engagement and investment on the part of the states. Eventually, NITI Aayog plans to develop the index into a composite, national-level data management platform for all water resources in India.

Disinfection of drinking-water supplies has been one of the most significant public health advancements of the last century with respect to reducing waterborne disease.
Although chlorine has been used as the disinfectant of choice for public drinking-water supplies for the past century, a numbe...r of emerging or alternative compounds are used or are being considered for the disinfection of drinking-water.
This series reviews the state of the knowledge on the application, efficacy and toxicity of bromine, iodine and silver as drinking-water disinfectants.

In September 2021, the UN and its partners presented a response plan to mitigate the impact of the water crisis in northern and north-east Syria which requested US$200 million to assist up to 3.4 million of the over five million people estimated to be affected by the water crisis in northern Syria b...etween September 2021 and February 2022. Under the auspices of the 2022-2023 Syria Humanitarian Response Plan, this updated water response plan presents the most recent needs based on latest forecasts and is a continuation of the earlier plan presented in 2021. It covers the needs from all response modalities/areas1 for Syria, aims to assist 5 million people until December 2022 and requests $226.2 million.

Long-term planning for an adequate and safe supply of drinking-water should be set in the context of growing external uncertainties arising from changes in the climate and environment. The water safety plan (WSP) process offers a systematic framework to manage these risks by considering the implica...tions of climate variability and change.

This guide is intended for people involved in the management and operation of small- to mediumsized organized water supply systems. The content has been developed with particular consideration for operational-level personnel with responsibility for chlorination (for example, water treatment plant op...erators and technicians). The material presented within this guide may also be relevant for engineers and representatives from public health, local government, non-governmental organizations, as well as any other individuals supporting water safety planning activities for the supply of safe drinking-water.
Part 1. Chlorination principles: Describes key chlorination concepts, providing a knowledge foundation for the implementation of effective chlorination practices.
Part 2. Chlorination practices: Describes the practical application of the concepts presented in Part 1, including calculations and procedures for safe and effective chlorination of drinking-water supplies.

Chapter 5: A Community Guide to Environmental Health
The purpose of the report is to present some first recommendation for the development of Myanmar ecological quality criteria using the system of the EU Water Framework Directive (EU WFD) as baseline, with main focus on the characterization and classification processes. As background for the recommen...dations we first give an overview of the main water use categories in Myanmar. 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.
