The public health community has tried for decades to show, through evidence-based research, that safe water, sanitation, and hygiene (WASH) and ...t medbox">clean cooking fuels that reduce household air pollution are essential to safeguard health and save lives in low-income and middle-income countries. In the past 40 decades, there have been many innovations in the development of low-cost and efficacious technologies for WASH and household air pollution, but many of these technologies have been associated with disappointing health outcomes, often because low-income households have either not adopted, or inconsistently adopted, these technologies.

The document focuses on household water treatment methods to ensure access to safe drinking water, particularly in areas with limited access to ...an class="attribute-to-highlight medbox">clean water sources. It highlights the importance of safe water, noting that contaminated water is a major cause of waterborne diseases such as diarrhea and cholera. Treating water at the household level is emphasized as an effective way to reduce health risks.
The document outlines several treatment methods, including boiling, which kills most pathogens; chlorination, which disinfects water by adding chlorine; filtration, which removes dirt and certain microbes using simple or advanced filters; and solar disinfection (SODIS), which involves exposing water in clear plastic bottles to sunlight for several hours to kill microbes. Additionally, it stresses the importance of safe water storage, such as using clean and covered containers to prevent recontamination, and practicing good hygiene, including regular handwashing and maintaining cleanliness around water sources.
By promoting these methods, the document aims to raise awareness and provide practical solutions for improving water quality at the household level, thereby reducing the spread of diseases and enhancing public health.

Guidance has been updated on a number of chemicals: asbestos, bentazone, chromium, iodine, manganese, microcystins, nickel, silver, tetrachloroethene and trichloroethene. Guidance has also been added for chemicals not previously assessed in the Guidelines: anatoxin-a and analogues, cylindrospermopsi...ns and saxitoxins. The new guidance on organotins has replaced the prior guidance focused on dialkyltins. 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.

Drinking-water quality regulations and standards developed or revised in accordance with this guidance will reflect the best practices identified in the WHO Guidelines for ...highlight medbox">Drinking-water Quality to most effectively protect public health. Moreover, the regulations and standards will consider local needs, priorities and capacities to ensure that they are realistic and appropriate. Topics covered include:
- Guiding principles
- Getting started
- Selecting parameters and parameter limits
- Setting out compliance monitoring requirements

When setting national drinking-water quality regulations and standards, many countries consider the WHO Guidelines for drinking-...ribute-to-highlight medbox">water quality (GDWQ). To better understand the extent to which the GDWQ are used and reflected in these standards, this global review summarizes information from 104 countries and territories on values specified in national drinking-water quality standards for aesthetic, chemical, microbiological and radiological parameters.
The information provided will support regulatory agencies and other key stakeholders to access and compare data when setting or revising national drinking-water quality regulations and standards.

Biodiversity and healthy natural ecosystems, including protected areas in and around cities, provide ecosystem benefits and services that support human health, including reducing flood risk, filtering air pollutants, and providing a reliable supply of clea...n drinking water. These services help to reduce the incidence of infectious diseases and respiratory disorders, and assist with adaptation to climate change. Access to nature offers many other direct health benefits, including opportunities for physical activity, reduction of developmental disorders and improved mental health.

The document "Proteksyon Maladi" focuses on preventing waterborne and hygiene-related diseases through practical measures. It emphasizes the importance of personal hygiene, including washing hands with soap and ...dbox">clean water before eating, after using the toilet, and during food preparation. Maintaining personal cleanliness is highlighted as a key step in preventing the spread of diseases.
Water safety is another critical focus, with recommendations to use treated or boiled water for drinking and cooking and to store water in clean, covered containers to prevent contamination. The document also addresses sanitation, encouraging the construction and maintenance of latrines to eliminate open defecation and promoting proper waste disposal to protect the environment and water sources.
Overall, the document serves as an educational resource, providing simple and effective strategies for communities to reduce the risk of diseases and improve public health through better hygiene, sanitation, and water safety practices.

WASH in schools during a cholera response is important due to the strong correlation between WASH and IPC. Not only can it impact the health and well-being of students and staff but also facilitate the potential spread of the disease via the congregation of children and adults from multiple househol...ds. Hygiene can often be more difficult to control with young children and therefore efforts to put in place systems to encourage good practices are essential.
To prevent the spread of cholera in schools, it is important to have clean and safe water sources, proper sanitation facilities, and good hygiene practices in place. This includes providing clean drinking water, hand-washing stations with soap, and education on hygiene and sanitation practices and implement Risk Communication and Community Engagement (RCCE) including dissemination of Information, Education and Communication materials (IEC).

Ethiopia met the MDG target for drinking water access with a unique and high degree of success. The magnitude of the country’s success in providing improved ...box">drinking water to nearly half of its population in 25 years despite its diversity, size, and challenges cannot be overstated. This case study documents the progress of the Ethiopian WASH sector from 1990 to 2015, and analyzes the impact of local systems created in Ethiopia to respond to water and sanitation challenges.

Nationally, Senegal met the MDG target for water supply access. It did this by engaging the public and private sectors to effectively invest and report on investments. It focused on larger population centers, less on remote regions of the country. I...ts achievements set the stage for more equitable and widespread service provision as the country now works to achieve the SDGs, requiring sustainable management of universal access. This case study documents the progression of the sector between 1990 and 2015, and analyzes the impact of local systems created in Senegal to respond to the water and sanitation challenge.

Democratic dispensation in 1994 created a political and social platform that reshaped life in South Africa. There was a surge in common belief that the inequity and wrong of Apartheid should and could be rectified. Equity of access to water and sani...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.
