What role does the World Health Organization (WHO) play regarding water quality?

The World Health Organization (WHO) plays a crucial role in setting standards for safe drinking water. By establishing guidelines, the WHO helps ensure that drinking water is safe and contributes to overall public health. These guidelines are based on rigorous scientific research and are aimed at preventing waterborne diseases and protecting populations from health risks associated with poor water quality.

Setting standards involves defining permissible levels of various contaminants and pollutants in drinking water, which can vary by region and country based on local conditions and health needs. WHO's guidelines serve as a global reference that countries can adopt and adapt in their legal frameworks to safeguard public health.

In contrast, while conducting water testing may fall under the responsibilities of local authorities or specialized agencies, it is not the primary function of the WHO. Funding for water projects is typically managed by international development organizations or government bodies rather than WHO directly. Although the organization does engage in educating on water-related health issues, the formal setting of drinking water quality standards remains its most significant role in relation to water quality issues globally.
