Share of the population without access to an improved water source, 2020. Global access to clean water is a significant global challenge that affects the health, well-being, and development of people worldwide. While progress has been made in recent years, millions of people still lack access to safe and clean drinking water sources.
Drinking water quality standards describes the quality parameters set for drinking water. Water may contain many harmful constituents, yet there are no universally recognized and accepted international standards for drinking water. Even where standards do exist, the permitted concentration of individual constituents may vary by as much as ten ...

The contamination of water remains a significant issue because of unsanitary social practices that pollute water sources. Almost 80% of disease in developing countries is caused by poor water quality and other water-related issues that cause deadly health conditions such as cholera, malaria, and diarrhea. [1]
Although water quality is usually sampled and analyzed at laboratories, since the late 20th century there has been increasing public interest in the quality of drinking water provided by municipal systems. Many water utilities have developed systems to collect real-time data about source water quality.
Typically, fresh water is defined as water with a salinity of less than 1% that of the oceans – i.e. below around 0.35‰. Water with a salinity between this level and 1‰ is typically referred to as marginal water because it is marginal for many uses by humans and animals. The ratio of salt water to fresh water on Earth is around 50:1.
Public water supply systems are crucial to properly functioning societies. These systems are what supply drinking water to populations around the globe. [1] Aspects of service quality include continuity of supply, water quality and water pressure. The institutional responsibility for water supply is arranged differently in different countries ...
accessibility to water services (access to sanitation and drinking water); safety and quality (water quality index, global flood frequency); management (World Governance Index, transboundary legal framework, transboundary political tension). [86] Scientists have been working on ways to measure water security at a variety of levels.
