Water standards refer to the established criteria and regulations that ensure the quality and safety of water for various uses, including drinking, recreational activities, and environmental protection. These standards are set by governmental and international organizations, such as the Environmental Protection Agency (EPA) in the United States or the World Health Organization (WHO). They define acceptable levels of contaminants, chemical substances, and biological indicators in water, ensuring that it is safe for human consumption and does not pose a risk to public health or the environment. Water standards also encompass guidelines for testing, monitoring, and treatment processes to maintain water quality and protect aquatic ecosystems. Compliance with these standards is critical for maintaining safe water supplies and preventing waterborne diseases and pollution.
