Water quality regulations are rules set by governments to ensure that water is safe for drinking, swimming, and other uses. These regulations establish acceptable levels of pollutants and contaminants in water sources, such as rivers, lakes, and groundwater. Agencies like the Environmental Protection Agency (EPA) in the United States monitor and enforce these standards to protect public health and the environment. These regulations often require regular testing of water supplies and may include guidelines for wastewater treatment. By adhering to these standards, communities can help prevent waterborne diseases and maintain healthy ecosystems. Compliance with water quality regulations is essential for safeguarding both human health and natural resources.
