What led to the government getting involved in the treatment of water?

The government became involved in the treatment of water primarily due to public health concerns and the need to ensure safe drinking water. Contaminated water sources led to widespread waterborne diseases, prompting regulatory measures. The establishment of agencies, such as the Environmental Protection Agency (EPA) in the United States, aimed to set standards for water quality and oversee treatment processes. Additionally, growing industrialization and urbanization highlighted the necessity for organized water management systems to protect the environment and public health.
