True or False: All public water systems must have chlorination facilities.

The statement that all public water systems must have chlorination facilities is true, as chlorination is a widely recognized disinfection method to ensure the safety of drinking water. The requirement for chlorination is based on the need to control microbial contaminants and prevent outbreaks of waterborne diseases. The Safe Drinking Water Act mandates that public water systems implement measures that effectively eliminate harmful pathogens.

While some small systems or alternative disinfection methods might be permitted under specific conditions, generally, the directive emphasizes that all public systems must have robust disinfection protocols in place, with chlorination being the most conventional method. Therefore, the answer accurately reflects the regulatory framework governing public water systems regarding the necessity of chlorination facilities.
