Description
At permanent and temporary installations, disinfection by chlorination, chloramination, or other means will be applied to all water for potable uses, except from municipal or private water supply sources which conform to the bacteriological criteria. Refer to CFR 40 for additional treatment beyond disinfection. Disinfection should be applied to all water before use. Additional treatment should be provided to naturally contaminated water. Special decontamination treatment should be applied to chemically contaminated water in addition to regular treatment.
