Which treatment technology is not specified by the Surface Water Treatment Rule?

The Surface Water Treatment Rule (SWTR), established by the Environmental Protection Agency (EPA), sets forth requirements aimed at ensuring the safety of drinking water derived from surface water sources. This rule explicitly requires certain treatment technologies to deal with various pathogens and contaminants.

Chlorination is specifically mentioned as a common method of disinfection to eliminate pathogenic organisms. Filtration is clearly outlined as a necessary treatment procedure to remove particles and microorganisms from water. Ultraviolet (UV) treatment is also included within the regulations as an approved method for disinfecting drinking water.

Chloramine disinfection, however, is a form of disinfection that is not specifically required under the Surface Water Treatment Rule. It can be utilized as an alternative method in water treatment but is not mandated as a treatment technology like chlorination, filtration, or UV treatment. Consequently, while chloramine can be effective, it does not fall under the specific requirements set forth by the SWTR, distinguishing it from the other treatment options outlined in the regulation.
