Final answer:
Drinking water is purified using both physical methods like filtration and chemical methods like disinfection to ensure safety. The most common chemical treatment is disinfection with chlorine, whereas physical methods include filtration and ultraviolet disinfection. Therefore, the given statement is TRUE.
Step-by-step explanation:
Drinking Water Treatment Methods
Both physical and chemical methods are used to treat and purify drinking water, which is an essential process for ensuring safe drinking water. The most common drinking water treatment method involves disinfection, typically through the addition of chlorine or other disinfectants to kill bacteria and germs. At home or in emergencies, water can be purified by simply pouring the water through a filter, a physical method that relies on passing the water through a fine mesh to remove particulates. Chemical methods like flocculation involve adding chemicals to water to help remove small particles, thereby improving water clarity and safety. For instance, the Ultraviolet Disinfection method applies a physical, chemical-free process to effectively reduce parasites and other microorganisms in the water, though it does not remove dissolved organics or inorganic compounds. Municipal water treatment can include several steps, depending on the quality of the source water, including coagulation, sedimentation, and filtration, ensuring that the water is safe for community use.
