Which of the following statements about filtration is true?

Filtration is a crucial process in water treatment primarily aimed at removing impurities, including pathogens, sediments, and particulate matter, which directly relates to public health. By effectively reducing harmful microorganisms and contaminants from water, filtration plays a significant role in preventing waterborne diseases, ensuring that the water is safe for consumption.

This necessity for public health is emphasized in regulations and guidelines that govern water quality standards in many areas, including those outlined by organizations like the TCEQ. The filtration process not only enhances safety but also contributes to the overall quality of the water that communities rely on. As a result, the statement that filtration is necessary for public health accurately reflects its importance in maintaining safe and clean drinking water.
