Pathogens and Infectious Diseases Practice Test

Turbidity is purely aesthetic and cannot affect microbial survival, disinfection, or the likelihood of disease transmission.

Particles can shield microbes from disinfectants and indicate runoff contamination, making treatment less effective and exposure more likely.

Particles always sterilize water by scraping microbes, so higher turbidity should reduce infections in all cases.

Turbidity increases water sweetness, attracting pathogens that require sugar and therefore guaranteeing infection after drinking.
