Multiple Choice

What are the two main reasons for treating wastewater?

Explanation:
Wastewater treatment mainly aims to protect people and the environment. The core purpose is to prevent disease by destroying or inactivating pathogens, and to prevent harm to waterways and ecosystems by removing a wide range of pollutants. This means reducing microorganisms that can cause illness and cleaning out contaminants such as organic matter, nutrients, solids, and toxic chemicals so the treated water is safe for communities and compatible with receiving waters. While odor control and energy efficiency can be benefits of treatment, they aren’t the fundamental reasons for performing it. Limiting the focus to nutrients is too narrow, since pathogens and many other pollutants must also be addressed. And aiming to eliminate all pathogens completely isn’t practical in real-world treatment; the goal is to reduce risk to safe, regulatory-approved levels through proper treatment and disinfection.

    Decent, but I wished there were more in-depth explanations for some topics. A few questions felt off, and I had to supplement with notes. Still, the random questions helped with confidence on days I studied and reviewed with flash cards.
