There are two (2) types of contaminants that are present in an untreated water, which is aesthetic and health-related contaminants.
-
True
-
False
Correct Answer
A. TrueExplanation
The statement is true because untreated water can contain both aesthetic and health-related contaminants. Aesthetic contaminants refer to substances that affect the taste, odor, or appearance of water, such as minerals, algae, or organic matter. Health-related contaminants, on the other hand, can include bacteria, viruses, parasites, chemicals, or heavy metals that can pose a risk to human health if consumed. Therefore, it is important to treat water to remove these contaminants and ensure its safety for drinking and other uses.Rate this question:
