What term describes water that is not safe for human consumption?

The term that describes water that is not safe for human consumption is nonpotable water. This classification indicates that the water does not meet health guidelines for drinking due to the presence of contaminants, pathogens, or pollutants that could pose a risk to health. Understanding the distinction between potable (safe for drinking) and nonpotable water is important for public health and safety measures, particularly in situations where water supply may be compromised.

In contrast, pure water refers to water that is free from impurities and is chemically H2O, whereas distilled water is a type of purified water created through boiling and condensation, making it generally safe for consumption. Potable water is the correct term for water that is safe to drink and complies with health standards. Therefore, recognizing nonpotable water helps in identifying and managing water safety issues effectively.
