Which term describes the aspects of water quality that include depth, turbidity, currents, and dangerous aquatic life?

• A. Depth and turbidity, currents, and dangerous aquatic life
• B. pH level only
• C. Physical Water Quality
• D. Common Diseases

Answer: (C)

The aspects described—depth, turbidity, currents, and dangerous aquatic life—are all about the water’s physical state and safety in the environment. They relate to how the water looks, how it flows, and what physical hazards might be present, rather than to its chemical makeup (like acidity) or to biological disease itself. That’s why they fall under Physical Water Quality: it groups the observable, non-chemical attributes that describe the water’s physical condition and its suitability for use or safety. In contrast, a measure like pH is a chemical property, and diseases are biological concerns, not physical attributes.
