If a pool exhibits a clear greenish tint to the water, what could be a potential cause?

• A. Presence of algae
• B. Presence of copper
• C. High chlorine levels
• D. Low pH levels

Answer: (B)

A clear greenish tint to pool water is typically indicative of the presence of copper. Copper can enter pool water from various sources, such as using copper-based algaecides or metal runoff from nearby structures. When copper levels rise, the water may take on a green hue due to the way it interacts with light. In contrast, the presence of algae (as suggested in another choice) usually results in a more opaque or murky green color, along with other indicators like a slimy texture or increased debris. High chlorine levels would generally cause water to appear clearer and would not typically result in a greenish tint, while low pH levels can lead to other issues such as corrosion or scale formation, but they do not directly cause a green color in the water. Thus, copper is the primary concern when observing a clear greenish tint in pool water.
