A chlorine level of 5.0 or higher typically indicates that the chlorine concentration in water, such as in a swimming pool or drinking water, is elevated. This level is generally considered high and may be used for shock treatments to eliminate contaminants like bacteria and algae. However, prolonged exposure to such high levels can be harmful to human health and can also lead to irritation of the skin and eyes. Maintaining appropriate chlorine levels (usually between 1.0 to 3.0 ppm for pools) is essential for safety and comfort.
