Which statement best describes the impact of discharging industrial wastes on water uses?

• A. They do not affect aquatic life
• B. They can interfere with aquatic life, domestic use, and other uses if highly acidic or alkaline
• C. They always improve water quality
• D. They only affect drinking water

Answer: (B)

Industrial discharges can change water chemistry and introduce pollutants, so how water can be used depends on the pH and contaminant levels. When waste makes water highly acidic or alkaline, it stresses or kills aquatic life, and it can also hinder domestic uses like drinking, cooking, and cleaning, as well as other uses such as irrigation and recreation. This is why the statement describing potential interference with aquatic life, domestic use, and other uses when pH is extreme is the best description. The other options are incorrect because discharges do affect aquatic life, they do not typically improve water quality, and their impact isn’t limited only to drinking water.
