What is the MCL for color in drinking water?

10 color units
15 color units
20 color units
25 color units

The correct answer is: 15 color units

The maximum contaminant level (MCL) for color in drinking water is set at 15 color units. This guideline is established to ensure that tap water is aesthetically acceptable for consumers. Color in drinking water can arise from various sources, including the presence of organic matter, minerals, and other substances. High levels of color can indicate deterioration in water quality and can affect consumer acceptance, leading to concerns about the overall safety of the water. Maintaining the MCL at 15 color units helps water utilities manage treatment processes and communicate effectively with the public regarding water quality standards. By adhering to this limit, water suppliers can ensure that the water is both safe to drink and visually pleasing, contributing to public confidence in the drinking water system.
