What is the purpose of establishing Maximum Contaminant Levels (MCLs) for drinking water?

• A. To improve aesthetic qualities
• B. To protect public health
• C. To reduce treatment costs
• D. To enhance distribution efficiency

Answer: (B)

Establishing Maximum Contaminant Levels (MCLs) for drinking water serves the critical purpose of protecting public health. MCLs are regulatory limits set by government agencies that define the maximum permissible amount of specific contaminants allowed in drinking water supplies. These levels are determined based on scientific research and health risk assessments, ensuring that water remains safe for consumption. By setting MCLs, public health officials are able to mitigate the risk of waterborne diseases and health issues that can arise from the consumption of contaminated water. Ensuring that water quality meets these standards helps safeguard communities from potential hazards associated with pollutants, such as heavy metals, microbes, and chemical substances. Overall, MCLs are a vital component of water quality standards and play a fundamental role in maintaining public health and safety in relation to drinking water supplies.
