What is the action level for copper in drinking water?

• A. 0.5 mg/L
• B. 1.0 mg/L
• C. 1.3 mg/L
• D. 1.5 mg/L

Answer: (C)

The action level for copper in drinking water is established at 1.3 mg/L. This is a crucial standard set by regulatory agencies, including the Environmental Protection Agency (EPA), to protect public health. If the concentration of copper in drinking water exceeds this level, it indicates the necessity for water systems to take action to reduce the copper levels. This is particularly important because elevated copper levels can pose health risks, especially for vulnerable populations, including children and pregnant women. Therefore, the identification of 1.3 mg/L as the action level reflects extensive research regarding the health effects of copper exposure and serves as a benchmark for ensuring safe drinking water quality.
