What is the Maximum Contaminant Level (MCL) for nitrite in drinking water?

• A. 0.5 mg/L
• B. 1 mg/L
• C. 2 mg/L
• D. 3 mg/L

Answer: (B)

The Maximum Contaminant Level (MCL) for nitrite in drinking water is set at 1 mg/L. This standard is established by the Safe Drinking Water Act to protect public health by limiting the amount of contaminants in drinking water. Nitrite can pose significant health risks, particularly to infants, as it can interfere with the oxygen-carrying capacity of blood. The MCL of 1 mg/L is based on scientific research and risk assessments that identify the threshold at which nitrite’s presence in drinking water becomes hazardous. By adhering to this standard, water treatment facilities can ensure that the water supplied to consumers is safe for use and consumption. The values provided in the other choices do not align with the established guidelines set forth by regulatory bodies and, thus, are not considered safe limits for nitrite in drinking water.
