What is the Maximum Contaminant Level (MCL) for the secondary standard for odor?

1 Threshold odor number (TON)
3 Threshold odor number (TON)
5 Threshold odor number (TON)
7 Threshold odor number (TON)

The correct answer is: 3 Threshold odor number (TON)

The Maximum Contaminant Level (MCL) for the secondary standard for odor in drinking water is set at a threshold of 3 Threshold Odor Numbers (TON). This standard is established to maintain water quality and ensure that the water is palatable to consumers. The threshold odor number is a measurement technique that assesses the intensity of odors in water samples, and the value of 3 TON indicates that the odor should not exceed this level to ensure the water's acceptability for consumption. Maintaining this standard helps water treatment facilities monitor and control potential issues related to unpleasant odors, which can affect public perception and trust in the water supply. While higher numbers reflect stronger odors, the set limit at 3 TON ensures that water remains appealing and acceptable for consumer use without raising concerns about its quality.
