What is the maximum contaminant level goal (MCLg) for suspected carcinogens?

The maximum contaminant level goal (MCLg) for suspected carcinogens is set at 0 mg/l. This standard reflects the principle that any amount of a substance that may cause cancer poses an unacceptable risk to human health. The goal of 0 mg/l emphasizes the intent to eliminate exposure to potential carcinogens in drinking water, even though practical limitations may exist in achieving this level in every circumstance.

The establishment of this standard is rooted in public health considerations, as the aim is to minimize cancer risk in populations served by public water systems. Health organizations and regulatory bodies prioritize protecting public health, leading to such stringent measures against substances classified as suspected carcinogens.
