What Are the Safe Levels for Carcinogenic Contaminants?
Safe levels for carcinogenic contaminants are often determined by agencies like the Environmental Protection Agency (EPA). For example: - Arsenic: The MCL for arsenic is 10 parts per billion (ppb). - Radon: The EPA recommends mitigating radon in water if levels exceed 4,000 picocuries per liter (pCi/L). - Nitrate: The MCL for nitrate is 10 parts per million (ppm).
