In water quality regulation, what does MCL stand for?

Maximum Contaminant Level is the largest permissible amount of a contaminant allowed in drinking water that regulators enforce to protect public health. This standard is set by the U.S. EPA under the Safe Drinking Water Act and is enforceable, with monitoring and penalties if exceeded. It’s designed to be achievable through treatment and monitoring while still safeguarding health, and it often works alongside the non-enforceable MCLG, which is the health goal. For example, arsenic has an MCL of 10 parts per billion. The other terms don’t fit regulatory usage: a minimum contaminant level would imply a lower bound, which isn’t how standards are described; a “maximum contamination limit” or “maximum contaminant listing” aren’t standard regulatory terms.
