Action Level The concentration of a contaminant, which, if exceeded, triggers treatment of – other requirements, which a water system must follow. Treatment Technique (TT) a treatment technique is a required process intended to reduce the – of a contaminant in drinking water. Maximum Contaminant Level (MCL) The highest level of a contaminant that is allowed in – drinking water. MCLs are set as close to the MCLGs (see definition below) as feasible using the best available treatment technology. Maximum Contaminant Level Goals (MCLG) The level of a contaminant in drinking water – which there is no known or expected risk to health. MCLGs allow for a margin of safety.
