What does “MCL” refer to?
A. MCL stands for “Maximum Contaminant Level.” In general terms, the MCL is the maximum amount of a contaminant that is allowed in drinking water to ensure that the water is safe for people to drink. Water meeting the MCL standards is considered safe to drink, although some people, such as those with severely compromised immune systems, children, and the elderly, may have special needs. If your water system is classified as a community water system, the system is required to produce an annual water quality report (Consumer Confidence Report or CCR). This report is required to list any contaminants found in excess of the MCL. Additionally, your system is also required to inform you of the steps taken to remedy the situation.
