In 1991 the Environmental Protection Agency (EPA) published a regulation known as the Lead and Copper Rule (LCR). The LCR established a requirement for public drinking water systems classified as either community or non-community non-transient to routinely monitor for lead and copper.
Also identified in the LCR are action levels for lead and copper. An action level is a threshold above which a water system must take steps to ensure safety and protect public health. For lead and copper, the action level is deemed to have been exceeded when more than 10% of the samples tested during a collection period show concentrations at or above the 15 ppb for lead and 1300 ppb for copper and is called a 90th percentile exceedance.
