According to the EPA, lead at any level can be harmful. The EPA has a maximum contamination goal of zero; however, they have not stated how or when they are going to enforce the regulation if it is amended. [83] During the summer of 2018, Washington DC issued a boil water advisory to all of its residents in the North East and North West areas.
Under the LCR, if tests show that the level of lead in drinking water is in the area of 15 ppb or higher, it is advisable—especially if there are young children in the home—to replace old pipes, to filter water, or to use bottled water. EPA estimates that more than 40 million U.S. residents use water "that can contain lead in excess of 15 ppb".

Maximum contaminant levels (MCLs) are standards that are set by the United States Environmental Protection Agency (EPA) for drinking water quality.
