The Safe Drinking Water Act requires the U.S. Environmental Protection Agency to determine the level of contaminants in drinking water at which no adverse health effects are likely to occur with an adequate margin of safety. According to the EPA, these non-enforceable health goals, based solely on possible health risks, are called maximum contaminant level goals (MCLGs). The Environmental Protection Agency Maximum Contaminant Level for lead is set at 0.015, with a minimum reporting limit of 0.0005. If lead is found at any water outlet at levels above 20 parts per billion, EPA recommends taking immediate action to reduce lead.
High levels of lead in drinking water can cause health problems. Lead is most dangerous for pregnant women, infants, and children under six years old. Exposure to high level of lead during pregnancy can contribute to low birth weight and developmental delays in infants. In young children, lead exposure can lower IQ levels, affect hearing, reduce attention span, and hurt school performance. At very high level, lead can even cause brain damage.
For information about water quality and sampling for lead at home, contact your local water supplier or state drinking water agency.
