Learn how to identify lead-free certification marks on drinking water system and plumbing products PDF Corrosion is a dissolving or wearing away of metal caused by a chemical reaction between water and your plumbing.
A number of factors are involved in the extent to which lead enters the water, including: One requirement of the LCR is corrosion control treatment to prevent lead and copper from contaminating drinking water.
Corrosion control treatment means utilities must make drinking water less corrosive to the materials it comes into contact with on its way to consumers' taps. Learn more about EPA's regulations to prevent lead in drinking water.
Rather, it is intended to let you know about the most significant and probable health effects associated with lead in drinking water.
Is there a safe level of lead in drinking water? The Safe Drinking Water Act requires EPA 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. These non-enforceable health goals, based solely on possible health risks, are called maximum contaminant level goals MCLGs.
EPA has set the maximum contaminant level goal for lead in drinking water at zero because lead is a toxic metal that can be harmful to human health even at low exposure levels.
Lead is persistent, and it can bioaccumulate in the body over time. Young children, infants, and fetuses are particularly vulnerable to lead because the physical and behavioral effects of lead occur at lower exposure levels in children than in adults.

A dose of lead that would have little effect on an adult can have a significant effect on a child. In children, low levels of exposure have been linked to damage to the central and peripheral nervous system, learning disabilities, shorter stature, impaired hearing, and impaired formation and function of blood cells.
It is important to recognize all the ways a child can be exposed to lead. Children are exposed to lead in paint, dust, soil, air, and food, as well as drinking water.
If the level of lead in a child's blood is at or above the CDC action level of 5 micrograms per deciliter, it may be due to lead exposures from a combination of sources. Infants who consume mostly mixed formula can receive 40 percent to 60 percent of their exposure to lead from drinking water.
Children Even low levels of lead in the blood of children can result in: Behavior and learning problems.Your browser is out-of-date!
