Children are uniquely vulnerable to environmental contaminants. Their bodies are still developing, they eat, drink, and breathe more per pound of body weight than adults, they have lungs that are still developing, and they may be more exposed to hazards and unaware of how to protect themselves. Lead exposure can cause serious damage to children's developing brains. There is no safe level of lead. Most of children's lives are spent in schools when they are not at home. Lead in drinking water is an issue most schools have not been required to address or report. Parents should learn about lead in the drinking and cooking water in their children's schools and care centers. After discussing the health effects of lead on children and pregnant women, this paper presents the Healthy Schools Network's 5-Point Plan for lead in school drinking water and discusses what state officials, school officials, and parents can do. A list of resources is provided.
