Children's Rights to Privacy

The EPA is concerned about protecting children's privacy. We encourage parents and teachers to be actively involved in their children's Internet explorations. It is particularly important for parents to provide guidance to their children relative to providing personal information online. We encourage children to email us if they need assistance with the site or have environmental science questions. Contact information they may provide is used solely to personally respond to them, and is not used to create profiles of any type. Providing personal contact information is entirely optional, and we specifically ask that children obtain their parents' permission before providing any information online - at our site or any other site.

  the name of the domain you use to access the Internet.
This information will be used on a limited basis for statistical and historical purposes only. Unless it is specifically stated otherwise, no additional information will be collected about you.
