In the United States, lead abatement activities are regulated by the United States Environmental Protection Agency. 

It is estimated that approximately 75 percent of homes built before 1978 contain lead paint. Lead-based paint is now known to be highly toxic and can cause permanent health consequences when ingested or inhaled. 

Lead abatement companies are governed by the EPA and the EPA requires and individuals and firms that conduct lead-based paint activities, including abatement, to be licensed. The lead abatement company, its supervisors, and all of the workers have to take classes and receive a certificate of completion. State agencies work with the EPA to enforce state and Federal laws.
