Is there current federal legislation that defines lead free?
Yes. The Safe Drinking Water Act (SDWA) was originally passed by Congress in 1974 to protect the nation’s public drinking water supply. The law has been amended in 1986 and 1996. Currently, the SDWA states that “lead-free” plumbing may contain up to 8 percent lead. For more information, go to http://www.epa.gov/safewater/sdwa/index.
