ANSI/NSF Standard 372 low-lead certification

Federal efforts to control lead concentrations in drinking water began in 1974 with the passage of the Safe Drinking Water Act (SDWA). Under the SDWA, drinking water system components must qualify as “lead-free” by complying with federal requirements. In January, 2011, the Reduction of Lead in Drinking Water Act defined stricter “lead-free” requirements by reducing the maximum lead content levels needed for compliance. These provisions will take effect in January 2014.

Concurrently, a number of states have moved quickly over the past few years to enact regulation aimed at reducing the lead content of drinking water system components. More restrictive state limits are already in effect in California and Vermont, and new lead content restrictions are set to take effect in Maryland next year.

To assist manufacturers in demonstrating compliance to the low-lead laws, UL offers certification to ANSI/NSF 372.
