ANN ARBOR, MICH. – NSF International, an independent public health organization that tests and certifies a wide range of plumbing and drinking water treatment products, strongly supports the passage of the Reduction of Lead in Drinking Water Act on Jan. 4, which significantly reduces the amount of lead allowed in plumbing products that contact drinking water.

NSF International applauds the government for harmonizing federal legislation with recently enacted state requirements and NSF Standards. In 2008, Annex G was incorporated into NSF/ANSI Standard 61: Drinking Water System Components - Health Effects and includes requirements limiting weighted average of lead content in plumbing products to 0.25%, the same as required by this new federal legislation. This legislation (which will take effect Jan. 4, 2014) now makes the federal law consistent with California lead-free legislation passed in 2006, amends the Safe Drinking Water Act’s definition of lead-free and limits the maximum content of lead in plumbing devices so it’s consistent with the lead content requirements of NSF Standards.

Plumbing devices already certified to NSF Standard 61, Annex G fully comply with the lead-content requirements of this newly passed Act. A list of compliant products can be found on NSF’s website, http://www.nsf.org/Certified/Lead_Content/.

“We applaud Congress and the Administration for taking this long-awaited step to harmonize this requirement across the country, which will help protect the public from exposure to lead in their drinking water,” said Bob Ferguson, NSF International vice president of water systems. “We are pleased that the new national requirement for lead in plumbing devices will be equivalent to the requirements in NSF/ANSI national standards. NSF is prepared to support this effort and help address this growing public health concern by continuing to test and certify drinking water products that conform to these new lead-free requirements.”

NSF has developed several standards that limit the amount of lead and other contaminants that can migrate from water contact materials into water. In 1988, the EPA replaced its own Drinking Water Additives evaluation program with NSF standards that were developed, in part, with EPA funding. Most states and public utilities require manufacturers making products that come into contact with water to have them tested to verify they meet NSF’s national standards.

Products covered in NSF/ANSI Standard 61 include pipes and related products; protective and barrier materials (including cements/coatings); joining and sealing materials (including gaskets, adhesives, lubricants); process media (including carbon, sand, zeolite, ion exchange media); mechanical devices (including water meters, in-line valves, filters, process equipment); mechanical plumbing devices (faucets, drinking fountains, and components); and potable water materials (non-metallic materials).

A copy of Annex G as adopted in NSF/ANSI 61 – 2008 is available on NSF’s Web site.

A new standard, NSF/ANSI 372: Drinking Water System Components - Lead Content, has recently been adopted, which contains the procedures to verify the lead content of drinking water products. This standard is referenced in Annex G of NSF/ANSI 61 as the methodology to determine lead content compliance. Products certified to NSF/ANSI 372 demonstrate compliance with lead content requirements only while certifications to NSF/ANSI 61 Annex G demonstrate compliance with both lead content requirements and for potential leachate release against drinking water standards.
