[Update: On 10/23/19, the NSF committee responsible for revising NSF 61 tentatively agreed to tighten the limits on lead leaching from new faucets and drinking fountains. The committee will move forward with a formal vote and, if approved, will receive public comment on the proposed changes.]
Last year, we discovered and reported in a blog, that some new brass faucets that meet existing standards and are labelled “lead-free” can still leach significant amounts of lead into water in the first few weeks of use. Here, we answer some questions that have come up and provide an update on efforts to revise the NSF/ANSI 61 standard to better protect and inform consumers.
Last November, the committee responsible for revising the NSF/ANSI 61 standard convened a group to consider an optional certification for faucets that meet a more protective limit. A study of more than 500 models of faucets showed that 73% of faucets leach less lead into water and can meet a limit that is five times more protective for children. However, currently there is no easy way to identify these “lower lead” models. The optional certification would enable consumers, schools, and child care facilities to identify and purchase faucets that leach less lead to drinking water.
Unfortunately, as described later in this blog, representatives of the brass faucet manufacturers have worked to block the optional certification. As of August 2019, the committee has not decided whether to move forward with a proposal for the optional certification to receive public notice and comment. If the committee fails to move forward, we anticipate that some major retailers that sell brass faucets and other major buyers such as school districts and builders would use their leverage to set higher standards in their purchasing specification that favors models performing better on the NSF/ANSI 61 lead leaching test.
