Tightening lead leaching standards for new drinking water fixtures – Opportunity for public comment

Update: In September 2020, the joint committee announced it revised the NSF/ANSI/CAN 61 standard.

On May 11, 2020, EDF and EWG jointly filed comments to NSF International supporting proposed changes to the NSF/ANSI/CAN 61 Standard.

We have a legacy of lead in our pipes, our paint, and our soil. These are the most significant sources of human lead exposure and, therefore, draw most of the attention and resources because they are costly to fix. It is also important to limit lead from new sources to avoid adding to that environmental burden. For that reason, EDF has sought, as part of our larger efforts, to reduce the amount of lead that leaches from new plumbing devices such as faucets and fountains.

Thanks to the leadership of California Assembly Member Chris Holden, a collaboration with Environmental Working Group, and a productively and collaboratively engaged Plumbing Manufacturers International (PMI), the trade association that represents the manufacturers that provide 90% of the plumbing products sold in the United States, we are seeing real progress from our efforts. We wanted to update you on two parallel, but related, developments:

  • A proposal to revise the current U.S. consensus national standard NSF/ANSI/CAN 61; and
  • California Assembly Bill AB 2060 to revise 116875 of the California Health and Safety Code.

These changes are needed because the current federal limit of 0.25% of lead by weight is insufficient to ensure that lead levels in drinking water are as low as possible, especially during the first few weeks of use before they are conditioned to the water. With these changes, buyers will be able to identify and purchase new devices that should meet the American Academy of Pediatrics recommended action level of one part per billion.

If all goes as anticipated, the more stringent NSF standard will be in place by the end of the year, manufacturers will begin the process of certifying products to the more protective lead limits, and there will be sufficient certified devices on the market in California to meet the anticipated demand from child care centers.

Lead from new “lead-free” brass faucets? An update on progress

By Tom Neltner, Senior Director, Safer Chemicals Initiative / Published: August 21, 2019

Tom Neltner, J.D. is the Chemicals Policy Director and Lindsay McCormick is a Program Manager.

[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.

Lead from a new “lead-free” brass faucet? More common than you’d hope

By Tom Neltner, Senior Director, Safer Chemicals Initiative / Published: November 6, 2018

Tom Neltner, J.D. is the Chemicals Policy Director and Lindsay McCormick is a Project Manager.

[pullquote]Until NSF/ANSI 61 standard is updated to reduce or eliminate lead leaching, users must extensively clean and flush new brass fixtures before use and make a short flush standard practice for older fixtures.[/pullquote]

During this past year, we undertook a pilot project to tackle the problem of lead in drinking water at child care facilities. As part of the effort, we collected 250 mL samples (about 8 ounces of water) from every drinking water fixture, as recommended in the Environmental Protection Agency’s (EPA) 3Ts guidance for schools and child care facilities. We replaced 26 faucets that exceeded our action level with new brass faucets that were labeled “lead-free” and complied with NSF/ANSI 61 standard for drinking water system components.[1] To our surprise, when we sampled the faucets a few days after replacement, the lead levels were higher– between 9 and 10 ppb – on three of the new faucets.

The increase left us scratching our heads. Federal law allows a drinking water fixture to be labeled “lead-free” if the amount of lead in wetted surfaces[2] averages less than 0.25% (down from the 8% limit between 1986 and 2014). However, it isn’t clear how much this amount might contribute to levels of lead in water. To explore this issue, we contacted the supplier who said its product was certified under NSF/ANSI 61 and, therefore, not likely the source. The supplier suggested the source could be from existing upstream valves or from disturbing the plumbing. We could not rule these other possibilities out.

A study by Virginia Tech’s Jeff Parks on three models of new NSF/ANSI 61 certified brass faucets found similar results and concluded that even newly manufactured “lead-free” faucets may not meet the 1 ppb limit that the American Academy of Pediatrics (AAP) recommends for schools.

EPA Updates its 3Ts Guidance for Reducing Lead in Drinking Water

By Lindsay McCormick / Published: October 16, 2018

Lindsay McCormick, is a Project Manager. Tom Neltner, J.D., is the Chemicals Policy Director.

Earlier this month, EPA released its updated 3Ts for Reducing Lead in Drinking Water Toolkit, which provides guidance for schools and child care facilities seeking to ensure children are safe from lead in water.  The new 3Ts – an update to the agency’s 2006 guidance – is now a web-based toolkit that includes modules, customizable templates, and factsheets.

Overall, the new toolkit is an improvement.  While the protocol itself is largely the same, the new toolkit is more user friendly and written for the non-technical audience, making it more likely that school and child care staff will use it.  EPA has also reframed the toolkit from “Training, Testing, and Telling” to “Training, Testing, and Taking Action” – placing more emphasis on the critical step of addressing lead sources than the previous version.  “Telling” is now integrated throughout the entire toolkit to highlight the importance of communication at every step. The agency has also developed a helpful flushing best practices factsheet, which is a topic that often causes considerable confusion.

In EDF’s June 2018 report on our pilot of 11 child care facilities, “Tackling lead in water at child care facilities,” we recommended EPA update its 2006 guidance to address four key gaps.  The agency has made progress on the two most important of those but leaves the other two unresolved. The most important change to the guidance is that the agency has removed the 20 parts per billion (ppb) action level and instead recommends action whenever there are “elevated lead levels.” While EPA does not define an elevated lead level, a deep dive into the appendix suggests that levels over 5 ppb warrant follow-up. The updated guidance also puts a greater emphasis on the identification of lead service lines (LSLs) and includes LSL replacement as a permanent control measure, though not as an explicit recommendation. Further, the agency did not update the protocol to deal with challenges posed by aerator cleaning and hot water heaters.  Below we explore each of these issues in further detail. Read More »

California becomes eighth state to require licensed child care centers to test and remediate lead in water

By Lindsay McCormick / Published: September 24, 2018

Lindsay McCormick, is a Project Manager. Tom Neltner, J.D., is the Chemicals Policy Director.

Today, California Governor Jerry Brown signed legislation that will better protect children in the state from the harmful effects of lead exposure. AB 2370, sponsored by Assembly Member Chris Holden and passed unanimously by state lawmakers, sets forth new requirements for licensed child care centers to test their drinking water for lead and use an alternative source if elevated lead levels are discovered.

EDF recently released a report highlighting child care facilities as a major gap in protecting kids from lead in water. As children under the age of six are most vulnerable to harm from lead, these facilities should be prioritized for reducing exposure. Compared to lead in schools, which has garnered national attention, child care has gone relatively unnoticed.

We applaud California for taking this important step to expand its school lead in water testing mandate to include child care. With the new legislation, California joins seven other states that have enacted such requirements. The state’s approach is largely similar to other states but it has an unusual feature – laboratories must directly report results to the state, which then will post the results online. Most of the details – including the definition of an elevated lead level in drinking water that warrants shutting off the fixture – are left to the state’s child care licensing agency to define in rulemaking.   Read More »

Illinois moves forward with critical rules to address lead in water at child care facilities

By Lindsay McCormick / Published: July 17, 2018

Lindsay McCormick, Project Manager.

Last week, EDF submitted comments to the Illinois Department of Children and Family Services (DCFS) on the state’s proposed rules for lead in water testing at licensed child care facilities. Our comments focused on what we learned from our pilot in 11 child care facilities, including 4 in the Chicago area.

Even at very low levels, lead can impair brain development, contributing to learning and behavioral problems as well as lower IQs. While national attention on lead in drinking water has spurred action in schools, few states have addressed lead in water in child care settings – even though these facilities serve children at younger, more vulnerable ages.

Illinois is one of seven states that EDF has highlighted in a previous blog for requiring lead in water testing in child care facilities. In January 2017, Illinois General Assembly enacted SB550, establishing a new set of requirements to address lead in drinking water in the state. Under the legislation, Illinois was required to adopt rules prescribing the procedures and standards to assess lead in water in licensed day care homes, day care centers, and group day care homes (herein after “child care facilities”).
