Getting lead out of brass and bronze food equipment

Tom Neltner, J.D. is the Chemicals Policy Director.

Many people may not be aware that lead is still added to brass and bronze used to make drinking water faucets and food equipment like coffee brewers and more. This is problematic because lead can leach into the water and beverages from the equipment – putting consumers at risk. As part of EDF’s efforts to reduce exposure to lead from all sources, we have advocated to stop this use of the heavy metal.

Last June, our three-year effort yielded results when the committee responsible for the national consensus standard for plumbing devices, known as NSF/ANSI/CAN 61, made its lead leaching standard five times more protective for endpoint devices – from 5 to 1 parts per billion. Endpoint devices are faucets, drinking water fountains and other devices installed within the last one liter of water distribution systems in a building. For all other plumbing devices, lead is limited to the amount added to the device’s material, 2500 parts per million (ppm) [1], and leaching limit does not apply.

This fall, we turned our attention to lead leaching into drinking water from food equipment such as ice machines, coffee brewers, teapots, and water heaters. We have submitted petitions to NSF International and to the Food and Drug Administration (FDA) asking them to prohibit use of lead in brass and bronze commonly used in these devices.

For food equipment, we leveraged the more protective safety standards for food contact substances in the Food Additives Amendment of 1958. These standards require that additives not be used unless there is a reasonable certainty of no harm from their intended use after taking into account related substances in the diet. It also prohibits use of carcinogens. Lead is unsafe under both these restrictions because it is a carcinogen and no safe threshold has been found for lead in the blood to prevent neurologic development harm in children and heart disease in adults.

It’s time to eliminate lead from tin coating and solder on metal food cans

Tom Neltner, J.D. is the Chemicals Policy Director.

In October 2019, we reported finding canned foods had a surprising number of samples with lead based on the Food and Drug Administration’s testing results. Almost half of the 242 samples had detectable lead, including a staggering 98% of 70 canned fruit samples.

We suspect that the high lead detection rates are a result of lead in the tin – either added to make an alloy or as a contaminant – used to coat the steel or join steel pieces together in the cans. This lead can then leach from the coating or solder into the food. Light-colored fruits and fruit juices would be more likely to have lead contamination based on a report indicating they are commonly packaged in tin-coated steel cans without a synthetic coating on the inside isolating the food from the tin. The lead detections in the other canned products in FDA’s study could have resulted from flawed synthetic coatings.

In December 2020, EDF and ten health, consumer, and environmental groups[1] petitioned FDA to ban the use of lead in food contact materials such as tin. We also included that FDA should presume that lead was intentionally used when levels in food contact materials are at or above 100 parts per million (ppm) and provided an option for the agency to specifically authorize the use only if:

  • The part of the food contact article that contains added lead does not contact food under intended conditions of use; or
  • No lead migrates into food from the food contact article under intended conditions of use.

Our petition demonstrates that, because lead is a carcinogen that is unsafe at any level in the blood, its use in tin coatings and solder for food cans should be expressly prohibited. The agency posted the petition for public comment and must make a decision how to proceed by June 2021. There is no deadline for comments, but it is best to submit them by April 1 so they can influence the agency’s decision.

Implications of Home Depot’s lead-based paint settlement and $20 million penalty

Tom Neltner, J.D.is Chemicals Policy Director.

In January 2017, the outgoing Obama Administration undertook a criminal investigation of Home Depot for alleged violations of the Lead-Safe Renovation, Repair and Painting (RRP) Rule. Last month, the Environmental Protection Agency (EPA) signed a proposed civil consent decree with Home Depot committing the company to establishing a comprehensive set of detailed procedures designed to ensure compliance with the rules and protect customers from lead poisoning.  The company also paid a fine of more than $20 million in civil penalties – more than any other under the Toxic Substances Control Act.

A federal court will consider accepting the proposed consent decree after reviewing public comments received by January 20, 2021.

The proposed consent decree is important because it:

  • Serves as a reminder that companies that subcontract work to others are responsible for complying with the RRP rule; and
  • Provides a comprehensive template for other retailers and general contractors to adopt to ensure compliance.

The settlement also alerts us of troublesome implications of a new federal policy that limits violators’ ability to direct some of the fines to affected communities for activities such as lead poisoning prevention projects.

ASDWA provides new recommendations to states and utilities for lead service line inventories

Tom Neltner, J.D., Chemicals Policy Director

The Association of State Drinking Water Administrators (ASDWA) released a new white paper to help states and utilities develop more useful inventories of lead service lines (LSLs). The paper builds on guidance the organization issued in August 2019. ASDWA partnered with BlueConduit to leverage that firm’s experience developing a statistical model for Flint, Michigan that accurately predicted which service lines were made of lead, galvanized steel, plastic or copper.

The guidance is timely as EPA prepares to finalize its Lead and Copper Rule revisions. We anticipate those revisions will require utilities to develop – and make public – inventories that identify the location of each service line made of lead or when the material is unknown and may be lead. Utilities would also be required to notify customers annually if they have a lead or unknown service line. Customers who buy a home and open a new water account would also be notified in the first bill.

The ASDWA/BlueConduit white paper encourages utilities to use five principles to best characterize the uncertainty in their inventories:

  1. Ensuring clean data management and organization;
  2. Not accepting all historical records as truth;
  3. Conducting a representative randomized sample of unverified service lines;
  4. Being transparent in public outreach and reproducibility; and
  5. Demonstrating accuracy on “hold-out sample.”

New study: Lead reduction prevented up to 99,000 heart disease deaths in 2014 alone

Tom Neltner, J.D., Chemicals Policy Director

[pullquote]EPA needs to estimate reduced heart disease deaths when it evaluates the merits of four upcoming rules addressing lead in water, paint, and air.[/pullquote]

In 2018, we blogged on a study by Lanphear et al. that linked adult blood lead to a jaw-dropping 400,000 heart disease deaths annually. We called on federal regulatory agencies to give serious consideration to this and similar studies to develop a model they can use to quantify the socioeconomic benefits of potential regulatory changes designed to reduce adult exposure to lead. In June, 2019, the Environmental Protection Agency (EPA) successfully completed the necessary peer review of a model. The review was completed too late to be incorporated into the agency’s proposed revisions to its Lead and Copper Rule (released October 2019), but we applied the analysis to estimate that replacing all lead service lines in the nation over ten years would provide societal benefits of more than $205 billion – and called on EPA to consider the benefits when finalizing the rule.

Last week, Abt Associates, EPA’s contractor[1] who developed the initial peer-reviewed model, published a refined model in Environmental Health Perspectives and used it to estimate that between 34,000 and 99,000 cardiovascular disease (CVD)-related deaths were avoided in 2014 due to reduced adult blood lead levels from 1999 to 2014. The analysis reports that between 16% and 46% of the overall reduced CVD deaths during those 15 years was attributable to reduced lead in adult blood. Read More »

FDA’s Failure on Food Chemical Safety Leaves Consumers at Risk of Chronic Diseases

Tom Neltner, J.D., Chemicals Policy Director and Maricel Maffini, Ph.D., Consultant

Update: FDA published the citizen petition upon receipt on 9/23, and is requesting public comment.

More than 60 years ago, Congress enacted legislation requiring the Food and Drug Administration (FDA) and the food industry to evaluate the cumulative effects of substances in the diet that have related health impacts when assessing the safety of chemical additives. In our decade of analyzing FDA and industry actions, we have been increasingly concerned that both have ignored this requirement. To figure it out, we investigated all safety determinations contained in Generally Recognized as Safe (GRAS) notifications voluntarily submitted by food manufacturers to FDA since the program began in 1997. We looked at GRAS notices because they are publicly available and because FDA rules explicitly require that food manufacturers include in the notice an explanation of how they considered the requirement. If there was an omission, it would be more easily noticeable.

We found that in only one of 877 GRAS notices did a food manufacturer consider the cumulative effect requirement in a meaningful way. And we found no evidence that the agency either recognized this single attempt to follow the law or had objected to the omissions in the 876 other notices. This failure has significant consequences for public health, particularly for communities who already face significant health and socio-economic disparities, and for children, who are uniquely susceptible to dietary exposures to multiple chemicals.

For this reason, EDF joined with other health, environmental, and consumer groups to file a formal petition to demand FDA and food manufacturers start following the law. The petition requests specific changes to rules designed to reinforce the existing requirement and make it easier to verify compliance. Still, given the lack of transparency in agency reviews, success still largely depends on FDA and the food industry taking seriously the mandate and the food safety implications.
