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.
