Proposed rule (reopening of comment period) on bottled water and the deferred final action on the proposed allowable level for the chemical di (2-ethylhexyl) phthalate (DEHP)
[Docket No. FDA-1993-N-0259
]

The Patient, Consumer, and Public Health Coalition-which includes nonprofit organizations that represent patients, consumers, scientists, and researchers-supports the FDA’s proposed rule for an allowable level of 0.006 milligrams/liter (6 parts of DEHP per billion parts of water (6 ppb)) for di (2-ethylhexyl) phthalate DEHP.

In animals, DEHP is a carcinogen, reproductive toxicant, and developmental toxicant.[1] Scientific evidence suggests that phthalates may be harmful to humans, and increase the risk of serious diseases such as cancer and reproductive problems. That is why the U.S. Department of Health and Human Services “has determined that DEHP may reasonably be anticipated to be a human carcinogen.”[2]

Research indicates that boys exposed to phthalates such as DEHP may be more likely to develop smaller genitals and incomplete descent of the testicles.[3] Boys who are born with undescended testicles are at higher risk of testicular cancer, a disease that primarily affects teenagers and young men. Studies by Harvard researchers have shown phthalates such as DEHP may alter human sperm DNA and semen quality.[4], [5], [6], [7] Based on these and other concerns, the Consumer Product Safety Improvement Act of 2008 banned the use of DEHP in children’s toys and products.

The implementation of this proposed rule has been deferred since 1993 on the grounds that the standard conflicted with an existing prior sanction for food and liquid packaging contact materials.  Since that time, based on information from industry, it appears that DEHP is “not being used in caps or closures for bottled water in the U.S.”[8] Also, the European Commission has stopped the use of DEHP in plastic caps, lids or metal caps, and the International Bottled Water Association has accepted the 6 ppb standard.

The FDA’s proposed rule of 6 ppb of DEHP in bottled water conforms with current industry standards, but it is crucial that this proposed rule become the regulatory standard because otherwise industry standards could change in the future, or some companies could ignore them.   If the 6 ppb standard is finalized, the FDA states that “bottled water products with DEHP levels above the finalized level will be misbranded if the products do not bear label statements of substandard quality.”8 This gives the FDA the power to enforce the 6 ppb standard, and will ensure that the public-especially children whose developing brains and bodies are more vulnerable to DEHP than adults-are protected from the adverse health effects of DEHP-tainted bottled water.

Because “the EPA has determined that DEHP is a probable human carcinogen,”2 we strongly support this proposed rule, which will ensure that neither adults nor children will be exposed to DEHP in their bottled drinking water.
