Welcome to our detailed exploration aimed at demystifying the concerns and facts surrounding Per- and polyfluoroalkyl substances (PFAs) in sparkling water. With the rise in popularity of sparkling water as a go-to beverage for hydration and enjoyment, it’s become more important than ever to understand exactly what we are putting into our bodies.
PFAs have been the subject of much debate and research, and this guide seeks to provide a comprehensive look at these substances, their implications on health, and the steps you can take to ensure your safety.
Understanding PFAs in Sparkling Water
PFAs, or Per- and polyfluoroalkyl substances, are a group of man-made chemicals utilized for their water and grease-resistant properties. These substances are pervasive and have been detected in various environments, raising concerns about their presence in our water supply, including sparkling water. Consumer Reports conducted a thorough investigation, testing 47 bottled waters, comprising 35 noncarbonated and 12 carbonated options, for PFAs and heavy metals.
The federal government provides voluntary guidance on PFAs, recommending that the combined amounts of two specific PFAs compounds remain below 70 parts per trillion (ppt). Some states have implemented stricter limits, ranging from 12 to 20 ppt. The International Bottled Water Association advocates for PFAs levels below 5 ppt for any single compound and 10 ppt for more than one. However, some experts argue for an even lower threshold, suggesting a cutoff for total PFAs levels at 1 ppt.

PFAs in Carbonated Water
The investigation by Consumer Reports revealed that many carbonated water products contained measurable amounts of PFAs. The carbonation process, the source water’s PFAs content, or the water treatment methods used by certain brands could contribute to these levels. All the carbonated water products tested fell below legal limits for heavy metals, and none had arsenic levels above Consumer Reports’ recommended maximum of 3 parts per billion (ppb).
Brands’ Responses and Actions
Consumer Reports reached out to all companies with PFAs levels above 1 ppt. La Croix and Canada Dry assured that their products’ PFAs levels were well below current standards. Topo Chico, with the highest PFAs levels in the tests, expressed commitment to making improvements for future stricter standards. Nestlé, producing Poland Spring and Perrier, reported undetectable PFAs levels in their recent tests and expressed support for federal PFAs limits.
PFAs in Non-Carbonated Water
Most noncarbonated water products tested had detectable PFAs levels, though only two—Tourmaline Spring and Deer Park—exceeded 1 ppt. Tourmaline Spring asserted that their PFAs levels were below the limits set by the IBWA and all states. Nestlé, the manufacturer of Deer Park, claimed their most recent tests showed undetectable PFAs levels.
Heavy Metals and Safety Concerns
All noncarbonated waters tested had heavy metal levels well below federal safety limits, except for Starkey Spring Water, owned by Whole Foods. This brand had arsenic levels just shy of the federal limit of 10 ppb and more than three times Consumer Reports’ recommended level of 3 ppb. Whole Foods emphasized their commitment to providing safe, high-quality spring water, ensuring compliance with FDA standards for heavy metals.
Exposure to PFAs is associated with a range of health issues, including cancer, hormonal disruption, and developmental problems in children. The pervasive nature of these substances and their ability to linger in the environment almost indefinitely make them a significant concern for public health. Understanding the potential health risks associated with PFAs is crucial for making informed choices about water consumption.
The Current State of PFAs Regulations
As of now, the U.S. Environmental Protection Agency (EPA) has established a health advisory level for two specific PFAs compounds, PFOA and PFOS, at 70 parts per trillion (ppt) combined. However, it is important to note that these advisory levels are not enforceable regulations but rather guidelines to assist federal, state, and local officials in protecting public health.
Some states have taken matters into their own hands, implementing stricter PFAs limits in the absence of federal regulations. For example, New York has set a maximum contaminant level (MCL) of 10 ppt for PFOA and 10 ppt for PFOS, while New Jersey has established MCLs of 13 ppt for PFOA and 13 ppt for PFOS.
Efforts are underway to address the PFAs issue at both the federal and state levels. In 2020, the EPA announced its PFAs Action Plan, outlining steps the agency is taking to understand and mitigate PFAs contamination. This includes developing new analytical methods to detect PFAs in water, conducting toxicity assessments for various PFAs compounds, and evaluating the potential for establishing enforceable drinking water standards.
At the state level, legislatures are passing laws to ban or restrict the use of PFAs in certain products, require PFAs testing in drinking water, and establish cleanup standards for PFAs-contaminated sites.
How to Check PFAs Levels in Sparkling Water?
Checking PFAs levels in sparkling water can be challenging, as this information is not always readily available to consumers. However, there are steps you can take to find out more about the PFAs content in your sparkling water:
- Contact the Manufacturer: Reach out to the sparkling water brand directly and ask them about their PFAs testing practices and results. Brands that are committed to safety should be willing to share this information with consumers.
- Look for Brand Transparency: Choose brands that are transparent about their water sources, treatment processes, and testing results. Brands that provide detailed information about their practices on their website or product labels are generally more trustworthy.
- Check for Third-Party Certifications: Look for certifications from reputable organizations like NSF, which indicate that the product has been tested and meets safety standards.
- Stay Informed: Keep yourself updated on the latest research and news about PFAs in drinking water. Organizations like the Environmental Working Group (EWG) provide valuable resources and databases that can help you make informed choices.
