As more and more people become aware of the potential health risks associated with chemicals in our daily lives, the question of “Does Soda Have PFAS?” has gained prominence.
Soda is unlikely to have significant PFAS levels, but contamination could occur from water sources, bottles, or industrial emissions. Some bottled water brands contain PFAS, and soda may also be susceptible. Currently, mandatory testing for PFAS in soda is not required, and no specific PFAS testing data is available.
In this article, we’ll delve into the world of per- and polyfluoroalkyl substances (PFAS) to understand their presence in various products, including soda, and the potential health risks associated with them. We’ll also cover the measures taken by authorities and manufacturers to ensure the safety of the sodas we all drink and love.

Does Soda Have PFAS?
PFAS are a group of human-made chemicals that have been in use since the 1940s. They are used in a variety of applications, including non-stick cookware, stain-resistant fabrics, and firefighting foams.
While it’s true that PFAS have been detected in some brands of bottled water and food packaging materials, there is no definitive evidence to suggest that forever chemicals are present in sodas.
However, it’s important to know that PFAS can end up in soda through indirect contamination, such as:
- Contaminated water used to produce soda
- PFAS-containing packaging materials such as bottles and caps
- Industrial emissions near production facilities
Unraveling the PFAS Mystery: Is Your Soda at Risk?
As consumers become increasingly concerned about the presence of harmful chemicals in the products they consume, the potential for PFAS in soda has become a topic of discussion. In this section, we will explore the water source for soda, how manufacturers treat water, and any reported cases of PFAS detected in soda.
Tracing the Journey: Where Does Soda Get Its Water From?
The water source for soda production varies depending on the location of the manufacturing facility. Manufacturers often use one or more of the following water sources:
- Municipal water supply: Many soda manufacturers rely on the local municipal water supply, which is treated and regulated by local authorities.
- Natural springs: Some manufacturers may use water from natural springs, which is typically considered pure and free from contaminants.
- Groundwater wells: In some cases, manufacturers may have their own groundwater wells to source water for soda production.
Regardless of the source, manufacturers are responsible for ensuring that the water used in their products meets the safety standards set by regulatory agencies.
Ensuring Purity: How Soda Manufacturers Treat Water to Eliminate Contaminants
Fortunately, soda manufacturers treat the water used in their products to ensure its purity and safety. The water treatment process typically involves several stages, including:
- Filtration: Water is passed through filters to remove particles, sediment, and other impurities.
- Disinfection: Chemicals, such as chlorine or ozone, or ultraviolet light are used to kill bacteria and other microorganisms that may be present in the water.
- Dechlorination: If chlorine is used for disinfection, it is removed to prevent any residual taste or odor in the final product.
- Reverse osmosis or activated carbon filtration: These processes remove any remaining impurities, including contaminants like PFAS, to ensure the water meets the required quality standards. Read my article about brands of bottled water that use reverse osmosis filtration.
Manufacturers may also conduct regular testing of the water to monitor for the presence of contaminants, including PFAS, and take corrective action if necessary. Currently, the US EPA does not require PFAS testing of soft drinks.
PFAS in Soda: Fact or Fiction? Examining Reported Cases
There have been no widely reported cases of PFAS detected in soda at levels that pose a significant risk to human health. Although it’s possible for trace amounts of PFAS to be present in soda due to indirect contamination, the levels are likely to be well below the guidelines set by regulatory agencies.
Manufacturers and regulatory bodies are continuously working together to monitor and limit PFAS exposure. By implementing strict quality control measures, sourcing water from safe sources, and treating water to remove contaminants, soda manufacturers aim to ensure the safety of their products for consumers.
How Can PFAS Get into Soda
1. PFAS in water source
PFAS can contaminate drinking water sources, and this may be a concern for soda manufacturers using water from such sources. In recent years, there have been cases where high levels of PFAS were found in public water systems, leading to widespread concerns about water safety.
Contaminated water sources are the reason several brands of bottled water have PFAS in them. It stands to reason that sodas could also be affected in the same way.
In the absence of testing, it is not possible to rule out a PFAS-contaminated water source for your favorite brand of soda.
2. PFAS in bottles and packaging
It is a well-known fact that PFAS is in a lot of the food packaging materials we use. This is related to food packaging that provides grease, oil, and water resistance.
For bottled soda, there are three packaging components that may be sources of PFAS contamination:
- Bottle or can: Bottles are typically made of plastic, glass, or aluminum. Cans are made of aluminum. None of these materials are known to contain PFAS.
- Cap: Generally, caps are made out of high density polyethylene (HDPE) and polypropylene (PP). Caps for glass bottles may also be made of aluminum or steel. These materials do not contain PFAS.
- Cap liner: The cap liner is made of 3-ply foam, polyethylene foam, pressure-sensitive foam liner, induction liner, polyvinyl, poly seal, Teflon PTFE, foil and plastisol. Teflon is made from PFAS compounds and may impart low levels of this contaminant to the soda
3. Industrial emissions
Emissions from industries that use PFAS, such as manufacturing facilities or wastewater treatment plants, can lead to contamination of the environment, including air, soil, and water. If a soda production facility is located near such industries, there may be an increased risk of PFAS contamination.
Given the widespread production of soda manufacturing in the US, it is possible that a bottling plant could be located near a PFAS-emission source. This is a potential source of PFAS-contamination in soft drinks.

Health Risks Associated with PFAS Exposure
The potential health risks associated with PFAS exposure have been a topic of ongoing research and debate. According to the Environmental Protection Agency and the Centers for Disease Control and Prevention (CDC), exposure to high levels of PFAS can lead to adverse health effects, including:
- Hormonal disruption
- Increased cholesterol levels
- Impaired immune function
- Low infant birth weights
- Increased risk of cancer
However, it’s crucial to note that these health effects are generally linked to long-term exposure to high levels of PFAS, which is unlikely to occur through the consumption of soda alone.
Regulations and Measures to Limit PFAS Exposure
Given the potential health risks associated with PFAS exposure, several measures have been taken by regulatory bodies and manufacturers to limit PFAS presence in food and beverages.
Regulatory Measures
Various countries and organizations have established guidelines and limits for PFAS levels in drinking water and food packaging materials. For instance, the EPA has issued health advisory levels for PFOA and PFOS, two of the most common PFAS chemicals, in drinking water. Similarly, the European Union has set limits for specific PFAS in food contact materials.
Manufacturer Initiatives
Many soda manufacturers have taken steps to reduce the risk of PFAS contamination by implementing strict quality control measures, such as:
- Sourcing water from safe and reliable sources
- Regularly testing water supplies for contaminants, including PFAS
- Using food packaging materials that do not contain PFAS
- Collaborating with suppliers and partners to ensure the use of PFAS-free materials
- Monitoring and addressing any potential PFAS contamination in the environment surrounding their production facilities
These initiatives help ensure that the levels of PFAS, if present, are well below the recommended guidelines, thus minimizing the risk to consumers.
