The Importance of PFAS Testing in Protecting Public Health
A technical paper by Olympian Water Testing specialists
The history of PFAS use and regulation
Per- and polyfluoroalkyl substances (PFAS) are synthetic chemicals that have been used in things as disparate as nonstick pots, stain-resistant clothes, and fire-fighting foams. These chemicals are incredibly stable and non-degradable, so they will stay in the environment for many decades.
The application of PFAS actually goes back to the 1950s when they were initially invented for industrial and consumer applications. [1] Over the years, PFAS has grown in popularity because of its unusual properties such as water and stain repellent. [2] Because of this, PFAS has found application in everything from food wrappers to clothes and carpets. [3]
PFAS have been the object of worries over the health effects in recent years, however. These are mainly concerns over PFAS being extremely stable and not susceptible to degradation, so that they build up in the environment and in the body. [4] Studies have even reported PFAS-related problems including cancer, liver damage, and immune deficiency. [5]
In light of these worries, regulatory measures have been instituted to tackle PFAS in the environment. In the US, the Environmental Protection Agency (EPA) issued two lifelong health warnings for PFASs: perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS). [6] These advisories set PFOA and PFOS maximum doses as safe for lifetime use.
Aside from the health advisories, the EPA has created a voluntary testing program for PFOA and PFOS in public water systems. [7] The goal of this program is to provide water utilities with information about how many PFAS they have in their system and how to resolve any problems that are discovered.
Along with the federal laws, a lot of states have also put rules and policies in place for PFAS in the environment. They can be highly variable from state to state, where some state standards are higher than those of the EPA, and others take the EPA’s standards as their own. [8]
Overall, PFAS are ubiquitous in numerous products and they have been for years. But some have been concerned about the effects these chemicals could have on the health of humans, so regulation has tried to deal with that. Health warnings and a voluntary testing program have been set by the EPA for PFOA and PFOS, and most states have regulations and guidelines of their own. The people and communities should know these laws, and abide by them for environmental and health protection.

PFAS properties and sources
Per- and polyfluoroalkyl substances (PFAS) are a class of synthetic chemicals that have been used in many industrial and commercial products since the 1950s because of their special chemical structure [1]. These include high thermal and chemical resistance and low surface tension, and they can be used for everything from nonstick cooking pots and clothing to waterproofing and fire fighting foams [2].
But PFAS are also negative for human health and the environment [3]. PFAS are very stable and don’t readily decompose in the environment, which means they accumulate in the environment and in organisms [4]. PFAS have been found in air, water, soil and biota, and in nearly all people examined in the US [1].
There are more than 4,700 PFASs of which there are many possible ways they reach the environment [1]. The major PFAS source comes from discarded products that have been treated with these chemicals as the chemicals can be leached into the soil and water for years [2]. We can also spill PFAS in the environment from the manufacture and use of products containing these chemicals, and by the discharge of wastewater from industrial plants [3].
Humans can absorb PFAS by multiple mechanisms such as through food or water ingestion, air inhalation and dermal absorption [4]. The half-life of PFAS in the human body is not that short and in some studies it can take years for PFAS to be cut in half [2]. With this long half-life and the fact that PFAS are everywhere in nature, humans will be exposed to them for a lifetime [3].
The risk for PFAS in human health is already known [4]. A few studies even correlated PFAS exposure with several adverse health conditions, such as changes in thyroid hormone, immunotoxicity, high cholesterol and cancer [1]. A handful of studies linked PFAS exposure to multiple health effects such as thyroid hormone disturbance [5], immune dysfunction [6], high cholesterol [7], and cancer risk [8]. For instance, in one study, higher PFAS levels in the blood was linked to greater risk of thyroid hormone disruption [5]. Yet another paper showed that PFAS was related to immune system effects in animals, including antibody loss and changes in immune cell numbers [6]. PFAS excess has also been associated with higher cholesterol in humans [7]. And there have also been studies where PFAS was linked to increased risk of certain cancers such as kidney and testicular cancer [8].
Although there is still a vast body of work on PFAS health impacts, it seems likely that exposure to these chemicals can harm humans. The public needs to be able to continue to investigate PFAS’ health impacts, and to act to reduce their exposure in order to safeguard public health. These can range from regulations to limit the amount of PFAS in products, to remediation of contaminated areas and removal of contamination.
Finally, PFAS are a class of synthetic chemicals that have been used in many products because of their chemical nature. But it does seem likely that exposure to PFAS can cause detrimental effects on human health such as the disturbance of thyroid hormones, immune system problems, high cholesterol and a susceptibility to some cancers. We should continue to research the health effects of these chemicals, and try to reduce PFAS exposure for public health purposes.

Health effects of PFAS exposure
PFAS (polyfluoroalkyl substances) are chemicals manufactured by humans that have been around since the 1940s [1]. They are very stable and inert, so they can survive long in the natural world. Those characteristics have rendered PFAS usable for applications as diverse as non-stick pots, water repellent fabrics and fire retardant foam [1]. But PFAS can be damaging to human bodies too, as they have been associated with cancer, liver harm and other conditions [2]. Hence, it’s crucial that PFAS is detectable and quantified in the environment and in samples of humans.
We can perform several tests for the PFAS in the environment and in human samples. Here are some of the most typical ones.
Water or soil samples are a way to test for PFAS in the environment [3]. It’s possible to get water samples from rivers, lakes, wells, and test it for PFAS using any number of methods [3]. Those are liquid chromatography-mass spectrometry (LC-MS), gas chromatography-mass spectrometry (GC-MS), and inductively coupled plasma mass spectra (ICP-MS) [3]. We can even take samples of soil and analyse them in similar ways [3].
Air samples are another source of environmental PFAS testing [4]. You can make air samples by various methods such as high volume samplers, passive samplers, and canisters [4]. These air samples are then analysed by GC-MS or LC-MS [4].
PFAS can be identified in blood, urine and breast milk of humans, too [5]. They can be taken from people and used for analysis using LC-MS and GC-MS [5].
There are also some special techniques to detect and quantify PFAS other than the ones presented above [6]. Those are solid phase extraction (SPE), solid phase microextraction (SPME), and surface enhanced Raman spectroscopy (SERS) [6]. These are all good methods with pros and cons, and they are appropriate for certain samples or applications [6].
Although there are now a range of testing tools available, there are problems determining and quantifying PFAS in the environment and in humans. The issue with that is the low PFAS content that often comes out of these samples [7]. PFAS are also found at very low levels in the environment, and they are not easily detected [7]. There is another problem of additional chemicals which can affect the test results [8].
Let’s summarise, there are several ways to assess PFAS in the environment and in human bodies. They are based on water, soil and air samples, as well as blood, urine and breast milk samples of humans. There are even specific methods like SPE, SPME, and SERS in some cases. But even with these techniques, it’s still hard to accurately detect and quantify PFAS, since the concentrations of these chemicals in samples can be very low and can also be subject to contamination from other chemicals.

PFAS testing methods
Polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that have been in use since the 1940s [1]. They are highly stable and resistant to degradation, which means they can persist in the environment for long periods of time. These properties have made PFAS useful in a wide variety of applications, including non-stick cookware, water-repellent clothing, and firefighting foam [1]. However, PFAS can also be harmful to human health, as they have been linked to cancer, liver damage, and other health problems [2]. As a result, it is important to be able to detect and measure the presence of PFAS in the environment and in human samples.
There are several methods that can be used to test for the presence of PFAS in the environment and in human samples. Some of the most common methods are discussed below.
One method for testing for PFAS in the environment is the use of water or soil samples [3]. Water samples can be collected from sources such as rivers, lakes, and wells, and then analyzed for the presence of PFAS using a variety of techniques [3]. These techniques include liquid chromatography-mass spectrometry (LC-MS), gas chromatography-mass spectrometry (GC-MS), and inductively coupled plasma mass spectrometry (ICP-MS) [3]. Soil samples can also be collected and analyzed using similar techniques [3].
Another method for testing for PFAS in the environment is the use of air samples [4]. Air samples can be collected using a variety of devices, including high-volume samplers, passive samplers, and canisters [4]. The collected air samples can then be analyzed using techniques such as GC-MS and LC-MS [4]. These analytical techniques allow for the detection of specific PFAS compounds at very low concentrations, making them essential for understanding contamination levels. Beyond laboratory analyses, several companies offer pfas testing services available to assist industries and environmental agencies in monitoring and managing PFAS pollution. By utilizing these services, organizations can ensure compliance with regulatory standards and safeguard public health and the environment.
PFAS can also be tested for in human samples, such as blood, urine, and breast milk [5]. These samples can be collected from individuals and analyzed using techniques such as LC-MS and GC-MS [5].
In addition to the methods described above, there are also a number of specialized methods that can be used for the detection and measurement of PFAS [6]. These methods include solid phase extraction (SPE), solid phase microextraction (SPME), and surface-enhanced Raman spectroscopy (SERS) [6]. Each of these methods has its own advantages and disadvantages, and they are best suited to certain types of samples or applications [6].
Despite the availability of a range of testing methods, there are still challenges in accurately detecting and measuring PFAS in the environment and in human samples. One challenge is the low levels of PFAS that are often present in these samples [7]. PFAS are present at very low concentrations in the environment, and detecting them can be difficult [7]. Another challenge is the presence of other chemicals that may interfere with the accuracy of the test results [8].
In conclusion, there are a number of methods that can be used to test for the presence of PFAS in the environment and in human samples. These methods include the analysis of water, soil, and air samples, as well as the analysis of human samples such as blood, urine, and breast milk. Specialized methods such as SPE, SPME, and SERS can also be used in certain situations. Despite the availability of these methods, there are still challenges in accurately detecting and measuring PFAS, due to the low levels of these substances that are often present in samples and the potential for interference from other chemicals.

PFAS regulation and standards
Polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that have been in use since the 1940s [1]. They are highly stable and resistant to degradation, which means they can persist in the environment for long periods of time [1]. These properties have made PFAS useful in a wide variety of applications, including non-stick cookware, water-repellent clothing, and firefighting foam [1]. However, PFAS can also be harmful to human health, as they have been linked to cancer, liver damage, and other health problems [2]. As a result, regulatory frameworks have been put in place to limit the use of PFAS and protect public health.
One of the main regulatory frameworks for PFAS is the United States Environmental Protection Agency’s (EPA) PFAS Action Plan [3]. This plan was released in 2019 and outlines a series of steps that the EPA is taking to address the risks posed by PFAS [3]. One of the key elements of the plan is the establishment of a maximum contaminant level (MCL) for two types of PFAS, perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) [3]. The MCL is a legal limit on the amount of a chemical that is allowed in drinking water [3]. The MCL for PFOS and PFOA is set at 70 parts per trillion (ppt) [3].
In addition to the EPA’s PFAS Action Plan, there are also a number of other regulatory frameworks that address PFAS. For example, the U.S. Occupational Safety and Health Administration (OSHA) has established a permissible exposure limit (PEL) for PFAS in the workplace [4]. The PEL is the maximum amount of a chemical that a worker can be exposed to over an 8-hour workday, 40-hour workweek [4]. The PEL for PFAS is set at 1 microgram per cubic meter (μg/m3) [4].
At the international level, PFAS are regulated by the Stockholm Convention on Persistent Organic Pollutants (POPs) [5]. The Stockholm Convention is a global treaty that aims to eliminate or reduce the release of persistent organic pollutants, including PFAS [5]. Under the convention, PFAS are listed as "chemicals of global concern," which means that they are subject to strict controls on their production, use, and release into the environment [5].
In addition to these regulatory frameworks, there are also a number of voluntary programs that aim to limit the use of PFAS. For example, the FluoroCouncil, a global industry group, has developed a set of principles for the responsible use of PFAS [6]. These principles include the commitment to use PFAS only when necessary, to minimize the release of PFAS into the environment, and to develop alternatives to PFAS when possible [6].
In conclusion, regulatory frameworks and standards have been put in place to limit the use of PFAS and protect public health. These frameworks include the EPA’s PFAS Action Plan, OSHA’s PEL for PFAS in the workplace, and the Stockholm Convention on POPs. In addition to these regulatory frameworks, there are also a number of voluntary programs that aim to limit the use of PFAS.

PFAS remediation and management
PFAS (per- and polyfluoroalkyl substances) are a group of synthetic chemicals that have been widely used since the 1950s in a variety of industrial and consumer products, including non-stick cookware, water-resistant clothing, and firefighting foam [1]. These chemicals are known for their durability and resistance to heat, oil, and water, which makes them useful in a variety of applications. However, their widespread use has also led to widespread contamination of the environment, including the air, water, and soil [1].
PFAS contamination has been linked to a variety of health problems, including cancer, developmental problems, and immune system issues [1]. As such, there has been increasing concern about the need to address PFAS contamination and protect public health.
One approach to addressing PFAS contamination is through remediation, which involves the cleanup of contaminated sites [2]. This can be done through a variety of methods, including physical removal of the contamination, chemical treatment to break down the contaminants, and natural attenuation, which relies on natural processes to break down the contaminants over time [2].
One commonly used method for PFAS remediation is called "pump and treat," which involves pumping contaminated water out of the ground and treating it to remove the PFAS [2]. This method can be effective, but it can also be costly and time-consuming, and it may not be appropriate for all sites [2].
Another approach to PFAS remediation is the use of chemical treatments to break down the contaminants [2]. This can be done through the use of chemicals such as potassium permanganate, which can break down PFAS into less harmful byproducts [2]. However, this method can also be costly and may not be effective at all sites [2].
In addition to remediation efforts, risk management strategies can also be used to address PFAS contamination [3]. This can involve a variety of approaches, including the regulation of PFAS use and the implementation of best management practices to prevent further contamination [3].
For example, the US Environmental Protection Agency (EPA) has established a lifetime health advisory for two specific PFAS chemicals (PFOA and PFOS) and is working to develop regulations for other PFAS chemicals [4]. In addition, the EPA has developed guidance for the management of PFAS-contaminated sites, including best management practices for the prevention of further contamination [4].
There are also a number of state and local initiatives underway to address PFAS contamination [5]. For example, the state of Vermont has established a PFAS Action Plan, which includes a number of strategies for addressing PFAS contamination, including the implementation of best management practices and the development of regulations for PFAS use [5].
Overall, the management and remediation of PFAS contamination is an ongoing challenge that requires a multi-faceted approach [6]. While there are a number of strategies that can be effective in addressing this contamination, the most effective approaches will likely involve a combination of remediation efforts, risk management strategies, and regulatory action [6].

The role of PFAS testing in water quality management
PFAS (per- and polyfluoroalkyl substances)are a group of synthetic chemicals that have been used in a variety of industrial and consumer products, including non-stick cookware, water-resistant clothing, and firefighting foam [1]. These chemicals are known for their durability and resistance to heat, oil, and water, which makes them useful in a variety of applications. However, their widespread use has also led to widespread contamination of the environment, including the air, water, and soil [1].
PFAS contamination has been linked to a variety of health problems, including cancer, developmental problems, and immune system issues [1]. As such, there has been increasing concern about the need to protect the quality of drinking water and other water sources from PFAS contamination.
One way to protect water quality from PFAS contamination is through the use of testing. Testing can be used to assess the presence of PFAS in water sources and to determine the levels of contamination. This information can be used to determine the risk to human health and to inform the development of appropriate management strategies.
There are a variety of methods available for PFAS testing, including both laboratory-based techniques and field-based techniques [2]. Laboratory-based techniques involve the collection of water samples, which are then analyzed in a laboratory using techniques such as liquid chromatography-mass spectrometry (LC-MS) or gas chromatography-mass spectrometry (GC-MS) [2]. These techniques are highly sensitive and can accurately measure low levels of PFAS in water samples.
Field-based techniques, on the other hand, involve the use of portable equipment that can be used to test water sources in the field [2]. These techniques are generally less sensitive than laboratory-based techniques, but they are more practical for testing large numbers of water sources and can provide results more quickly [2].
In addition to testing, there are also a number of strategies that can be used to protect water quality from PFAS contamination. This can include the implementation of best management practices to prevent further contamination, such as the proper storage and handling of PFAS-containing products [3]. It can also involve the treatment of water to remove or reduce PFAS contamination, such as through the use of activated carbon filtration or reverse osmosis [3].
Overall, the use of PFAS testing is an important tool in the management of water quality and the protection of public health. By accurately assessing the levels of PFAS contamination in water sources, it is possible to determine the appropriate management strategies and to ensure that drinking water and other water sources are safe for human consumption.

The impact of PFAS on vulnerable populations
PFAS (per- and polyfluoroalkyl substances) are a group of synthetic chemicals that have been used in a variety of industrial and consumer products, including non-stick cookware, water-resistant clothing, and firefighting foam [1]. These chemicals are known for their durability and resistance to heat, oil, and water, which makes them useful in a variety of applications. However, their widespread use has also led to widespread contamination of the environment, including the air, water, and soil [1].
PFAS contamination has been linked to a variety of health problems, including cancer, developmental problems, and immune system issues [1]. While the general population is at risk of exposure to PFAS, certain populations may be more vulnerable to the effects of PFAS exposure due to their unique characteristics or circumstances.
One population that may be particularly vulnerable to the effects of PFAS exposure is children. Children may be more susceptible to the effects of PFAS exposure due to their developing bodies and their higher intake of food, water, and air relative to their body size [2]. In addition, certain PFAS chemicals have been shown to disrupt the endocrine system, which plays a critical role in the development of the body [2].
Pregnant women are also a vulnerable population when it comes to PFAS exposure. Pregnant women can be exposed to PFAS through their diet, as well as through their drinking water [3]. This can result in the transfer of PFAS to the developing fetus, which can lead to adverse health effects [3]. Pregnant women who are exposed to high levels of PFAS may be at increased risk of preterm delivery and low birth weight [3].
In addition to children and pregnant women, other vulnerable populations may include those with compromised immune systems, such as individuals with HIV or cancer, as well as older adults, who may be more sensitive to the effects of toxic chemicals [4].
Overall, it is important to recognize that certain populations may be more vulnerable to the effects of PFAS exposure and to take steps to protect these populations from exposure. This can involve a variety of strategies, such as the testing of drinking water to assess the levels of PFAS contamination and the implementation of best management practices to prevent further contamination.

The use of PFAS alternatives
PFAS (per- and polyfluoroalkyl substances) are a group of synthetic chemicals that have been used in a variety of industrial and consumer products, including non-stick cookware, water-resistant clothing, and firefighting foam [1]. These chemicals are known for their durability and resistance to heat, oil, and water, which makes them useful in a variety of applications. However, their widespread use has also led to widespread contamination of the environment, including the air, water, and soil [1].
PFAS contamination has been linked to a variety of health problems, including cancer, developmental problems, and immune system issues [1]. As such, there has been increasing concern about the need to reduce the use of PFAS and to find safer alternatives.
One approach to reducing the use of PFAS is the development and use of alternatives. There are a number of alternatives to PFAS that are being developed and used, including both chemical and non-chemical alternatives.
Chemical alternatives to PFAS include a variety of fluorinated and non-fluorinated chemicals that can provide similar performance characteristics to PFAS [2]. These alternatives may have lower toxicity and be less persistent in the environment, which could reduce the potential for contamination and the associated health risks [2]. However, it is important to carefully assess the potential risks and benefits of these alternatives, as some may still pose environmental and health concerns [2].
Non-chemical alternatives to PFAS include a variety of materials that do not contain fluorinated compounds, such as plant-based oils and waxes, cellulose-based materials, and biodegradable polymers [3]. These alternatives may be less persistent in the environment and may pose fewer health risks compared to PFAS, but they may also have different performance characteristics that may limit their use in certain applications [3].
Overall, the use of alternatives to PFAS is an important strategy for reducing the use of these chemicals and protecting public health. While there are potential benefits and drawbacks to different alternatives, it is important to carefully assess the risks and benefits of each option to determine the most appropriate solution.

The future of PFAS testing and regulation
PFAS (per- and polyfluoroalkyl substances) are a group of synthetic chemicals that have been used in a variety of industrial and consumer products, including non-stick cookware, water-resistant clothing, and firefighting foam [1]. These chemicals are known for their durability and resistance to heat, oil, and water, which makes them useful in a variety of applications. However, their widespread use has also led to widespread contamination of the environment, including the air, water, and soil [1].
PFAS contamination has been linked to a variety of health problems, including cancer, developmental problems, and immune system issues [1]. As such, there has been increasing concern about the need to test for and regulate PFAS to protect public health.
In the coming years, it is likely that PFAS testing and regulation will continue to evolve in response to growing concerns about the potential health risks associated with these chemicals. One key area of focus is likely to be the development of more sensitive and specific methods for detecting PFAS in the environment and in human samples [2]. This will enable more accurate assessments of exposure and will help to inform regulatory decisions about the use and management of these chemicals.
In addition to advances in testing, it is also likely that there will be further efforts to regulate the use of PFAS. This could involve a variety of approaches, such as the development of limits on the levels of PFAS that are allowed in consumer products or the establishment of regulations to control the use of PFAS in certain industries [3].
Overall, the future of PFAS testing and regulation is likely to involve a combination of advances in testing technologies, regulatory action, and efforts to reduce the use of these chemicals. These efforts will be critical for protecting public health and ensuring that the risks associated with PFAS are properly managed.
