But even with all this effort there still remain significant hurdles when it comes down how best regulate use manage risks associated without causing undue harm or unnecessary panic amongst populations already concerned over their wellbeing due environmental factors beyond control thus requiring more robust legal frameworks capable ensuring long term sustainability both ecological human societies alike moving forward together harmoniously side by side into future generations yet come
Introduction
Recently, there has been a significant amount of discussion surrounding per- and polyfluoroalkyl substances, more commonly called PFAS or ‘forever chemicals’. These are synthetic chemicals present in various common products like nonstick cookware, waterproof garments, and food containers. They are called forever chemicals because they linger in the environment and human bodies, sparking concerns about their potential impact on health.
Due to the difficulty of breaking down these chemicals, they can enter the air, water, and soil, leading to human exposure. Mounting evidence suggests that this exposure, even at very small quantities, could result in severe health conditions such as cancer, developmental issues in children, and decreased fertility rates.
Both the United States and the United Kingdom have taken steps to address PFAS contamination, with regulatory bodies like the Environmental Protection Agency (EPA) in the U.S. implementing strategies to reduce PFAS levels. Similarly, authorities in the U.K. are ensuring the cleanliness of drinking water by combatting these pollutants, though their regulatory regime so far has not been binding.
Understanding PFAS and Its Impact on Public Health
Concerns regarding the impact of PFAS on health are escalating. These harmful substances have been associated with severe health issues such as cancer, developmental problems in children, and fertility challenges. Studies indicate that exposure to PFAS may elevate cholesterol levels, harm the liver and thyroid, and disrupt immune function.
A significant route of human exposure to these chemicals is through contaminated drinking water. This occurs when industrial sites release them into water sources, through the use of firefighting foam, and in products containing PFAS. Once these substances enter our water supplies, individuals can ingest them by consuming tainted water or food that has come into contact with it.
Vulnerable groups like pregnant women and children are at a heightened risk due to the health effects of PFAS exposure. The World Health Organization has emphasized that any level of exposure to PFAS is not considered safe.
What Are PFAS?
PFAS that have been in existence since the 1940s. They are utilized across various sectors due to their ability to withstand heat, water, and oil without deterioration. PFAS became key components in both consumer goods, including famously non-stick pans, and industrial applications.
Essentially, PFAS are composed of tightly bonded carbon and fluorine atoms and are understood as a kind of plastic. Among the numerous PFAS varieties, prominent names include PFOA and PFOS, which have played crucial roles in creating products like non-stick cookware and stain-resistant clothing.
Health Risks Associated with PFAS Exposure
Known health risks include:
An increased risk of certain cancers such as kidney and testicular cancer.
Disruption to hormone levels and impact the functioning of the endocrine system.
Liver damage
Altered cholesterol levels, which may contribute to heart disease.
Pregnant women and children face even greater dangers, as these chemicals can impede growth and overall development. Furthermore, pregnant women pass on PFAS to their children. The World Health Organization has emphasized that no level of PFAS exposure is considered safe.
Current PFAS Regulations in the United States
In the United States, the Environmental Protection Agency (EPA) has led the establishment of water regulations to safeguard against PFAS in our drinking water supply. In April 2024, the EPA introduced the inaugural nationwide, legally binding drinking water regulation aimed at safeguarding communities from detrimental PFAS exposure. This landmark regulation is expected to cut PFAS exposure for roughly 100 million individuals, avert thousands of fatalities, and lessen tens of thousands of severe health conditions. Simultaneously, the EPA unveiled an additional $1 billion in funding to assist states and territories with PFAS testing and treatment in public water systems and to aid private well owners in addressing PFAS pollution.

This regulation establishes specific limits for perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) in drinking water, as these chemicals are commonly found in everyday products. The EPA has set a maximum combined concentration of 70 parts per trillion for PFOA and PFOS based on scientific research indicating potential health risks associated with PFAS exposure. Water systems are required to monitor their water quality regularly and report to authorities to ensure compliance with the new standards. Additionally, the EPA offers guidance on its website to support water systems in meeting the requirements for maintaining clean drinking water free from contaminants.
State-Level Initiatives and Regulations
In addition to federal government actions, states throughout the United States are taking measures to address PFAS contamination in their water systems. They are implementing their own regulations to safeguard drinking water quality and protect public health from the adverse effects of PFAS. Leading states such as Michigan, New Jersey, and California are enforcing stringent rules on PFAS, including setting limits on permissible levels in drinking water and mandating regular monitoring and reporting by water management authorities. Through testing groundwater, many states can identify areas with elevated PFAS levels and implement measures to preserve the cleanliness of drinking water sources. These state-level initiatives are crucial as each state has unique requirements for ensuring water safety. By undertaking these efforts, states are ensuring widespread access to clean drinking water while addressing contamination issues effectively.
The UK’s Approach to PFAS in Drinking Water
In the UK, proposals have been put forth to address PFAS in drinking water, focusing on ensuring water safety and minimizing health risks associated with PFAS. These proposals involve establishing secure online platforms for accessing information on PFAS contamination. Regular monitoring and testing of water sources are part of the plan to detect any presence of PFAS. There is also a push to establish guidelines on acceptable PFAS levels in water; however, national regulators have yet to issue any enforceable regulations for drinking water providers. Instead, the Drinking Water Inspectorate has issued recommendations for a 'wholesomeness' guideline value of 100 ppt, though other groups including Royal Society of Chemistry have pushed for stricter limits.
Although not mandatory regulations, adhering to this guidance is crucial for those responsible for water management and purification. By following these recommendations, the aim is to safeguard public health by maintaining the purity of drinking water.
