Key Findings
- 01PFOA and PFOS are the most detected PFAS in the environment and are associated with plastic pollution and endocrine dysfunction.
- 02Contamination rates of PFOA and PFOS have shown significant increases.
- 03Developed countries have stringent guidelines, but developing nations lack adequate regulations and mechanisms to address PFAS.
- 04Advancements in PFAS removal technologies are needed for improved efficacy and feasibility.
- 05Comprehensive approaches for exposure assessment and risk characterization are imperative.
Application
Design takeaway
Prioritize research and development into advanced, cost-effective PFAS removal systems and advocate for globally harmonized water quality standards.
How to apply
When designing water treatment systems, investigate and integrate emerging filtration, adsorption, or degradation technologies specifically proven effective against PFAS. Consider the lifecycle impact of chosen materials and processes.
Project actions
- 01When researching a problem, look for chemicals or materials that are known to persist in the environment.
- 02Consider how your design might contribute to or solve issues of widespread contamination.
- 03Investigate existing regulations and identify areas where they are lacking or inconsistent.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Comprehensive review of historical data on PFAS contamination.
- +Analysis of global disparities in regulatory approaches.
- +Identification of key challenges and future needs in PFAS management.
Limitations
The effectiveness of proposed solutions may be difficult to test comprehensively within the scope of a design project. Real-world implementation challenges, such as cost and infrastructure, are significant.
Reliability & validity
The reliability of the findings depends on the quality and comprehensiveness of the reviewed literature. Validity is strengthened by the systematic review approach and the NABC analysis, which provides a structured framework for evaluation.
Think critically
Given the persistence of PFAS, is it more effective to focus on removal technologies or on preventing their introduction into the environment in the first place?
Design Principles
"Design for Persistence: Develop solutions that account for the long-term environmental persistence of contaminants and aim for their complete removal or elimination."
As designers and engineers, understanding the persistent nature of contaminants like PFAS is crucial for developing sustainable water treatment solutions. This insight highlights the need for innovative approaches that go beyond current capabilities and emphasizes the importance of considering global disparities in regulatory frameworks when designing for widespread impact.
What This Means for Your Design
Chemicals called 'forever chemicals' are getting into our drinking water and are hard to get rid of. We need better ways to clean the water and for countries to agree on rules to stop this pollution.
How to use in your project
- 1.Use this research to justify the need for your design solution, especially if it addresses environmental contamination or public health.
- 2.Cite the findings on PFAS persistence and the lack of global regulations to highlight the significance of your design project.

Paragraph starter
Research indicates a significant and growing problem with per- and polyfluoroalkyl substances (PFAS), such as PFOA and PFOS, contaminating drinking water sources globally. These 'forever chemicals' are persistent and pose health risks, yet effective and widely adopted removal technologies are lacking, particularly in developing nations. This underscores the critical need for innovative design solutions in water treatment and the development of robust, internationally consistent regulatory frameworks to safeguard public health and water security.
