Project PHASE-OUT: Tackling PFAS with innovative monitoring and removal

Per- and polyfluoroalkyl substances (PFAS), often referred to as “forever chemicals,” are a growing global concern. These substances have been widely used in industrial applications and consumer products due to their stability and resistance to heat, water, and grease. However, this same stability makes them extremely difficult to break down, leading to accumulation in soil, water, and living organisms. As a result, PFAS contamination poses significant risks to ecosystems, food systems, and human health.

The urgency to address PFAS pollution is increasing rapidly. Governments are tightening regulations, and industries are under pressure to reduce emissions and remediate contaminated sites. At the same time, current monitoring and removal methods are often too slow, costly, or limited in effectiveness. For example, analysing a single water sample can take up to two weeks and cost hundreds of euros, making large-scale monitoring challenging.

To tackle these challenges, Wageningen University & Research is leading a major research initiative focused on developing a breakthrough approach to PFAS monitoring and removal. The project aims to create solutions that are not only scientifically robust but also economically viable and applicable in real-world settings

A key component of the project is the development of rapid and cost-effective monitoring methods. Researchers are rethinking existing laboratory tools and adapting them for PFAS detection in innovative ways. One example is the use of ELISA-based techniques, which can analyse large numbers of samples in a fraction of the time required by conventional methods. This could enable the analysis of dozens of samples within minutes, significantly reducing both time and costs.

Improved monitoring will allow industries, water authorities, and policymakers to better understand where PFAS contamination occurs and how it spreads. This knowledge is essential for targeted interventions and effective risk management.

In addition to monitoring, the project focuses on identifying and developing effective PFAS removal technologies. Existing methods often fall short: some are energy-intensive, others only capture certain PFAS compounds, and many are difficult to scale up for practical use. 

WUR researchers are therefore evaluating and combining different technologies to improve performance and scalability. This includes exploring hybrid approaches that integrate detection, concentration, and degradation processes. The goal is to develop systems that can efficiently remove a broad range of PFAS compounds from water streams, including industrial wastewater and surface water.

By focusing on solutions that can be implemented at scale, the project bridges the gap between laboratory research and real-world application.

The expected impact of this project is substantial. Faster monitoring methods will enable earlier detection of contamination, while improved removal technologies will contribute to cleaner water systems and reduced environmental risks. This is particularly relevant for sectors such as water management, industry, and agriculture, where PFAS contamination can have far-reaching consequences.

Ultimately, the project contributes to safer water resources, improved public health, and a more sustainable management of chemical pollutants.

The project is carried out in close collaboration with public and private partners, combining scientific expertise with practical knowledge. Wageningen University & Research contributes its multidisciplinary expertise in environmental technology, analytical chemistry, and process development. Together, the partners work towards innovative and scalable solutions that can be adopted by industry and policymakers.
