A landmark study has been recently published by the European Commission, revealing that pollution from per- and polyfluoroalkyl substances (PFAS), commonly known as “forever chemicals,” could impose costs of approximately €440 billion on the European Union by 2050 if current contamination continues unchecked, placing heavy burdens on health systems, environmental restoration efforts and public budgets.

The report, titled “The cost of PFAS pollution for our society”, provides the first comprehensive EU estimate of the economic impacts of PFAS contamination. It calculated that maintaining the status quo would lead to massive expenditure on treating polluted water and soil, alongside addressing the long-term health consequences of exposure to substances linked to cancer, hormone disruption and immune disorders. Early action to halt PFAS emissions by 2040 could save around €110 billion relative to continuing current practice.

These findings have come at a crucial moment for Europe’s environmental governance, reinforcing calls by scientists, civil society and policymakers for stricter regulation and robust implementation of the “polluter-pays principle” to ensure industry contributes fully to remediation costs.

Against this backdrop, ARAGORN project is making important strides to help Europe tackle soil pollution, including contaminants such as PFAS, metals, organo-chlorines and petroleum-derived residues. ARAGORN provides decision-making tools, mapping and monitoring solutions that empower land managers to prioritise effective, resilient and sustainable remediation strategies.

Soils across Europe are under unprecedented stress: more than 60 % are considered unhealthy, making coordinated action imperative to secure food production, clean water and ecosystem health. ARAGORN works with public and private stakeholders to move beyond “regrettable remediation” towards restorative approaches that protect ecological function and community wellbeing.

As the latest EU study on PFAS costs makes clear, the economic and social toll of environmental pollution is vast, and projects like ARAGORN have a very relevant role to developing the knowledge, tools and collaborative networks needed to remediate contaminated land effectively and equitably across Europe.

With PFAS contamination now quantified at EU level and the financial stakes rising into the hundreds of billions, coordinated research, innovation and policy implementation are vital to protecting human health, restoring natural environments and strengthening Europe’s resilience to legacy pollution.

ARAGORN was actively represented at the Soil Pollution and Remediation Cluster Meeting held recently in Aarhus, Denmark, where experts, researchers, and EU-funded initiatives gathered to exchange knowledge on some of the most pressing challenges related to soil pollution, land contamination, and innovative remediation strategies.

During the meeting, ARAGORN’s coordinator and several project partners joined fellow projects in a series of discussions focused on emerging contaminants, risk assessment approaches, and the need for integrated solutions to restore soil health across Europe. The event provided a valuable platform for sharing experiences, aligning methodologies, and strengthening collaboration within the EU’s environmental research community.

A key contribution from ARAGORN was the presentation of four newly developed factsheets, each dedicated to one of the major groups of contaminants addressed in the project: Metals, PETCO (Petroleum-derived contaminants), OCBs (Organochlorine-based compounds),PFAS (Per- and polyfluoroalkyl substances).

These factsheets, designed to offer clear and accessible insights into contamination pathways, environmental risks, and relevant remediation approaches, were distributed on-site and well received by participants, as they generated interest and stimulated conversations on current scientific knowledge and ongoing research gaps. The factsheets will soon be publicly available on the ARAGORN Zenodo community and on the project’s official website, stay tuned!

ARAGORN and other EU Mission soil projects are back in the spotlight, working together to safeguard Europe’s soils. Their contribution has recently been recognised in the EU Soil Observatory newsletter, which features fresh insights from a new Joint Research Centre (JRC) report on soil pollution data.

The JRC report emphasises that harmonised soil data is crucial for policy-making, decision support, and sustainable land management. Within this context, ARAGORN plays a pivotal role by providing a structured data and metadata architecture aligned with European soil policies.

Through its GIS dashboard, ARAGORN integrates multiple datasets, including risk and socio-economic assessments, inventories of potential and known contaminated sites, chemical fingerprints of common polluting activities (such as PFAS, PETCO, OCB, and metals), and soil characteristics including eDNA data from remediated sites. The dashboard also incorporates decision tree logic to guide remediation and restoration efforts, indicators for human and ecotoxicological risk, and parameters for cost-benefit analyses of soil management strategies.

By combining these datasets, ARAGORN goes beyond pure research: it provides a tangible toolkit to analyse harmonised data, enabling informed decision-making. Projects like this are essential for the protection and remediation of European soils—the invaluable humus of life.

Far from pausing over the summer, ARAGORN pressed ahead, achieving measurable progress in restoring Europe’s polluted soils. On July 30, an engaging public workshop took place at the Pezinok site, where the local geological heritage intersects with pressing environmental challenges.

An information panel has now been permanently installed at the site to inform visitors about the complex history of mining and mineralization in the area and the ARAGORN initiative’s role in soil remediation.

• Presentation by ARAGORN: Project representatives delivered an accessible overview of ARAGORN’s goals—helping land managers across Europe move from “regrettable” to “restorative” remediation through innovative mapping, monitoring tools, and nature-based solutions.
• Local Engagement: The workshop drew key local stakeholders, including the site owner NGO Barbora and the Mayor of Pezinok, underscoring the close cooperation between the project and community leaders.
• Public Awareness: The focus was to gain insights into how ARAGORN’s frameworks align with EU Soil Strategy goals, and how Pezinok fits into the broader European context of soil restoration.

Pezinok site

The Pezinok region is a classic example of the Malé Karpaty crystalline complex—composed of metabasalts, metasediments, and granitoids—within the Bratislava and Modra massifs. This area has a long mining history. Its rocks contain a variety of valuable minerals, including antimony, arsenic, gold, and other metals. While these resources were important in the past, mining left behind pollution that still affects the soil and environment today.

Because of this legacy, Pezinok is a key site for the ARAGORN project, which is testing new ways to study and restore land damaged by mining.

• Historical mining legacy: Pezinok is emblematic of mining-impacted landscapes in Europe, where generations of extraction left soils and tailings contaminated with metals like antimony and arsenic.
• Test-bed suitability: Its geological diversity and documented contamination make it an ideal testing ground for ARAGORN’s tools—risk assessment, community-engaged decision-making, nature-based solutions, and remediation planning.
• Community integration: The installation of the information panel and the active involvement of local stakeholders demonstrate ARAGORN’s emphasis on local empowerment and long-term stewardship.

ARAGORN will continue collaboration with local partners to:

• Monitor the Pezinok site with its mapping and decision-support tools.
• Explore and test tailored remediation solutions.
• Extend public outreach and educational initiatives around soil health and restoration.

ARAGORN project was featured in an interesting video aired on national television in Slovakia, focused on Pezinok – a contaminated site that is part of the project research sites. Hana Horváthová and Veronika Špirová, who are actively working within the ARAGORN project, were interviewed in ordet to address long-standing environmental issues related to mining activity in Pezinok.

At the end of the 20th century, various ores and metal-beraing rocks, such as antimony and arsenopyrite were mined in Pezinok, particularly around the Budúcnosť adit, which ceased operations in 1993. However, significant environmental pollution remains due to mine waste and contaminated water still leaking from the adit.

Researchers from the Faculty of Natural Sciences at Comenius University in Bratislava proposed an innovative solution using industrial waste – specifically iron shavings and iron-rich sludge- to help reduce the spread of toxic substances. They created three test plots: soil mixed with sludge, soil mixed with iron shavings, and untreated soil (control plot).

These iron-based materials, which naturally bind heavy metals, are being tested to observe their impact on contaminated soil. Early results suggest that the plots treated with waste materials release less arsenic and antimony into soil water compared to the control. This indicates the potential of these materials to stabilize pollutants and limit their spread into surrounding soil, groundwater, and plants.

The researchers emphasize that both materials are industrial by-products, and this approach offers a way to repurpose waste while tackling environmental contamination. If long-term results confirm their effectiveness, this strategy could be implemented in real-world remediation efforts.

This brings a lot optimism about scaling the approach in the future, marking an important step in sustainable remediation practices.

From May 25-28, 2025, ARAGORN consortium gathered for its third General Assembly in the historic Banat region of southwestern Romania, convening at Coronini and the nearby Moldova Nouă site.

Consortium updates and collaborative workshops
The meeting opened at a riverside venue in Coronini with a welcome from ARAGORN coordinator, Xenia Trier (UCPH) and WP leads, who provided scientific talks on contaminant analysis and bioavailability. Partners from WP1 -WP4 delivered concise progress reports on mapping strategies, remediation techniques, resilience modeling, and stakeholder engagement guidelines . During plenary sessions and side-group meetings, many partners refined the project’s decision tree and sampling plans, ensuring that methods remain fit-for-purpose in diverse European contexts.

On Day 1, a side meeting organized by UCPH’s monitoring team explored the integration of fit-for-purpose quantitative methods under WP2. Besides, participants engaged in a role-playing game devised by ICONS, stepping into the shoes of farmers, regulators, and industry representatives debating soil contamination and remediation priorities. This exercise fostered empathy and illuminated real-world stakeholder dilemmas, reinforcing ARAGORN’s co-creative ethos.

Site visits: old copper mine and “Attila’s island”
On Day 2, delegates traveled to the Moldova Nouă test site- a former copper mine whose spoil heaps present a complex mix of metal contamination. Partners and experts had the occasion to visit a specific site for soil contamination and discuss phytomanagement and microbial remediation approaches in small breakout groups .

In the afternoon, the consortium joined local stakeholders for a field excursion to Ostrov Moldova Veche, often called “Attila’s Island.” Here, a herd of semi-feral horses grazes among ruins said to conceal the legendary Tomb of Attila the Hun. This vivid legend added a touch of myth to the scientific mission, inspiring reflections on how cultural heritage and community memory intersect with ARAGORN’s environmental goals.

Reflections, side meetings, and next steps
Back at Coronini, Day 3 featured an expert panel on risk assessment and remediation frameworks, followed by the General Assembly itself, where each partner delivered a concise update on their work force. Plenary discussions emphasized synergies between mapping, monitoring, and stakeholder engagement, setting coordinated milestones for the next six months.

Throughout the three-day gathering, side meetings focused contaminant prioritization, quantitative methods, and resilience modeling, ensuring seamless handovers as personnel transitions occur. Cooperative dialogues also addressed plans for upcoming sampling campaigns at Turda and other hotspots, with a view to refining ARAGORN’s decision tree before its release in early 2026.

Celebrating science and local culture
Consortium members had the chance to share a traditional Romanian dinner at Tarabostes ranch. Theis convivial gathering fostered the collaborative spirit that underlies ARAGORN’s approach. Traditional Romanian dances were the perfect ending to this fruitful meeting!

ARAGORN was proudly presented at the SETAC Europe Annual Meeting held in Vienna. A diverse team of researchers shared their latest interdisciplinary work aimed at addressing the urgent challenge of soil contamination and restoration across Europe.

Throughout April, a collaborative social media campaign led by ARAGORN together with two other EU projects, GUARDIANS and MRV4SOC, shed light on key concepts shaping the field of soil contamination research. Centered on a shared Glossary of soil contamination, the campaign aimed to make technical language more accessible to the public, and to increase interest towards relevant topics for soil contamination.

Each week, a visually engaging social media card introduced and explained a term central to the ongoing efforts to understand, prevent, and remediate soil pollution. The featured terms included:

• Resilience

• Zero Pollution

• Forever Chemicals

• Contaminated Site

• Soil Remediation

The campaign successfully reached and engaged a broad audience on social media, creating a space for knowledge-sharing and public awareness. It also highlighted the importance of building a common vocabulary to ensure effective communication across science, policy, and society in addressing the urgent challenge of soil health.

In response to rising concerns over pollution from toxic “forever chemicals”, an expert team coordinated by ARAGORN and with inputs from ZeroPM has delivered recommendations to the European Commission on how to monitor PFAS (per- and polyfluoroalkyl substances) in European soils.

PFAS are a group of over 12,000 synthetic substances used in industrial and consumer products, many of which persist in the environment and can pose health risks. With their increasing presence in soil, water, and food, the need for effective monitoring has become urgent.

The proposed approach supports the EU’s upcoming Soil Monitoring and Resilience Directive (SMRD), combining targeted PFAS analysis with broader screening for unidentified contamination. The initial rollout is expected to tie into the 2026 LUCAS soil survey and will focus on using existing lab methods, making it feasible within a tight timeframe and budget. The strategy recommends testing for 43 key PFAS compounds using a combination of LC-MS/MS methods, and assessing total PFAS levels with cost-effective techniques such as EOF (extractable organofluorine) or TOP (total oxidizable precursor) assay. This comprehensive monitoring can be achieved within an estimated €500–€600 per sample.

The 43 PFAS were selected to reflect common PFAS sub-groups with a strong tendency to bind to soils, helping ensure the monitoring captures the most indicative substances for identifying pollution sources. Meanwhile, the highly mobile and persistent trifluoroacetic acid (TFA) was recommended for analysis in water rather than soil, as water sampling of TFA is less affected by weather-related variations.

The experts also advise aligning soil monitoring with water, food, and air regulations to ensure consistency and reduce regulatory overlap. Aligning regulations, they note, will also help reduce the complexity of implementation for farmers, waterworks, and environmental authorities.

By identifying hotspots and tracking trends, the new system aims to prevent pollution before it spreads and hold polluters accountable — a crucial step in protecting Europe’s soils, water resources, and public health.
