Updated 27 October 2026
Europe’s soil assessment framework has changed, but environmental professionals should not expect a single new table of EU-wide Generic Assessment Criteria (GAC).
The EU Soil Monitoring Law establishes a common approach to assessing soil health and managing contaminated sites. It combines shared monitoring requirements with national decisions on targets, triggers and unacceptable risks. The practical task is to distinguish these different criteria before applying them to project data. Council of the EU
Key takeaways
- There is no new universal EU GAC table. The law does not prescribe one set of soil contaminant concentrations for every site.
- The major legal update arrived in 2025. The Soil Monitoring Law entered into force on 16 December 2025.
- National implementation is next. Member States must transpose the directive by 17 December 2028.
- The EEA framework is scientific guidance. Its January 2023 report supports soil-health assessment rather than providing legally binding cleanup limits. EU directive, European Commission, EEA report
What are the latest levels?
The answer depends on what you are assessing: contamination risks at a particular site, or the wider health of soils.
| Framework or criterion | Latest position | Relevant date |
|---|---|---|
| EU-wide contaminated-land GAC | No universal numerical concentration table introduced by the Soil Monitoring Law | Directive dated 12 November 2025 |
| Sustainable soil-health targets | Non-binding targets; Annex I combines EU criteria with criteria established nationally | 2025 directive |
| Operational trigger values | Set by Member States to identify degradation requiring support for soil health and resilience | National transposition due 17 December 2028 |
| EEA indicators and thresholds | Scientific indicators and critical limits for assessing soil functions | Published 18 January 2023 |

For project screening, select criteria accepted in the relevant jurisdiction and check their assumptions. The Environment Agency’s guidance explains that GAC depend on factors such as land use, contaminant form, exposure pathways and the people or environments being protected. A screening exceedance calls for evaluation; it does not automatically establish that remediation is necessary. Environment Agency: land contamination risk assessment
What changed in the EU framework?
A common approach to monitoring
The law brings physical, chemical and biological soil conditions into a shared monitoring framework. It also addresses soil sealing and removal, helping countries produce more comparable information about soil degradation and contaminated sites. Council adoption summary
Its scope extends beyond contamination to erosion, declining organic matter, salinisation, compaction and biodiversity loss. This makes it relevant to agricultural, urban and forest soils as well as industrial land. European Commission overview
Greater attention to PFAS and pesticides
Member States must select contaminants for additional monitoring, including PFAS, pesticides and their metabolites, based on risk. The Commission must establish an indicative contaminant list by 17 June 2027. These monitoring provisions do not introduce a universal EU PFAS soil screening concentration. Directive, Articles 7–8
National responsibility for contaminated-site risks
Member States determine unacceptable risk and establish site-specific assessment methods, taking account of current and planned land use. National implementation therefore remains essential to interpreting the law for individual projects. Directive, Article 16
When was the law adopted?
The Council approved the law on 29 September 2025, followed by Parliament’s final approval on 23 October 2025. The directive entered into force on 16 December 2025. European Commission timeline
The national transposition deadline is 17 December 2028, as specified in Article 26 of the final legal text. Directive, Article 26
What does the EEA’s 2023 framework provide?
The EEA published Soil monitoring in Europe – Indicators and thresholds for soil health assessments on 18 January 2023. Its designation, EEA Report 08/2022, can cause confusion about the publication year. EEA publication record
The report brings together indicators covering organic carbon, nutrients, acidification, pollution, biodiversity, erosion, compaction and sealing. Its thresholds identify conditions where soil functions—such as water purification and food production—may be harmed.
These are scientific reference points for protection and restoration. They should not be presented as an EU-wide schedule of statutory contamination limits. EEA explanation of the framework
What should environmental professionals do now?
For each assessment:
- Confirm the applicable jurisdiction and criteria.
- Check suitability: land use, medium, units, contaminant definition and exposure assumptions.
- Record the source and version of each guideline used.
- Explain exceedances in context, including whether further assessment is required.
These steps help keep automated comparisons defensible and reports clear about what a result means. Environment Agency guidance
Keeping standards current in ESdat
ESdat has recently compiled updated standards across North America, Europe and Australia.
These updates allow users to seamlessly apply current guideline values, automate compliance monitoring, and incorporate the latest standards into reporting and decision-making workflows in ESdat.
Its standards library supports comparisons with laboratory and field results, guideline-exceedance alerts and user-defined site limits. Selecting the appropriate standard remains part of the assessment process. Explore ESdat environmental standards
Glossary
- GAC — Generic Assessment Criteria: Screening values based on standard assumptions about exposure and site conditions.
- Soil descriptor: A measurable property used to assess soil condition.
- Sustainable target value: A non-binding reference for healthy soil condition.
- Operational trigger value: A national threshold signalling a need for soil-health support.
- PFAS: Per- and polyfluoroalkyl substances, a large group of synthetic chemicals.
- Transposition: Bringing an EU directive’s requirements into national law.
Frequently asked questions
Has the EU replaced national soil screening standards?
No. The law establishes a common framework while retaining national decisions on contamination criteria and unacceptable risk. Check the rules applicable to the project location. EU directive
Does exceeding a GAC automatically require cleanup?
No. Review the result against the assessment’s assumptions and objectives to determine whether the risk is acceptable or further assessment is needed. Environment Agency guidance
Are the EEA thresholds legally binding?
The EEA report provides scientific guidance. Any legal requirement must be established from the applicable legislation. EEA framework
Can the same screening value be used across European projects?
Only where it is suitable for the site and accepted in the relevant jurisdiction. A common reporting system does not remove the need to justify the selected criteria. Environment Agency guidance
