What’s Required
1. Prevent Chemical, Biological and Physical Soil Degradation
Landowners, developers, agricultural operators, construction companies and other responsible parties must avoid activities that could impair soil fertility or create risks to people, animals, plants or ecosystems.
The framework covers:
Chemical contamination caused by pollutants, fertilisers, pesticides, industrial substances, waste or contaminated materials.
Physical degradation, including compaction, erosion, structural damage and the removal or disturbance of fertile topsoil.
Biological impacts associated with pathogenic, genetically modified or non-native organisms.
Preventive measures must reflect the type of activity, the soil's sensitivity, and the likelihood of long-term damage. The VBBo protects soil against chemical, physical and biological pressures and operates alongside the Swiss Environmental Protection Act and related waste, contaminated-sites and land-use rules.
2. Protect Long-Term Soil Fertility
Activities affecting soil must be planned and carried out so that the soil can continue performing its ecological and productive functions over the long term.
This includes preserving:
Soil structure and porosity.
Water retention and drainage capacity.
Biological activity.
Plant-growth capacity.
Agricultural productivity.
The soil’s ability to filter, buffer and transform pollutants.
Where construction, excavation, agriculture or industrial activities may damage these functions, appropriate protective methods must be used.
3. Prevent Soil Compaction and Erosion
Operators must take reasonable measures to prevent soil compaction and erosion, particularly during construction, civil engineering, forestry and agricultural operations.
Typical measures include:
Avoiding work on water-saturated or highly vulnerable soil.
Restricting the use of heavy machinery.
Establishing designated vehicle routes.
Separating topsoil and subsoil during excavation.
Limiting the duration and extent of exposed soil.
Stabilising slopes and disturbed areas.
Restoring soil layers correctly after construction.
Monitoring erosion-prone agricultural land.
The ordinance specifically addresses artificial changes to soil structure and requires measures to avoid compaction and erosion.
4. Assess Soil Contamination Against Regulatory Values
Federal and cantonal authorities assess soil contamination using three principal categories of values:
Guide values: Indicate the level below which long-term soil fertility is generally considered protected.
Trigger values: Indicate that contamination may pose a concrete risk under a particular land use and requires further investigation.
Remediation values: Indicate that the soil poses an unacceptable risk and that its use must be restricted or remediation measures implemented.
The applicable values depend on the contaminant and the way the land is used, such as agriculture, horticulture, residential use, playgrounds or livestock production. Where no national value exists, cantonal authorities may establish a case-specific value with the agreement of the Federal Office for the Environment.
5. Monitor Areas with Known or Suspected Soil Impacts
Cantonal authorities must monitor areas where soil contamination is known or reasonably expected to threaten soil fertility.
Monitoring may include:
Soil sampling and laboratory analysis.
Mapping the location and extent of contamination.
Reviewing historic industrial or agricultural land use.
Assessing pollutant concentrations and exposure pathways.
Examining risks to people, animals, plants and food production.
Monitoring physical degradation such as compaction or erosion.
Cantons must communicate relevant monitoring results to the Federal Office for the Environment and make results available publicly. The federal government and the cantons also use the National Soil Monitoring Network, NABO, to identify long-term changes and emerging soil risks.
6. Manage Excavated and Removed Soil Correctly
Excavated topsoil and subsoil must be examined, separated, stored, transported, reused or disposed of in a manner that does not spread contamination or damage fertile soil.
Projects may need to:
Characterise soil before excavation.
Distinguish uncontaminated, slightly contaminated and polluted soil.
Keep topsoil separate from subsoil and other excavation materials.
Prevent mixing clean soil with contaminated material.
Use suitable storage conditions.
document the origin, quality, destination and reuse of excavated soil.
Send materially contaminated soil to an authorised treatment or disposal facility.
Ensure reused soil is suitable for the receiving site and intended land use.
Additional requirements may arise under the Waste Ordinance, the Contaminated Sites Ordinance and cantonal construction rules.
7. Implement Protective Measures During Construction
Construction and infrastructure projects affecting significant areas of soil may be required to prepare a soil-protection plan or appoint a qualified soil-protection specialist.
Protective measures can include:
Pre-construction soil surveys.
Mapping of sensitive or contaminated areas.
Machinery and access restrictions.
Weather-dependent working conditions.
Soil handling and storage procedures.
Erosion and sediment controls.
Post-construction restoration.
Follow-up inspections and monitoring.
Compliance conditions may be incorporated into planning permission, environmental approvals or construction permits.
8. Comply with Cantonal Restrictions and Remediation Orders
When guide, trigger or remediation values are exceeded, the competent canton may order measures proportionate to the identified risk.
These may include:
Additional investigation and sampling.
Restrictions on agricultural or horticultural production.
Restrictions on grazing or animal feeding.
Prohibitions on particular crops.
Controls on access to contaminated areas.
Removal or replacement of contaminated soil.
Changes to land management practices.
Remediation or containment measures.
Long-term monitoring.
Where contamination poses a concrete risk to human, animal or plant health, authorities may restrict or prohibit the affected land use. Where remediation values are exceeded, remediation or permanent use restrictions may be required.
Important Deadlines
The VBBo does not establish one universal annual compliance deadline for all organisations. Compliance is generally continuous and project-specific.
Important timing requirements may include:
Before construction or excavation: Complete required soil investigations, sampling, soil-management plans and permit submissions.
During construction: Apply soil-protection, erosion-control and material-handling measures continuously.
After construction: Restore affected soil and complete any required inspections, documentation or monitoring.
Following identification of contamination: Carry out investigations, restrictions or remediation within the deadline established by the cantonal authority.
Before reusing excavated soil: Confirm that the soil is suitable for its proposed destination and intended use.
During remediation: Meet milestones and reporting dates specified in the official remediation decision.
Ongoing: Maintain compliance with land-use restrictions and monitoring requirements for as long as the relevant risk remains.
Deadlines are normally established through cantonal permits, enforcement decisions, remediation orders or project-specific environmental conditions.
Current Status
The Ordinance relating to Impacts on the Soil, commonly referred to as the VBBo and listed as SR 814.12, is in force as part of Switzerland’s federal environmental protection framework.
It was adopted on 1 July 1998 and entered into force on 1 October 1998. It replaced the earlier ordinance focused primarily on soil pollutants and expanded the framework to address chemical, biological and physical soil degradation.
The VBBo is implemented principally by the cantons, with the Federal Office for the Environment providing technical guidance, coordinating national soil monitoring and supporting consistent enforcement. The framework operates alongside:
The Environmental Protection Act.
The Contaminated Sites Ordinance.
The Waste Ordinance.
The Chemical Risk Reduction Ordinance.
The Waters Protection Act.
Cantonal planning, construction and environmental legislation.
The official legal framework continues to list the VBBo as a central legal instrument for Swiss soil protection.
Penalties for Non-Compliance
Administrative and Corrective Measures
Cantonal authorities may order responsible parties to:
Stop activities causing soil damage.
Carry out additional investigations.
Introduce protective or monitoring measures.
Restrict the use of affected land.
Remove, treat or replace contaminated soil.
Restore damaged soil.
Implement erosion or compaction controls.
Comply with revised permit conditions.
Remediate areas presenting unacceptable risks.
Authorities may also prohibit construction, excavation, agricultural use or soil reuse until the relevant risks have been addressed.
Remediation and Cost Liability
Responsible parties may be required to bear the costs of:
Soil sampling and laboratory analysis.
Site investigations.
Technical consultants and soil specialists.
Excavation and transport.
Treatment or disposal.
Replacement soil.
Site restoration.
Long-term monitoring.
Administrative enforcement.
Cost allocation may depend on causation, responsibility, ownership and the application of the polluter-pays principle under the wider Swiss environmental legal framework.
Permit and Project Consequences
Non-compliance can result in:
Refusal or suspension of construction approvals.
Stop-work orders.
Additional environmental conditions.
Restrictions on excavation or soil movement.
Rejection of proposed soil-reuse locations.
Delays to planning and infrastructure projects.
Withdrawal or modification of existing approvals.
Civil and Criminal Exposure
Serious or intentional breaches may lead to sanctions under the Environmental Protection Act or related cantonal and federal legislation.
Potential consequences include:
Administrative fines.
Criminal fines.
Prosecution for unlawful waste disposal or pollution.
Civil liability for damage to neighbouring land or property.
Compensation claims.
Liability for remediation and restoration costs.
The VBBo’s corrective measures are generally implemented through cantonal decisions, while penalties may arise under the Environmental Protection Act, waste legislation, water-protection rules or applicable cantonal law.
Examples of Known Violations
The following are representative examples of conduct that may breach the VBBo or related Swiss soil-protection requirements:
Improper Handling of Excavated Soil
A construction company excavates soil from a contaminated industrial site and mixes it with clean topsoil. The combined material is subsequently reused on agricultural land, spreading pollutants to a previously unaffected area.
Failure to Separate Soil Layers
A developer stores fertile topsoil together with subsoil, rubble and construction waste. The mixed material loses its structure and cannot be properly reused during site restoration.
Construction on Water-Saturated Soil
Heavy machinery is operated on wet soil without protective access routes or load-distribution measures, causing deep compaction and long-term damage to drainage, aeration and plant-growth capacity.
Uncontrolled Soil Erosion
A project leaves large areas of soil exposed without stabilisation, vegetation, drainage controls or sediment barriers. Rainfall transports soil and sediment into neighbouring land or watercourses.
Unauthorized Reuse of Polluted Soil
Excavated soil exceeding applicable contamination limits is reused in landscaping or residential development without investigation, approval or appropriate treatment.
Failure to Follow a Soil-Protection Plan
A contractor disregards permit conditions relating to machinery routes, storage areas, excavation depth or soil-restoration methods.
Agricultural Contamination
Repeated or excessive application of substances causes pollutant concentrations to exceed applicable soil values and threatens agricultural productivity or food safety.
Failure to Implement Required Protective Measures
A landowner or operator continues an activity after the cantonal authority has ordered restrictions, monitoring or remediation measures.
Failure to Investigate Suspected Contamination
A developer proceeds with excavation despite evidence of historic industrial contamination and fails to perform the required soil analysis before moving or reusing the material.
Breach of Land-Use Restrictions
Food crops, animal feed or grazing activities continue on land where the canton has imposed restrictions because contaminant concentrations may endanger people, animals or plants.
