Summary
Details
- Austria
Mandatory for:
Landowners, operators, developers and organizations involved with contaminated land, brownfield redevelopment, waste disposal, industrial sites or activities that may create or manage contamination risks.
Entities subject to investigation, remediation, monitoring or cleanup obligations under Austrian contaminated-site regulations.
Waste-management operators and activities subject to the contaminated-sites levy (Altlastenbeitrag) where applicable.
Properties and activities with no contamination risk may not be directly subject to contaminated-site obligations, although environmental due diligence may still be advisable for transactions and development projects.

What's Required
Organizations may need to:
Assess contamination risks associated with land or facilities.
Cooperate with contaminated-site investigations.
Provide environmental information requested by authorities.
Comply with remediation orders where applicable.
Implement cleanup measures.
Monitor contaminated areas.
Manage contaminated soil and waste appropriately.
Prevent migration of contaminants into groundwater or surrounding environments.
Conduct environmental due diligence during acquisitions and redevelopment projects.
Follow reporting requirements established by authorities.
Developers and investors frequently undertake environmental assessments before purchasing or redeveloping land due to potential remediation liabilities.
Important Deadlines
Compliance obligations apply continuously where contamination is present or suspected.
Investigation and remediation deadlines are generally established by competent authorities on a case-by-case basis.
Reporting and monitoring requirements depend on site-specific remediation programmes.
Permit approvals may require contamination assessments before redevelopment can proceed.
Long-term monitoring obligations may continue after remediation activities are completed.
Current Status
The Austrian Contaminated Sites Act is currently in force.
ALSAG remains one of Austria's most important environmental remediation frameworks and has supported the cleanup of numerous contaminated sites across the country.
Austria maintains a structured contaminated-sites programme involving:
Identification of suspected sites.
Risk assessment.
Prioritisation of remediation measures.
Cleanup implementation.
Long-term monitoring where necessary.
The Act is supported by the Altlastenbeitrag, a contaminated-sites levy that helps finance remediation activities. The levy applies to certain waste-disposal and waste-management activities.
The framework is legally binding and plays an important role in brownfield redevelopment, environmental protection and groundwater management.
Penalties for Non-Compliance
Statutory fines
Non-compliance may result in:
Administrative fines.
Remediation orders.
Cleanup obligations.
Recovery of remediation costs.
Additional environmental investigations.
Restrictions on land development.
Permit delays or refusals.
Liability for environmental damage.
Civil claims.
Criminal consequences in severe environmental-damage cases.
The financial consequences can be significant where extensive contamination or groundwater remediation is involved.
Examples of Known Violations
As of June 2026, we were not able to identify a centralized Austrian database listing all enforcement actions under ALSAG.
However, common compliance issues include:
Failure to disclose contamination.
Improper handling of contaminated soil.
Illegal waste disposal.
Non-compliance with remediation requirements.
Failure to conduct required environmental investigations.
Breaches of permit conditions related to contaminated land.
Activities causing migration of pollutants into groundwater.
