Environment & Natural Areas
Asbestos contamination in nature reserves, national parks, and protected areas.
Types of Facilities
Nature Reserves
Nature reserves may harbour asbestos contamination from former agricultural buildings, abandoned mining operations, illegal dumping of construction waste, and deteriorating infrastructure such as ranger stations, visitor centres, and boundary fencing built with asbestos cement materials.
National Parks
National parks face asbestos risks from historic buildings within park boundaries, naturally occurring asbestos in geological formations, legacy contamination from former industrial or mining activities, and ageing visitor infrastructure constructed during the mid-20th century.
Protected Zones & Conservation Areas
Protected environmental zones and conservation areas may contain asbestos from derelict farm buildings, former military installations, abandoned industrial sites, and naturally occurring asbestos deposits that can be disturbed by erosion, wildfires, or land management activities.
The Challenge
Environmental asbestos contamination represents a growing area of concern that extends far beyond the built environment. Asbestos occurs naturally in certain geological formations around the world, and human activities have spread asbestos-containing materials across landscapes through construction, demolition, industrial discharge, and illegal waste dumping. In natural and protected areas, asbestos contamination poses risks not only to human visitors and workers but also raises complex questions about ecosystem health and long-term environmental management.
Naturally occurring asbestos (NOA) presents particular challenges in environmental management. Geological formations containing chrysotile, tremolite, or actinolite can release fibres through natural weathering, erosion, landslides, and wildfire, creating airborne exposure risks without any human intervention. Climate change is intensifying these risks through increased wildfire frequency, altered erosion patterns, and more extreme weather events that disturb contaminated soils and rock formations.
The remediation of asbestos contamination in natural environments requires approaches fundamentally different from those used in buildings. Large-scale soil contamination cannot simply be removed and disposed of in the same way as building materials. Environmental monitoring, containment strategies, access restrictions, and long-term management plans must be developed in consultation with environmental scientists, conservation authorities, and public health agencies to balance ecological preservation with human health protection.
Regulation in your country
In United States, asbestos was banned in 2024. Buildings constructed before 2024 may contain asbestos materials and require professional assessment before any renovation work.

Natural and protected areas may contain asbestos from the following sources and materials:
- Naturally occurring asbestos (NOA) in serpentinite and ultramafic rock formations
- Contaminated soil from historical demolition waste used as fill or dumped illegally
- Deteriorating asbestos cement roofing on abandoned farm buildings and outbuildings
- Derelict structures from former mining operations with asbestos insulation and cladding
- Underground asbestos cement water pipes and drainage infrastructure
- Former military installations with asbestos in buildings, bunkers, and service infrastructure
- Asbestos-containing brake linings and friction materials in abandoned vehicles and machinery
- Contaminated sediments in waterways downstream from former asbestos processing sites
- Wildfire ash containing mobilised asbestos fibres from burned structures or NOA deposits
Services You Need
If you manage or are responsible for natural areas with potential asbestos contamination, the following professional services are relevant:
Key Regulations
European Union: The Environmental Liability Directive (2004/35/CE) establishes a framework for environmental remediation, including asbestos-contaminated land. Member states implement this through national legislation, with varying approaches to naturally occurring asbestos. The Habitats Directive and Birds Directive impose additional constraints on remediation activities within Natura 2000 sites.
United States: EPA regulations under CERCLA (Superfund) and RCRA govern the assessment and remediation of asbestos-contaminated land. USGS has mapped naturally occurring asbestos deposits across the country. The Libby, Montana Superfund site is a prominent example of environmental asbestos contamination requiring long-term remediation and public health monitoring.
Australia: The National Strategic Plan for Asbestos Awareness and Management addresses environmental contamination, including naturally occurring asbestos, legacy contamination from mining (particularly in Wittenoom, Western Australia), and illegal dumping. State regulations govern contaminated land assessment and remediation, with specific guidance for NOA management.
International: The Basel Convention regulates the transboundary movement of asbestos waste, including contaminated soil. The Stockholm Convention on Persistent Organic Pollutants, while not directly covering asbestos, provides a framework for managing persistent environmental contaminants. WHO guidelines address asbestos fibres in drinking water from environmental sources.
