ACMs in Soils: Contaminated Land
Asbestos-containing material (ACM) refers to any material that contains asbestos fibres. Asbestos is a naturally occurring mineral known for its heat resistance, strength, and insulating properties. Historically, it was widely used in various construction materials such as insulation, roofing, flooring, and cement products.
In the context of contaminated land and soil, ACM refers to any asbestos-containing materials that have been deposited or buried in the ground, potentially posing a risk to human health and the environment. When ACM is disturbed or deteriorates, it can release asbestos fibres into the air, which, when inhaled, can cause serious health issues including lung cancer, mesothelioma, and asbestosis.
The presence of ACM in soil can occur through several means, such as the improper disposal of asbestos-containing waste, the degradation of buildings or structures containing asbestos, or the use of asbestos-containing materials in landscaping or road construction.
Identification and Management of Asbestos-containing Material
Management of ACM in contaminated land and soil typically involves assessment, remediation, and proper disposal procedures to minimize exposure risks and ensure environmental safety. This may include encapsulation, removal, or containment strategies, depending on the extent of contamination and the intended land use.
