ASBESTOS 
CONTAMINATED
SOILS

Asbestos is widespread in the environment. It may enter the atmosphere due to the natural weathering of asbestos-containing ores or damage and breakdown of asbestos-containing products. 

The human health risk from asbestos-contaminated soil varies considerably depending on the form of asbestos, its quantity, and its exposure situation. For instance, large amounts of free-fibre asbestos on the surface of a residential lot would be considerably more dangerous than asbestos incorporated in a cement pipe buried beneath a commercial property. This is because the fibres can more readily be disturbed and inhaled in that residential situation and exposure theoretically maybe for 24 hours a day for a lifetime. 

Furthermore, asbestos can also be introduced into soils due to a result of poorly managed asbestos removal works, for instance resulting in the breakup of asbestos roofing sheets or pipe lagging during removal. Left uncontrolled, such fragments may become incorporated into soils or waterways where they might spread further or be transported to other sites. There is also the possibility for historical buried asbestos to be disturbed by later earthworks or construction, leading to its distribution within media such as soil.

The toxic effects of asbestos are well recognized and primarily result from the inhalation of free fibres. Due to its toxicology, transport and degradation properties, and physical form, asbestos presents a unique contamination challenge.

The site-specific site management plan provided by Protec Consulting will be formulated following the Health and Safety at Work (Asbestos Regulations: 2016), Resource Management (National Environmental Standard for Assessing and Managing Contaminants in Soil to Protect Human Health) Regulations 2011 (NES-CS and New Zealand Guidelines for Assessing and Managing Asbestos in Soils: 2017 (BRANZ soil guidelines)

Protec Consulting has experienced personnel to provide services for investigation, management, or remediation of residential properties with asbestos contaminated soil.
