Western Environmental is a leading environmental consultancy providing a range of inspection and investigation services to identify hazardous materials, including asbestos. Our approach and services are extensive and include the initial sampling and analysis for asbestos and hazardous materials, ongoing compliance, risk management and project management of remediation.


A Hazardous Materials Survey comprises an inspection and report on building structures for materials likely to be hazardous to human health and the environment. Hazardous materials identified through our survey can include but are not limited to:

  • Asbestos Containing Material (ACM).
  • Lead.
  • Polychlorinated Biphenyls (PCBs).
  • Synthetic Mineral Fibres (SMF).
  • Chlorofluorocarbons (CFCs).

A Hazardous Materials Survey fulfils your obligations as a building manager or owner by:

  • Meeting your occupational health and safety legislative requirements to protect workers and building occupiers from asbestos materials.
  • Meet legislative requirements for the register and management of asbestos in the workplace under the Occupational Health and Safety Regulations 1996.
  • To comply with the Australian Standard AS2601-2001: The Demolition of Structures.
  • General due diligence for property buyers, sellers and developers.
  • Meet development approval.


Asbestos is a naturally occurring substance that was extracted as fibres and added to products or other materials. In Western Australia, asbestos was extensively used in buildings and other products into the 1980s. Crocidolite asbestos, primarily used in asbestos-cement products, was extensively mined at Wittenoom until the mine ceased operation in 1966. Imported amosite asbestos was also used in these products until 1984, and chrysotile asbestos until 1987.

Asbestos is no longer being produced, as it can cause serious health issues. Asbestos itself can be carcinogenic; fibres can be released from disturbed materials, and these can be inhaled and remain in the lungs forever. These fibres can cause health problems later in life, such as lung scarring, mesothelioma, and lung cancer. However, these typically only occur after prolonged exposure, so while avoidable interactions are not healthy, if asbestos is properly managed the health risks may be avoided.

Contaminant asbestos can be in a range forms, sizes and degrees of deterioration and can be divided into three groups: Asbestos Containing Material (ACM), Fibrous Asbestos (FA) and Asbestos Fines (AF).


The common use of asbestos as a building material until the mid to late 1990s means it is regularly identified in buildings that were constructed or renovated prior to this time.

Regulation 5.43 of the Occupational Safety and Health Regulations 1996 requires that the employer, main contractor, self-employed person or person in control of the workplace identifies the presence and location of asbestos at the workplace and assesses the health risks. This needs to be in accordance with the Code of Practice for Management and Control of Asbestos in Workplaces [NOHSC: 2018(2005)]. This information is to be recorded in an Asbestos Register. If the ACM presents a health risk, the employer or person in control of the workplace has a duty of care under the Occupational Safety and Health Act 1984 to implement controls.

The Asbestos Register is used to communicate the hazard before work commences and a safe system of work must be used for tasks that may disturb ACM. The Asbestos Register and associated risk assessments must be reviewed at least every three years. Warning signs and labels supplement the information on an Asbestos Register and must be used as part of a safe system of work.


The legacy of many old building materials containing asbestos, combined with urban redevelopment and implementation of the Contaminated Sites Act 2003 (CS Act), has resulted in asbestos-contaminated sites becoming an important health risk and management issue. ACM in soil is the most common form of asbestos site contamination in Western Australia due to its historical widespread use as uncharacterised fill material for site landscaping, dumping as debris on vacant or development sites and inadequate removal and disposal of asbestos products during building demolitions. Degradation and subsequent dissemination of asbestos material has required many sites to be subject to contamination assessment and management in accordance with DoH (2009) Asbestos Guidelines. Adherence to these guidelines will help avoid costly and unnecessary delays associated with such activities including any redevelopment projects.

Mine closure planning aims to ensure resource industry activities are designed, operated, closed, decommissioned and rehabilitated in an ecologically sustainable manner, consistent with agreed environmental outcomes and end land-uses and without unacceptable liability to the State of Western Australia. Knowledge gaps that limit the development of final rehabilitation strategies are often present, such as:

  • Closure objectives and goals not being clearly defined;
  • Lack of material characterisation and volume data;
  • Unknown interaction between landforms and water;
  • Inadequate flora and fauna investigations;
  • Insufficient data to show success of rehabilitation undertaken or trigger remedial works;
  • Potential contaminated sites;
  • Potential impacts to the receiving environment; and
  • Insufficient detail related to decommissioning works and final landforms.

WEPL can assist to overcome these knowledge gaps for your site, ensuring that the right information is obtained before mining commences and that adequate planning continues throughout the life of the mine until final closure and relinquishment to enable better environmental outcomes and avoid the need for costly remedial earthworks late in the project lifecycle.

WEPL team of in-house environmental professionals and specialist sub-consultants have considerable experience undertaking the range of activities needed to rehabilitate a mine site in order to be (physically) safe to humans and animals, (geo-technically) stable, (geo-chemically) non-polluting/non-contaminating, and capable of sustaining an agreed post-mining land use, including investigations related to:

  • Hazardous materials;
  • Hazardous and unsafe facilities;
  • Contaminated sites;
  • Acid and metalliferous drainage (AMD);
  • Radioactive materials;
  • Fibrous (including asbestiform) materials;
  • Non-target metals and target metal residues in mine wastes;
  • Management of mine pit lakes;
  • Adverse impacts on surface and groundwater quality;
  • Dispersive and sodic materials;
  • Erosive materials;
  • Design and maintenance of surface water management structures;
  • Dust emissions;
  • Flora and fauna diversity/threatened species;
  • Challenges associated with rehabilitation and revegetation
