Asbestos In Soils Testing Across the UK

Asbestos in soils cannot be reliably identified by the naked eye. It requires laboratory analysis in a UKAS accredited facility to determine whether asbestos is present, in what form and at what concentration.

The Testing Lab PLC (TTL) is UKAS ISO/IEC 17025:2017 accredited for asbestos in soils testing, providing identification and quantification of asbestos fibres in bulk samples of soil, aggregates and sediments, carried out in our purpose-built laboratory.

We support consultants, contractors and developers across the UK with robust data for risk assessment, management and waste classification on brownfield and contaminated land projects.

UKAS accredited asbestos in soils testing

Our accredited scope covers qualitative and quantitative analysis of asbestos in soils and construction & demolition (C&D) materials, in line with:

  • HSE guidance HSG248 – Asbestos: The Analysts’ Guide (2nd edition, including soils and made ground)

  • The SCA “Blue Book” method for identifying and quantifying asbestos in soils and associated materials

  • CAR-SOIL™ – the industry guidance interpreting the Control of Asbestos Regulations 2012 (CAR 2012) for asbestos-contaminated soil and C&D materials

TTL routinely participates in the Asbestos in Soils Scheme (AISS) proficiency testing programme run by HSE’s laboratory, which assesses the performance of laboratories undertaking qualitative and quantitative asbestos in soils analysis.

What is asbestos in soils?

“Asbestos in soils” refers to asbestos-containing materials (ACMs) and asbestos fibres present within soil, made ground or C&D materials. This can occur as:

  • Visible ACM fragments (e.g. cement, AIB, textured coatings)

  • Smaller debris mixed into made ground

  • Dispersed fibres within the soil matrix

Research has shown asbestos can be present in a significant proportion of made ground samples on brownfield sites.

Asbestos in soil presents a risk when fibres can be released into the air and inhaled, for example through excavation, earthworks, stockpiling, trafficking or wind erosion.

How asbestos gets into soil and made ground

Soil and made ground can become contaminated with asbestos in many different ways, including (but not limited to):

  • Historic demolition of buildings containing asbestos, with fragments left in made ground or backfill

  • Fly-tipping or illegal disposal of asbestos-containing materials

  • Redevelopment of brownfield sites with past industrial or commercial uses involving ACMs

  • Historic use of asbestos-contaminated fill, hardcore or demolition arisings

Due to the nature of asbestos fibres, once previously undisturbed ground is disturbed, the potential for fibre release and exposure increases, creating risks for workers, neighbours and the environment.

CAR-SOIL™ (Control of Asbestos Regulations 2012: Interpretation for Managing and Working with Asbestos in Soil and C&D Materials) requires employers to undertake appropriate risk assessment and control where there is a potential for exposure to asbestos in soils and C&D materials.

Our asbestos in soils testing methodology

TTL’s asbestos in soils analysis typically comprises three core stages:

  • Stage 1 – Identification (qualitative analysis)

    • Examination of the sample to identify any ACM fragments and dispersed asbestos fibres

    • Polarised light microscopy (PLM) and related techniques to identify asbestos types in accordance with HSG248

    • Qualitative assessment of the presence or absence of asbestos

    Stage 2 – Quantification of asbestos in soil

    • Application of recognised methods (e.g. SCA Blue Book) to quantify the mass percentage of asbestos present in the sample (w/w %)

    • Differentiation between ACM fragments and dispersed fibres where required

    • Results suitable for use in human health risk assessment and waste classification

  • Stage 3 – Respirable fibre content / dustiness assessment

    • Assessment of respirable asbestos fibre content in soils using phase contrast microscopy (PCM) or related methods where required

    • Allows better understanding of potential fibre release under site-relevant conditions, supporting risk assessments and the design of control measures

    Throughout the process we maintain full chain-of-custody and quality control, with results reported clearly and in a format suitable for consultants, contractors, regulators and wider stakeholders.

Using asbestos in soils data for risk assessment and waste classification

Our asbestos in soils results can be used to support:

  • 1. Human health risk assessment

    • Input to conceptual site models and risk assessment frameworks (e.g. SoBRA Asbestos in Soil Human Health Risk Assessment Toolbox)

    • Understanding of potential exposure pathways (workers, site users, neighbours)

    • Design of appropriate risk management and remediation strategies

    2. Waste classification and disposal

    • Determining whether excavated materials meet criteria for hazardous vs non-hazardous waste landfills – a major cost driver for earthworks and remediation projects

    • Supporting decisions on segregation, treatment, re-use or disposal options

    • Ensuring asbestos-contaminated wastes are consigned and disposed of in compliance with waste and environmental regulations

    3. Work categorisation under CAR 2012

    • Informing whether anticipated site activities are likely to be licensable, notifiable non-licensed work (NNLW) or non-licensed work, once combined with exposure assessment and CAR-SOIL guidance

Our technical team can work with your geo-environmental and H&S advisers to interpret the results in the context of CAR 2012, CAR-SOIL and project-specific risk assessments.

Frequently asked questions about asbestos in soils

  • How is asbestos in soils tested?
    Typical testing involves a combination of:

    • Visual inspection and separation of suspected ACMs

    • Laboratory identification of asbestos using microscopy (in accordance with HSG248)

    • Quantification of asbestos content (mass %) in line with methods such as the SCA Blue Book

    • Optional assessment of respirable fibre content or dustiness where required for risk assessment.

  • When do I need asbestos in soils testing?
    You should consider testing whenever there is a reasonable suspicion that soils, made ground or C&D materials may contain asbestos, for example on brownfield sites, former industrial/commercial areas, or where visible ACM fragments are present in trial pits, boreholes or stockpiles. Testing is essential to inform risk assessment, management and waste classification.

  • What guidance applies to asbestos in soils?
    For UK projects, the primary guidance is CAR-SOIL™ – Control of Asbestos Regulations 2012: Interpretation for Managing and Working with Asbestos in Soil and C&D Materials, supported by HSE’s HSG248 (The Analysts’ Guide) and wider contaminated land / waste guidance.

  • Does asbestos in soil always pose a risk?
    Asbestos in soils presents a risk mainly when fibres can become airborne and be inhaled, for example during excavation, earthworks, trafficking or wind action on dry, dusty material. Good practice risk assessment and management can often control these risks without wholesale excavation, depending on site conditions and proposed end use.

  • How quickly can I get asbestos in soils results?
    Turnaround depends on the number of samples, analysis type (qualitative only vs full quantification and respirable fibre assessment) and project urgency. We offer flexible options and will confirm timescales at quotation stage, with all analysis carried out in-house under our UKAS accreditation.

TTL have been working directly as my analyst for the last 12 months on a very complex asbestos removal scheme, they have achieved all of their KPI’s without fail and on a number of occasions surpassed their SLA in acting for us on planning issues associated with the demolition in regard to contamination which cannot be removed as part of the normal sequence of operation.

 

There reports are always issued within timescales and they have policed the reports by the Licensed asbestos contractor faultlessly sometimes in very difficult circumstances.
