What is asbestos in soil testing?

Asbestos in soil testing is the process of identifying and quantifying asbestos-containing materials (ACMs) that may be present in soil or bulk material samples. The test determines whether asbestos fibers are present, what type they are, and their concentration. This helps assess contamination levels and guides safe management, remediation, or disposal practices in compliance with environmental and health regulations such as the Control of Asbestos Regulations 2012.

Why is it important to test soil for asbestos?

Testing soil for asbestos is essential to protect public health and the environment. Asbestos fibers, when disturbed, can become airborne and pose serious respiratory health risks, including asbestosis and mesothelioma. Identifying contamination early allows landowners, developers, and contractors to plan safe remediation measures, reduce liability, and comply with environmental legislation before any construction or redevelopment begins.

How is asbestos testing in soil conducted?

Professional asbestos soil testing involves collecting representative samples from the site using industry-standard and UKAS-accredited procedures. Samples are carefully packaged and transported to a laboratory where analysts use techniques such as polarised light microscopy (PLM) and scanning electron microscopy (SEM) to detect and identify asbestos fibers. The results determine the type, quantity, and distribution of asbestos within the soil or material sample.

What types of asbestos can be found in soil?

The most common types of asbestos found in contaminated land are chrysotile (white asbestos), amosite (brown asbestos), and crocidolite (blue asbestos). These materials often originate from historical demolition waste, old building debris, insulation, or asbestos cement fragments that were buried or mixed into the soil during past construction or disposal activities.

When should I get my soil tested for asbestos?

You should consider asbestos testing whenever you suspect that soil or fill material might contain asbestos. This is especially important if: The site has a history of industrial or construction use. There are visible fragments of insulation, cement, or other suspect materials in the ground. You are planning redevelopment or excavation work. The land was previously used for manufacturing, waste disposal, or demolition. Testing at the outset of a project can prevent costly delays and ensure compliance with environmental and safety regulations.

How long does asbestos soil testing take?

The turnaround time for asbestos soil testing typically ranges from 24 to 72 hours once samples reach the laboratory. However, larger or more complex projects may take longer depending on the number of samples and required analysis methods. Many laboratories also offer express testing services for urgent assessments.

What happens if asbestos is found in my soil?

If asbestos is detected, the next step is to carry out a contaminated land risk assessment to determine the extent of contamination and potential exposure risks. Depending on the findings, a remediation plan may be required — this could include soil removal, encapsulation, or management under controlled conditions. All work must be carried out by trained, licensed professionals in accordance with the Control of Asbestos Regulations and environmental agency guidance.

Can I collect asbestos soil samples myself?

While technically possible, it’s strongly advised not to collect asbestos soil samples yourself. Improper sampling can disturb asbestos fibers, posing a serious health risk. Professional asbestos consultants are trained to safely collect samples using appropriate personal protective equipment (PPE) and containment procedures, ensuring that samples are representative and compliant with UKAS and HSE standards.

Is asbestos testing required by law?

Asbestos testing may be legally required in certain circumstances — particularly when developing, selling, or changing the use of potentially contaminated land. Under the Control of Asbestos Regulations 2012, duty holders must identify and manage asbestos risks to prevent exposure. Local planning authorities and environmental regulators may also require asbestos assessments as part of site investigation and remediation processes.

How much does asbestos soil testing cost?

The cost of asbestos soil testing depends on several factors, including the number of samples, site access conditions, and the speed of analysis required. As a general guide, prices typically range from £50 to £150 per sample, but comprehensive site assessments may require multiple samples and detailed reporting.

What is asbestos in soil?

Asbestos in soil is normally immobile, but when asbestos contaminated land is disturbed, fibres can be released. Asbestos can make its way into the ground in many different ways, such as historic buildings that have been demolished, which once contained asbestos, from previous building use, and fly-tipped waste. You may find asbestos broken up within the ground or buried in whole pieces. Asbestos containing materials (ACMs) may be present in soil as fragments or debris, and their identification is a key part of soil sampling and risk management.

The 2016 CAR-SOIL guidance interprets the Control of Asbestos Regulations 2012 to asbestos contaminated land and C&D Materials. The regulations require employers to reduce exposure and the spread of asbestos by carrying out risk assessments where works take place which involve asbestos. Asbestos risk assessment is essential to evaluate potential exposure and inform control measures during site works. Soil or waste contaminated with asbestos may be classified as hazardous under current regulations.

These regulations and guidance documents have been produced by regulatory authorities to ensure safe and compliant management of asbestos in soil. Asbestos in soil is considered a significant environmental issue due to its potential to contaminate land and pose health risks. Proper documentation, including the use of specific forms, is required during soil sampling and asbestos management procedures to ensure compliance and accurate record-keeping.

How do we test for asbestos in soil?

Prior to sampling, all vegetation (ground level) needs to be cleared, which should be undertaken by qualified professionals using hand tools, not power tools, to ensure safety and compliance. The area will also need to be damped down to control any fibre release.

Once the sampling strategy has been decided, i.e., gridding out the land and determining the depth of sampling using either trial pits, boreholes, or trenches, a 1kg (approx 1 litre) sample needs to be taken. Depending on the agreed survey strategy, the number of samples undertaken will be determined.

Oracle can carry out comprehensive asbestos surveys, soil sampling, and air monitoring for land development and remediation projects. If any ACMs are visible, these asbestos-containing materials are to be collected for laboratory analysis, given a unique sample reference, and sent to a UKAS-accredited lab alongside the soil samples.

While carrying out site investigations, air monitoring can be carried out depending on the site condition, weather, and exposure risk. The air monitoring and survey results will go towards formulating our recommendations for the site. We offer support and expert guidance throughout the asbestos management process to ensure compliance and safety.

All soil samples are thoroughly tested in accredited laboratories to determine the presence and concentration of asbestos.

For further information on regulatory requirements or procedures, clients can contact Oracle for guidance. Some asbestos-related tasks may be classified as non licensable work, so it is important to understand the regulatory distinctions and training requirements.

How is the asbestos in soil analysed?

Soil analysis for asbestos contamination is typically conducted through three stages: initial bulk analysis, gravimetric analysis, and fibre counting.

Stage 1: Initial Bulk Analysis – To determine if any visual fragments of Asbestos are present within the soil.

Stage 2: Gravimetric analysis to determine the mass and percentage of asbestos in soil by weight. Stage 2 will provide an overall weight % of asbestos present within the soil sample.

Stage 3: Fibre Counting and Sizing by Phase Contrast Optical Microscopy (PCOM) (Fine Fraction). This stage will provide a % of fibres present within the soil. During this stage, the aspect ratio (length-to-width ratio greater than 3:1) is used to distinguish respirable asbestos fibres under the microscope. The analysis also includes the identification and quantification of free fibres (free dispersed fibres) in the soil sample.

The results produced from these tests provide the percentage of asbestos fibres in the soil. The intended outcome of the analysis is to inform risk assessment and remediation decisions.

The above analysis will enable the client to:

Identify the total % of asbestos present within the soil
Identify the asbestos exposure to the contaminated land
Help with the determination of WAC (Waste Acceptance Criteria)

What is asbestos contaminated land bulk testing?

Where there are large amounts of visible bulk asbestos material on land, soil, or waste, it is usual to take a sample of the debris. These bulk samples are tested in accredited laboratories to confirm the presence of asbestos. This initial test is a convenient and cost-effective way to confirm that the debris is indeed asbestos prior to undertaking further tests. This type of sampling is called bulk testing and analysis. The sampling method and testing/analysis are the same as general asbestos bulk testing and analysis. Once you have confirmed if the material is asbestos or not, further testing and remediation can be considered.

Proper forms must be completed to document the sampling and testing process for compliance. The analysis will produce a report confirming the presence or absence of asbestos in the tested material.
