Asbestos in Soil Remediation

Remediation & Contaminated Land › Specific › Asbestos in Soil Remediation

Presenter		Project
Location		Date

Asbestos in soil is found on sites where buildings containing asbestos have been demolished and the debris buried or spread.
Asbestos fibres in soil become airborne when the ground is disturbed by excavation, loading, tipping, or vehicle movements.
The Control of Asbestos Regulations 2012 apply to asbestos in any form, including fibres bound in soil and made ground.
A site investigation must identify the type, concentration, and distribution of asbestos before remediation work begins.
Soil with asbestos concentrations above threshold levels must be excavated, handled, and disposed of as hazardous waste.
Dust suppression using water sprays is critical during excavation, loading, and transport of asbestos-contaminated soil.
Workers handling asbestos-contaminated soil must wear RPE (minimum FFP3), disposable coveralls, and be decontaminated after each shift.
Decontamination units with clean and dirty zones must be provided at the boundary of the contaminated work area.
Air monitoring by a qualified analyst must be carried out during and after remediation to confirm fibre levels are controlled.
Disposal of asbestos-contaminated soil must be through a licensed waste carrier to a permitted hazardous waste landfill.

Fibre release	Disturbing soil containing asbestos releases microscopic fibres that cause mesothelioma and lung cancer with no safe exposure level.
Widespread contamination	Asbestos in soil can spread across a site through vehicle movements and wind, contaminating areas thought to be clean.
Legal duty	Asbestos waste in soil is subject to the same strict regulations as asbestos in buildings — the penalties for non-compliance are severe.

Don't

Complete the site investigation to identify asbestos type, extent, and concentration.
Prepare a remediation method statement covering excavation, handling, and disposal.
Suppress dust continuously with water sprays during all soil disturbance activities.
Wear FFP3 RPE and disposable coveralls when working in the contaminated area.
Use decontamination units at the work zone boundary after every shift.
Arrange air monitoring by a qualified analyst throughout the remediation works.
Dispose of contaminated soil through licensed carriers to permitted hazardous waste sites.
Mark the contaminated area boundary clearly with signs and physical barriers.
Damp down vehicle routes to prevent asbestos-contaminated dust spreading across the site.
Brief all workers on asbestos-in-soil hazards and the decontamination procedure.

DON'T excavate soil known to contain asbestos without a remediation method statement.
DON'T disturb contaminated soil without continuous water suppression to control dust.
DON'T work in asbestos-contaminated soil without FFP3 RPE and disposable coveralls.
DON'T leave the contaminated work zone without passing through decontamination.
DON'T continue work if air monitoring shows fibre levels above the control limit.
DON'T dispose of asbestos-contaminated soil in standard waste skips or facilities.
DON'T allow vehicles to spread contaminated soil beyond the marked work area.
DON'T enter the contaminated zone without the required PPE and authorisation.
DON'T take contaminated clothing or equipment out of the designated work area.
DON'T assume soil is clean because it looks clean — only analysis confirms the status.
