Asbestos in Soils & Demolition Materials

An increasingly common legacy of former industrial sites is the presence of asbestos containing materials (ACM’s) deposited or dispersed within made ground, leading to asbestos contaminated soils (ACS) present in the ground.

This problem is typically exacerbated by poorly managed demolition practices, resulting in ACM fragments becoming spread across the site surface and/or throughout crushed materials. The presence of ACM’s and ACS can result in significant potential liabilities, programme delays and escalating costs for landowners and developers.

Soilfix has extensive experience in adopting pragmatic, robust yet cost-effective solutions for asbestos contaminated sites, fully in compliance with the relevant waste management legislation and Control of Asbestos Regulations (CAR) 2012. Through careful planning of pre-treatment and materials management requirements, the volumes of hazardous and non-hazardous wastes removed off-site can be minimised.

All asbestos removal works are carried out by either Soilfix employees with the necessary training under a Notifiable Non-Licensable Works (NNLW) Notification, or, where higher risk ACM’s are encountered, carried out using a licensed Asbestos Contractor. The following cost effective and sustainable remedial measures are routinely carried out by Soilfix:

  • Selective excavation, sorting and in-situ manual picking of ACM fragments;
  • Screening and manual picking of ACM fragments, in an enclosed picking station for higher quantities of material;
  • Stabilisation and / or encapsulation of ACS to minimise the extent for residual fibre release;
  • Stringent environmental monitoring and controls, including fine-mist (virtual enclosure) suppression systems, reassurance air testing and scanning electron microscopy analysis to confirm airborne fibre concentrations are below HSE control limits as well as environmental background levels.

All Soilfix staff working with asbestos are Non-licensed/Notifiable non-licensed work trained and have regular medicals and respirator face-fitting to ensure compliance with CAR2012.

bioremediation Soilfix

Bioremediation

Our specialist bioremediation service in Preston and the surrounding areas is carried out by our expert team. Numerous organic pollutants provide an energy source for naturally occurring micro-organisms existing in the soil (e.g. bacteria). Under the right environment, these organisms will degrade organic contaminants to form less toxic and/or more stable materials.

These processes can be enhanced by manipulating the conditions within the soils that enable the relevant micro-organisms to both thrive and interact with the contaminants. The soil’s availability of carbon and nutrient content within the soil will provide the groundwork for the organisms and can be artificially increased with the application of various fertilisers or bio-nutrient products. Optimising temperature, moisture, pH and oxygen conditions can expand populations and enable maximum interaction with the contaminant.

Biorememediation can be accelerated within ex-situ soils using vented biopiles or windrow technology. Bio-venting, sparging or permeable reactive barriers (PRBs) can be used to accelerate the process in-situ.

Soilfix can design and build the systems that will enable you to achieve maximum rates of bioremediation at your site. Where more complex contaminant situations, gross start concentrations or biomass limited situations occur, Soilfix has experience in bio-augmentation using both specially cultured and indigenous biomass to boost the treatment process.

Stabilisation - Solidification Soilfix
Stabilisation Soilfix

Soil Stabilisation / Solidification Preston

A increasingly affordable technology for the quick treatment and/or immobilisation of hazardous wastes and polluted soils or sludge is soil stabilisation or solidification. The terms “solidification” and “stabilization” describe two specific mechanisms.

  • Solidification changes the physical properties of contaminated material to increase its compressive strength, decrease its permeability, and encapsulate hazardous constituents.
  • Stabilisation changes the chemistry of particular hazardous constituents, making them less soluble, less mobile, and/or less toxic.

Prior to commencing,  samples of the corrupt material are taken and laboratory pilot trials conducted to calculate the most cost effective reagent or combination of reagents to achieve the site remedial targets. Binding agents are then applied and the soils rotivated either in-situ (e.g. auger, injection, rotivator) or ex-situ (e.g. batching plant, blending equipment). Performance testing of the treated materials is usually completed throughout the works. Depending on requirements this can include tests on hydraulic conductivity, unconfined compressive strength and leachate characteristics.

In-Situ / Ex-Situ Groundwater Treatment Preston

Soilfix has extensive experience in adopting a large variety of both conventional and more innovative in-situ / ex-situ groundwater treatment technologies in Preston to meet site specific remedial objectives and / or enable excavation and removal of in-ground obstructions.

  • Using air stripping, filtration, and solids/NAPL separation for total fluid recovery and ex-situ treatment;
  • Surfactant-enhanced total fluids recovery through injection or groundwater recirculation;
  • Free-product recovery (with and without vacuum-enhancement) using pneumatic skimming, dual-phase and multi-phase vacuum extraction systems;
  • Air sparge / SVE systems (including use of ozone);
  • Enhanced natural attenuation techniques for both aerobic and reductive treatment to stimulate accelerated biodegradation (for solvents, trace organic compounds and hydrocarbons) or precipitation (e.g. hexavalent chromium); and,
  • In-situ chemical oxidation / reduction technologies.

Soilfix also has experience in carrying out thermally-enhanced treatment using both steam and electric conductive heating using specialist partners.
