asbestos

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 concern is often 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 lead to significant potential liabilities, programme delays and accelerating costs for developers and landowners.

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

Works are either carried out by Soilfix properly skilled personnel 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 sustainable and cost-effective remedial measures are routinely carried out by Soilfix:

  • Selective excavation, sorting and in-situ manual picking of ACM fragments;
  • Manual picking and screening 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 Derby and the surrounding areas is carried out by our expert team. Numerous organic contaminants provide an energy source for naturally occurring micro-organisms present within the soil (e.g. bacteria). Under the right conditions, these organisms will degrade organic contaminants to form less toxic and/or more stable materials.

These processes can be excelled by altering 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 bio-nutrient products or fertilisers. Optimising moisture, temperature, 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.

The solutions that will allow you to achieve the highest rates of bioremediation at your site can be designed and built by Soilfix. 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 increase the treatment process.

Stabilisation - Solidification Soilfix
Stabilisation Soilfix

Soil Stabilisation / Solidification Derby

Stabilisation / Solidification of soils is increasingly a cost effective technology for the rapid treatment and / or immobilization of hazardous wastes and contaminated soils or sludge’s. 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 specific 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 carried out 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. This may involve testing for hydraulic conductivity, unconfined compressive strength, and leachate properties, depending on the requirements.

In-Situ / Ex-Situ Groundwater Treatment Derby

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

  • Total fluids recovery & ex-situ treatment using solids/NAPL separation, air stripping and filtration;
  • Surfactant-enhanced total fluids recovery through injection or groundwater recirculation;
  • Free-product recovery (with and without vacuum-enhancement) using dual-phase, pneumatic skimming and multi-phase vacuum extraction techniques;
  • 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,
  • Reduction technologies / in-situ chemical oxidation.

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