Soil and Groundwater Remediation Services Bristol

Understanding the most current remedial technology is not enough for successful delivery of a remediation project. Health & safety, demolition, construction programs, waste management, changing legislation and the clients’ objectives are all important factors. Soilfix prides itself on having skilled staff with the essential skills to deliver complete soil and groundwater services in Bristol.

Soilfix are a specialist soil remediation and groundwater company in Bristol who can manage your remediation projects from identification of the remedial requirement through to completion and final verification. Our team of in-house professionals can facilitate all stages of the remedial process, including design, site clearance, demolition, enabling works and regulatory approvals. Soilfix can finalise the works either in the role of principal contractor or as specialist sub-contractor.

Once we’ve understood our clients’ goals and objectives, we determine the best techniques and processed to carry out our remediation of soil and groundwater services.

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, resulting in asbestos contaminated soils (ACS) present in the ground.

This concern is typically enhanced 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 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 the relevant waste management legislation and Control of Asbestos Regulations (CAR) 2012. 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 carried out by either 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 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 larger quantities of material;
  • Stabilisation and / or encapsulation of ACS to minimise the possibility 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 Bristol 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 enhanced by altering the conditions within the soils that enable the relevant micro-organisms to both interact and thrive with the contaminants. The presence of nutrients and available carbon within the soil will provide the foundations for the organisms and can be artificially increased with the application of various fertilisers or bio-nutrient products. Optimising pH, temperature, moisture and oxygen conditions can increase 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 intensify the treatment process.

Stabilisation - Solidification Soilfix
Stabilisation Soilfix

Soil Stabilisation / Solidification Bristol

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 can encapsulate dangerous components, boost compressive strength, and reduce permeability by altering the physical characteristics of contaminated material.
  • Stabilisation changes the chemistry of certain hazardous constituents, making them less soluble, less mobile, and/or less toxic.

Prior to beginning the work,  samples of the contaminated 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 Bristol

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

With the help of qualified partners, Soilfix has also performed thermally enhanced treatment utilising both steam and electric conductive heating.
