Contaminated Land Services
At AVADA Environmental we provide a wide range of contaminated land services and remediation services, including:
Phase 1 Preliminary Risk Assessment: Desktop Study
Desk study information is often the first building block of understanding the potential risks and liabilities that might be associated with a property due to historical or current contamination concerns and the information used to produce a Phase 1 Assessment will be used to establish the conceptual site model from which risks to sensitive receptors can be identified.
Phase 2 Site Investigation and Generic Risk Assessment (GQRA)
We provide a staged approach to land assessments which offers our clients with commercially focused solutions tailored to their business needs, whilst providing regulatory authorities with the documentation they require to satisfy the technical requirements of the planning process.
Phase 3 Site Specific Risk Assessment (DQRA)
We undertake Quantitive Risk Assessments where necessary to determine site specific remediation targets as part of our staged approach. This ensures the appropriate measures are undertaken to protect sensitive environmental receptors and discharge associated contaminated land planning conditions.
Remediation, Monitoring & Validation
We offer unbiased independent consultancy advice regarding the need for, and suitability of, any given remediation technique. We have an understanding of the technical and commercial challenges associated with remediation, development and land management, so we are able to identify the most appropriate remediation technology.
We can provide experienced consultants to work efficiently with the local authorities, Environment Agency and other regulators to negotiate planning approval, a remedial solution for a development, or agree the most cost-effective management programme for legacy contamination or routine monitoring requirements.
We have in-house capabilities in the following remediation techniques:
Physical remediation techniques including; excavation and disposal of contaminated soils in operational environments; installation of free product recovery trenches; active and passive methods of product recovery from groundwater; stabilisation/solidification for treatment of soil contamination.
Biological remediation techniques including; ex-situ soil remediation and in-situ groundwater remediation.
Chemical remediation techniques including; in-situ chemical oxidation for treatment of groundwater and ex-situ chemical oxidation for soil remediation.
