Risk assessment (INFO-RA)

Risk assessment is the formal process of identifying, assessing and evaluating the risks to health and the environment that may be posed by the condition of a site. If a site is contaminated, a risk assessment helps you decide whether it is a problem.

• Risk assessment - preliminary (INFO-RA1)

  Topics include: DOE Industry Profiles, Special Sites, Conceptual Site Models, information gathering and systems

• Risk assessment - Generic and detailed quantitative assessment (INFO-RA2)
• Risk assessment -general (INFO-RA2-1)

  Topics include: Introduction to data and tools

• Assessing risks to human health (INFO –RA2-2)

  Topics include: CLEA, SR2 & 3, Tox reports, SGVs, C4SLs, GACs, bioaccessibility and TPHCWG

• Assessing risks to the water environment (INFO-RA2-3)

  Topics include: Guidance on approaches and tools, GP3, R & D P20, ConSim

• Assessing risks associated with gases and vapours (INFO-RA2-4)
  

  Topics include: Approaches and Tools

• Assessing risks to ecosystems (INFO-RA2-5)
  

  Topics include: ERA framework, SSVs

• Assessing risks to buildings and services (INFO-RA2-6)
  

  Topics include: Approaches and Tools

Options appraisal (INFO-OA)

If an assessment shows there are unacceptable risks, you need to consider and evaluate feasible remediation options and determine the most appropriate remediation strategy for the site.

• Identification of feasible remediation options (INFO-OA1)
  

  Topics include: Remediation technologies, EA Remedial Treatment Data Sheets, Sustainable Remediation and Definition of Waste CoP

• Detailed evaluation of remediation options (INFO-OA2)
  

  Topics include: Remediation technologies, Cost Benefit Analysis

• Developing the remediation strategy (INFO-OA3)
  

  Topics include: Remediation technologies, Cost Benefit Analysis

Implementation of the Remediation Strategy (INFO-IMP)

Once a remediation strategy has been prepared you need to consider how to implement it. You also need to demonstrate that remediation has been and continues to be effective.

• Planning (INFO-IMP1)
• Implementation, verification and monitoring (INFO-IMP2)
  

  Topics include: EA Verification of Remediation

• Long term monitoring and maintenance (INFO-IMP3)
  

  Topics include: EA Verification of Remediation

Site Characterisation (INFO-SC)

In order to characterise the site it is important to design a survey which combines a number of requirements such as soil sampling patterns and frequency, groundwater investigations, the establishment of background levels of substances. It is also important to develop a conceptual model of the site at an early stage and to refine the conceptual model during the investigation programme.

• General (INFO-SC1)
  

  Topics include: Approaches, BS10175

• Sampling design (INFO-SC2)
  

  Topics include: Sampling Strategy and Guidance

• Field and laboratory analysis (INFO-SC3)
  

  Topics include: MCERTS, non intrusive techniques

Project Management (INFO-PM)

It is important that the remediation strategy is put into place in an effective and orderly manner that will deliver the remediation objectives agreed for the project. Health and safety need to be considered at the outset. Communication and consultation with relevant parties is an integral part of the plan.

• Guidance specific to particular industrial or commercial sectors (INFO-PM1)
  

  Topics include: ICRCL, R&D 66, gasworks, nuclear & defence, oil industry and brownfield

• Health and safety and quality management (INFO-PM2)
  

  Topics include: General Guidance

• Communication (INFO-PM3)
  

  Topics include: SNIFFER Guide, Stakeholder Involvement
