This presentation explores responsible development through a broader lens, focusing on environmental, sustainability, and health impacts, exemplified by projects in London and Enfield. It delves into EIA, ecology, landscape, archaeology, water management, noise, air quality, and social-economic aspects. Discussions cover flood risk management, carbon emission reduction strategies, and sustainability schemes like BREEAM, EcoHomes, and CEEQUAL. The session highlights risk assessment methods for handling contamination, explaining the UK approach in four investigation phases, integrated with risk assessments at each stage. The framework includes Preliminary, Generic Quantitative, and Detailed Quantitative Risk Assessments, guiding remediation actions. The talk also examines remediation options and specialist tools for risk assessment, emphasizing the importance of a well-rounded approach for achieving sustainable outcomes.

Definition of Contaminated Landin the UK: Land which appears to the local authority to be in such a condition, by reasons of substances in, on or under the land that: So the definition of contaminated land is based upon the concept of risk assessment. (a) Significant harm is being caused or there is a significant possibility of such harm being caused, or (b) Pollution of controlled waters is being, or is likely to be, caused.
Investigation of Contaminated Land– UK Approach – The investigation of contaminated land is carried out in four phases, • Phase I - desk study, • Phase II - Intrusive investigation • Phase III - Remediation • Phase IV - Validation of remedial works Risk assessments are incorporated into these works at every phase
Risk Assessments The UK Risk Assessment Framework: Tier 1 -Preliminary risk assessment (PRA); Tier 2 -Generic quantitative risk assessment (GQRA); Tier 3 -Detailed quantitative risk assessment (DQRA) These tiers are incorporated into our phased investigations
Flowchart for the clean up process potential risks identified? Phase I – desk study and preliminary RA no Phase IIA – general intrusive investigation and generic QRA yes risks confirmed? no Phase IIB – targeted intrusive works and detailed quantitative RA yes residual risk? no yes Phase III – remediation no yes clean? No further action required Phase IV - validation
Tier 1–PRA at desk study – Phase 1 stage The risk assessment identifies: PATHWAYS RECEPTORS SOURCES Outcome: No further action required, or proceed to next tier???
Tier 2 - GQRA Compares contaminant levels in the soil or groundwater, with available generic guideline values such as; • CLEA SGVs • environmental quality standards The standards used depend on those acceptable to the respective local authority - performed during the Phase 2 investigation Outcome: No further action required, or Progress to Tier 3, or Remediate????
Tier 3 - DQRA Where necessary to reduce costs, a detailed QRA can be procured Performed at BTP investigation Phase IIb stage Additional work includes: • Bioavailability tests, • Leachate tests, • Use of specialist software programs (such as RBCA or SNIFFER)
Tier 3Use of specialist software for DQRA No further action required, or remediate????
Tier 3Use of specialist software for DQRA No further action required, or remediate????
