Contaminated Land Risk Assessment
Contaminated Land Risk Assessment
Contaminated Land Risk Assessment is the process of evaluating the potential risks posed by contaminated land to human health, water resources, ecosystems, and property. It is commonly carried out as part of environmental site assessments, regulatory compliance, or land redevelopment projects.
Posing a threat to human health and the environment, contaminated land can create complex barriers to development. Assessing land for contamination and identifying potential risk from site use is essential for informed investment and development decisions.
Why is it important?
⦁ Protects human health and the environment from harmful pollutants.
⦁ Supports safe land redevelopment and urban planning.
⦁ Ensures compliance with environmental laws and regulations.
⦁ Prevents legal and financial liabilities for developers and landowners.
⦁ Protects human health and the environment from harmful pollutants.
We offer Contaminated Land Risk Assessments to support planning applications for all types of development throughout the UK.
Key Stages of Contaminated Land Risk Assessment:
Preliminary Risk Assessment (Phase 1 Desk Study)
A Phase 1 desk study that reviews historical land use, environmental records, and site inspections. It identifies potential sources of contamination, pathways, and receptors (the source-pathway-receptor model). Determines whether further investigation is needed.
Generic Quantitative Risk Assessment (GQRA)
GQRA involves soil, water, and gas sampling and laboratory analysis. Compares soil, water and gas concentrations with generic screening criteria or regulatory standards. It assesses whether contamination poses a significant risk.
Detailed Quantitative Risk Assessment (DQRA)
DQRA is a more in-depth evaluation using site-specific data and risk modelling. It helps determine the extent of contamination and potential long-term effects. It is used for decision-making on remediation (if considered necessary).
Remediation and Verification
If contamination exceeds acceptable levels, a remediation strategy is developed and implemented. Options may include excavation, soil treatment, groundwater remediation, or containment measures. Verification ensures that the remediation objectives have been met. After remediation, ongoing monitoring may be required to ensure contaminants remain at safe levels.
