ACHIEVING RESPONSIBLE DEVELOPMENT:

A WIDER PERSPECTIVE

RISK ASSESSMENT APPROACHES TO DEALING WITH CONTAMINATION

Definition of Contaminated Land

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 intothese works at every phase

Risk AssessmentsThe 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

Phase I – desk study and preliminary RA

SOURCES PATHWAYS RECEPTORS

No further action required,or proceed to next tier???

Outcome:

Tier 2 - GQRACompares 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

No further action required,or Progress to Tier 3,or Remediate????

Outcome:

Tier 3 - DQRAWhere 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????
