Contaminated Land
Contaminated land represents a significant historical and long term environmental problem and the
introduction of increasingly stringent legislation, combined with the growing challenges to manage
environmental risk, present difficult choices to industry, developers and land owners. Whether you
are trading land or property, developing land for housing or industrial uses, benchmarking for ISO-14001,
or submitting applications for / complying with permits to operate an industrial process there are
legislative requirements and commercial responsibilities which must be met.
Our team of environmental specialists provides comprehensive contaminated land investigations, as well
as assessment and remediation advice that is tailored to your requirements, to ensure that legislative
requirements are met. We offer the following range of services:
Contaminated Land Investigations |
| Who is it for |
Property developers; house builders; structural engineers; facilities managers.
|
| What is it |
Phase I
A desk study carried out prior to an intrusive investigation to provide information with
respect to the site history, environment and the potential for contamination to have occurred
|
Phase II
An intrusive investigation to assess whether the potential contamination, identified by the
Phase I study, has affected the soil, groundwater and identified receptors
|
| What is involved |
A 'walk-over' site inspection and desk-based historical and environmental research and review
|
A range of drilling and sampling techniques to log ground condition, and recover soil and
groundwater samples. Samples are analysed in a UKAS accredited laboratory. Field work is undertaken
in general accordance with BS 10175(2001)
|
| Outcome |
Assessment of potential historical and current contamination, migration routes and sensitive receptors
applicable to the site. Preparation of a qualitative risk assessment report and conceptual model, with
recommendations for further work if required
|
Quantitative risk assessment and confirmation of Phase I findings. A detailed report with results,
conclusions and recommendations for risk reduction, contamination remediation, etc., to ensure that the site
is suitable for the intended end use
|
IPPC Site Condition Reports |
| Who is it for |
Operators of industrial processes and owners of installations
|
| What is it |
As part of the PPC application every installation is required to submit a report which describes the
site condition in terms of its historical and current soil and groundwater contamination. Before
the permit is surrendered the report is used as a reference point to compare contamination levels
(if present) from before and after the operation of the installation. There are three types of report -
Phase 1A, Phase 1B , Phase 2
|
| What is involved |
Phase 1A
A site reconnaissance followed by desk-based historical and environmental research and review
|
Phase 1B
A strategic (limited) intrusive investigation to assess whether the identified factors have
affected underlying soil and groundwater. A range of drilling and sampling techniques to log
ground condition, and recover soil and groundwater samples. Samples are analysed in a UKAS accredited
laboratory. Field work is undertaken in general accordance with BS 10175(2001)
|
Phase 2
Only required if any significant contamination which has been identified requires more accurate
delineation or further, more detailed, intrusive investigation
|
| Outcome |
Assessment of potential contamination sources, migration routes and sensitive receptors
applicable to the site. A conceptual model is prepared and the site is zoned on the
basis of all current and historical contamination sources prior to a qualitative
environmental risk assessment being undertaken, incorporating recommendations for further
work, if required.
|
The conceptual model for the site is developed and a quantitative risk assessment is
completed to define the risk of any identified contamination migrating and impacting upon
receptors.
|
Detailed multi-dimensional risk assessment.
|
Remediation and Validation; Due diligance, etc. |
| Who is it for |
Land owners, property developers, facilities managers
|
| What is it |
Site Remediation |
Due Diligence integral to the disposal or purchase of land or property |
Environmental Monitoring |
| What is involved |
Depending on intended use and based on findings of intrusive site investigations a strategy
and methodology is designed and implemented to control and minimise hazards and risks posed
by contaminated soil and groundwater. Field monitoring and sampling are undertaken to
confirm the effectiveness of the remedial work.
|
A desk based environmental review followed by a site inspection and an appraisal of current
or recent processes.
|
Gas and groundwater sampling and monitoring on landfill sites, land affected by industrial
activity or active installations.
|
| Outcome |
Validation report confirming the effectiveness of remediation works. |
A full identification of potential contamination sources and migration pathways; assessment
of associated hazards and risks; potential impact on the site and its owners.
Recommendations and costs for site investigation if significant hazards are identified [e.g.
asbestos or land/water contamination].
|
Detailed interpretative report showing status and comparisons against current legislative
limits and international standards.
