Contaminated
Land

Land regeneration is not simply a matter of cleaning soil and water and making land ready for use – it involves a process of assessment, planning and management. In our crowded country it should be considered as a continuing process rather than task to be accomplished just once for a given site.

It is furthermore obvious that the process of land regeneration is not just an attempt to return land to pre-industrial conditions it is much more a recognition that we must live with and on the inevitable consequences of our industrial civilization.

Contaminated
land

The term contaminated land covers a spectrum of conditions varying from those sites which satisfy the statutory definition of Part 2A of the Environmental Protection Act to those which have no significant effect on any party or environment. Similarly, the term covers sites for which the magnitude of contamination ranges from gross industrial pollution to minimal concentrations of natural or anthropogenic substances.
There is not, however, a one-to-one correspondence between the two spectra discussed above and detailed consideration of all the factors associated with a site are necessary to determine the correct approach. Following the DEFRA/EA model procedures for management of contamination allows a robust and repeatable approach to be adopted.

Asbestos control

Idom Merebrook have extensive experience of asbestos contaminated ground investigation and asbestos in buildings surveys.

All of our staff are asbestos awareness and NNLW (notifiable non-licensed work) trained and fully conversant with legislation and statutory instruments with regard to asbestos control and safe working practices.

In tandem with an MMP (Materials Management Plan), we can design bespoke asbestos management plans in order to minimise large costs associated with off-site disposal of asbestos contaminated soils.

We work closely with our preferred laboratory partners in order to select the most appropriate analytical techniques for asbestos detection and quantitation for each given situation, whether for waste classification or human health risk assessment.

remediation

A large range of remedial techniques is available to address any identified contamination issues at a particular site. Merebrook has long experience working with all established remediation methods but also has contributed to and cooperated on many innovative techniques in the UK. Being independent of any remediation contractor, we are able to offer impartial advice on the selection of suitable techniques.

In addition, it is considered that when clients instruct work on land remediation it is vital that expert advice is available to ensure that appropriate targets are clearly defined and that they are demonstrably met. Merebrook recognises the importance of procuring remedial works using suitable contracts and has long experience in the preparation and administration of these.

Risk Assessment

The correlation between the presence of hazardous materials or substances on or under land and the actual possibility that harm could occur to people, animals or ecosystems is complex. In order to make an appraisal of the link between these two, it is necessary and appropriate to undertake a formal assessment of risks. This takes the form of robust quantitative assessment of the physical factors describing the system but must also always be backed up by some elements of subjective judgment and estimation.

Merebrook undertakes quantitative and qualitative assessments of the risks associated with land and water contamination including Human Health Risk Assessment and Controlled Water risk assessment. Bespoke numerical models can be created for particular projects or situations for which accepted standard models are considered inappropriate.
