Investigation

An AES-Marconi Contaminated Land project follows the subsequent steps:

a) Commencement of Preliminary Investigation -

Phase I Survey
The Preliminary Investigation consists of a Desktop Study which may be sufficient itself to determine whether or not a site is contaminated. It examines the history of a site, using records such as maps, plans, photographs, geological and hydrological data to gain information about; past owners/occupiers, industrial or commercial uses, raw materials, disposal of waste arisings, site layout (above and below ground, including the provision of services) and any mining history.

b) Commencement of Phase II Survey
Phase II Surveys seek to assess the risks across any site, using a series of Targeted sampling bore holes and/or trial pits as well as other data to determine the nature of soils, groundwater and the link between any contaminants, pathways and ultimately receptors. Soil samples can then be taken and analysed to determine the concentrations of any potential contaminants.

Once any contaminants have been identified, risks assessed and the objectives of the investigation/end-use of the site are known, then any remediation strategy can be tailor made accordingly.

c) Remedial Strategy
Desktop Studies/Completed Reports are promptly submitted to Clients, the latter containing details on the extent of contamination present (if any), recommended remedial works, an outline of the extent of any physical disturbance to property and a quotation with regards to undertaking the recommended remedial actions.

d) Remedial Works
Provided that AES-Marconi’s recommendations and quotation are accepted, a team of specialist engineers and technicians would manage the operation using a combination of in-house expertise in both ex-situ and in-situ remediation techniques and waste management as well as working with 3rd parties if required.

e) Status Updates
During all survey and remedial works owner/occupiers are kept informed of progress

f) Completion of Works
Upon completion of any remedial works, a site is re-sampled to ensure efficacy. AES-Marconi will then supply a ‘Verification report’ of the work carried out for approval by the appropriate regulatory bodies. This report demonstrates the initial condition of the site, the remedial work undertaken an the sampling results generated post-remediation.
