Contaminated Land.

Land contamination studies are required for brownfield sites, often to satisfy due diligence or in response to urban expansion and redevelopment.

David. Green is a land contamination specialist and has worked in many aspects of contamination assessment and soil management, beginning in 1988.  As a local authority inspector Dr Green began in this field of competence through soil contamination assessment at derelict industrial locations in inner London. These areas were proposed for residential redevelopment. David Gtreen planned and supervised the review of the historical uses of the sites and designed soil sampling plans, analysis and monitoring techniques for heavy metals and organic contaminants.  He has since planned conducted and supervised such studies to best international standards on numerous projects in UK, Hong Kong and Asia.

Soil or land contamination studies generally begin with a baseline historical review of past land uses, groundwater use in the area and the underlying geology. Available data on existing groundwater should also be reviewed.  Criteria for assessment and remediation are chosen to respond to accepted local and international standards, future land uses, local groundwater use and possible exposure of future land users.  

Based on the former land use and the site area two comlimentary study approaches can be taken. Where detailed evidence and plans are available, it is often possible to focus on the location of past industrial processes and sample at potential hot spots of chemical contamination. E.g. where the locations of oil storage tanks or coal stockpiles is known, sampling might focus on the analysis for petroleum based and organic compounds such as benzene and phenolics. Where the location of processes cannot be pinpointed or where spillage might be more likely, such as for wet processing in a former tannery site, sampling for indicator chemicals such as chromium would be based on a grid type aproach with the grid size based on the site conditions and dimentions ofthe site.  

Results will be compiled in a Contamination Assessment Report with recommendations for further samopling and a Remediation Plan will be compiled to guide the clean up of the site where necessary. Post remediation the results of decontamination processes will also be reported to confirm the acceptability of the site for future land ises.

David Green’s portfolio of land contamination studies since 1990 is extensive.  He has directed and managed numerous land contamination investigations and prepared remediation action plans for decontamination of major industrial locations such as municipal incnerators, power stations, gas works, steel works, shipyards and factories.
