ABSTRACT:

In industrialized countries one of the legacies of the past is contaminated ground due to mining, industry and society disposing of waste with little regard for future consequences. Frequently contaminated ground is associated with abandoned sites which occur within urban areas and as such are not compatible with the concept of sustainable development which calls for the re-use of such sites. The key to effective re-use of such land is harmonized management of ground investigation, risk assessment and clean-up strategies. One of the case histories considered involves a site investigation for a relief sewer in Glasgow, Scotland. As the site investigation progressed it ran into made-ground which contained waste from an old chemical works. The second case history involves the site of an abandoned coal mine in the Ruhr district of Germany, which had been operative for almost 90 years.

INTRODUCTION

One of the legacies of the past in industrialized countries is that land has been contaminated. Contaminated land has come about because industry and society tended to dispose of their waste with little regard for future consequences. It is land which contains substances which can cause harm to living organisms, pollute water or interfere with the ecosystem. It can take many forms, and can be variable in nature across a site and each site has its own characteristics. The key to effective rehabilitation of contaminated land involves the harmonized management of ground investigation, risk assessment and clean-up strategies. However, the accumulation of large amounts of data from various sources for a major site can represent a problem of processing. Digitization of data for the production of various site plans can be accomplished by a regular CAD application or a geographical information system (GIS). In addition, data can be represented in three-dimensions with the aid of a suitable work-station.
