外文摘要：Several former coke works sites in north-eastEngland are under consideration for redevelopment forresidential or commercial use. In some instances thecontamination from the coking processes has spread off-sitethrough groundwater and investigations have been undertaken toascertain the extent of contamination. This paper focuses on onevery large site covering 91 hectares, Hawthorn Colliery, wherecontamination may have spread onto the so-called HawthornReserve Site through groundwater movement Details ofinvestigations and proposed remedial measures are provided. AtHawthorn the services of an industrial archaeologist wereengaged to research details of the actual operations at the collierysince their commencement in 1957. This enabled the siteinvestigation to be focused on areas of highest contaminationpotential. A phased approach to the investigation was carried outand at the end of each phase both the geological andcontamination aspects were assessed and examined thoroughly inorder to economically plan each subsequent phase. Theinvestigation concentrated on locating the thickness and extent ofsand and gravel layers within the glacial till and determining thepermeability of these layers, as these layers provide a potentialconduit for contaminants from the former colliery site to theadjacent Reserve Site.
