Restoring hazardous waste sites

Article Abstract:

The failure of remedial measures at many of the hazardous waste sites (HWS) in the US indicates that consideration should be given to including ecological factors in design plans. There is urgent need to establish priorities according to comprehensive analysis and recording of the dangers from HWS, and for this reason site management work must be extended beyond its current boundaries. Ecological issues also need to be considered in relation to bioremediation, and should be made part of the remediation programmes which will be needed at many HWS, especially at western semiarid sites.

Improving remediation decisions at hazardous waste sites with risk-based geostatistical analysis

Article Abstract:

A study using risk-based geostatistical analysis aimed at improving remediation decisions at hazardous wastes sites is presented. The use of geostatistical analysis necessitates the identification of cancer risk for each sample taken. This sample-specific risk is utilized to produce maps of block-specific risk and links with models of site utilization to develop a quantity. The study shows the derivation of block-specific risk and shows how both this quantity and riskiness can be shown graphically to help in remediation decisions.
