    TECHNICAL REQUIREMENT AND SELECTION OF DRILLING AND SAMPLING TECHNIQUES FOR CONTAMINATED SITES BY CHEMISTRY AND MINING INDUSTRY

    • Drilling and sampling is an important step for the investigation and assessment of contaminated sites. This paper is based on the practical experience of site investigation in European and American Countries and the relevant technical literatures. It states that the quality of drilling and sampling,i.e., keeping physical and chemical intactness of samples, depends on the soil testing items required and the type of contaminants enclosed. Then it summarizes the advantages and disadvantages of the drilling methods being suitable for contaminated sites and their applicable soil types. The characteristics of the sampling methods being suitable for contaminated sites and the applicable samplers are also presented. Thereafter, a table is proposed for the selection of appropriate drilling and sampling methods for different types of contaminated sites. The table provides a guide for the site investigation of contaminated lands by chemistry and mining industry.
