TECHNICAL CONFERENCE – Application of appropriate site investigation methods have a significant impact on operational safety. Industry guidance documents help promote standards and inform the industry. This session demonstrates two new standards in general site investigation and the specifics of UXO clearance. This is followed by two papers on specific technologies for UXO clearance.
