Abstract:
A system for detecting at least one conductive contaminant in unconsolidated materials comprising:at least one nonconductive section, wherein each section has an exterior surface and an interior surface, wherein a plurality of contacts, identified as first contacts or second contacts, are secured or disposed through the section such that at least 1.5 inches (3.8 cm) of each of the contacts extends above the exterior surface of one of the sections; an uncompleted electrical circuit comprising: at least one power source wherein each first contact is electrically connected to one power source; and at least one sensor wherein each second contact is electrically connected to at least one sensor and wherein at least one sensor is electrically connected to each power source; and wherein each contaminant in unconsolidated materials may be disposed within Â¼ inch (0.64 cm) of one of the first contacts and within Â¼ inch (0.64 cm) of one of the second contacts, thereby completing the circuit and activating at least one sensor.
