Development of a Computerized Penetrometer System for Hazardous Waste Site Soils Investigations
Abstract
An instrumented cone penetrometer system has been developed for use in the investigations of soils at hazardous waste sites. The penetrometer is based on designs used for foundation investigations and includes instrumentation to measure tip penetration resistance, sleeve friction and electrical resistivity. The unit includes a computer-based data acquisition system that records input from the sensors and calculates indices related to the soil type. The resistivity module can detect the presence of soil contaminants that change the electrical properties of the soil. Field trials conducted with the penetrometer at Louisiana Army Ammunition Plant showed the penetrometer could be used to trace soil types and determine the extent of soil contamination at a closed waste-water evaporation pond. The penetrometer results were confirmed using standard soil sampling and laboratory analysis techniques. The penetrometer produced no cuttings that required disposal, and the unit could be rapidly decontaminated. Cone penetrometer, Hazardous wastes, Soils investigations.
