Summary:The actual hydrocarbon thickness can be directly measured by a new tool. The design incorporates five-foot long stainless steel rods with a hydrocarbon-sensitive indicatior strip and electronics to locate the water table. The 3/4 inch diameter probe can be hand driven to depths up to 15 feet. The tool's electronics signal when the water table has been reached. The probe is left in place approximately 20 minutes to allow mobile hydrocarbons to be adsorbed by the indicator strip. The strip is permeable to organic solvents and to oil, but it repels water. A color change is evident wehre hydrocarbons have been absorbed. When the tool is removed from the ground, the product thickness and depth are recorded. The probe field tested well at the site of a pipeline spill. Measurements were in close agreement with measurements taken in an excavated pit, bailer test analysis, and a density adjusted CONCAWE formula.—Modified journal abstract.
