The US EPA, through the Environmental Technology Verification Program, is working to accelerate the acceptance and use of innovative technologies that improve the way the United States manages its environmental problems. This report describes the results of a field demonstration conducted at contaminated soil sites near Butte, Montana, in which developers of soil characterization technologies were invited to participate. Among these analytical methods, two related techniques were given emphasis, the anodic stripping voltammetry and the potentiometric stripping analysis, which are used to measure metals in solution. In these methods, elements are sequentially stripped in order of their oxidation potential. The length of time required to strip the element at a particular electrode is used as a measure of the concentration of the element in solution. The electrochemical stripping analyses were demonstrated along with three other participating technologies. The incorporation of conventional laboratory analysis into the demonstration provided a validated data set that could be used by the developers to evaluate the efficiency of the technology.
