The objective of this project is to design, build, deploy and test a field deployable instrument that can perform near-real time, fully autonomous measurements of uranium in contaminated groundwater plumes. The approximate dimensions of the deployable uranium analyzer are 2 x 2 x 4 feet. The system periodically samples water from existing aquifer tubes, and the samples are analyzed for uranium concentration using a colorimetric chelation system. Analytical results are sent wirelessly to a remote user. This activity is being funded by Department of Energy as part of a technology development project.
