Professor Grundl and colleagues from the University of Washington have designed and built a set of X-ray fluorescence probes for a consortium consisting of Areva, an international mining company headquartered in France and Nagra, the agency in charge of the Swiss nuclear waste repository test site. Both probes were delivered in July 2015. Pictured above is Professor Grundl installing one of the probes into a borehole at a field site in south central France. The probe is capable of quantifying heavy metals in in-situ sediments within minutes at centimeter scale resolution. This negates the need for expensive laboratory analyses of laboriously collected sediment samples. Areva is using these probes for mining exploration and remediation tasks and Nagra is using them to conduct long term diffusion tests.

This is one of a series of field capable probes that the Grundl group has designed and built including a laser induced fluorescence probe for the quantification of PAH contamination in submerged harbor sediments and a previous X-ray fluorescence probe for heavy metals contamination in harbor sediments.
