Anderson has published an extensive array of scientific journals and has presented at technical symposia, which include:. Bradley Suedbeck. Baseline groundwater monitoring studies help mining companies evaluate the extent and concentration of NORM at their operating sites. The EPA expects to finalize the rule by December of In the ISR process, oxidizing chemical solutions are pumped through injection wells into the ore body where the uranium is solubilized. The uranium-rich solutions are pumped to the surface through extraction wells, then piped or transported to a processing plant where the uranium is recovered and further processed prior to shipment.

Currently, facilities are required to monitor groundwater conditions for less than 2 years after restoration. There is a potential for uranium and other constituents to remobilize over time, with the potential for groundwater contamination. The proposed rule will modify the current monitoring requirements to more fully establish baseline conditions, demonstrate restoration, and to demonstrate that the restored water quality is stable. Eurofins TestAmerica supports the analysis of the 13 constituents for which groundwater protection standards have been proposed: arsenic, barium, cadmium, chromium, lead, mercury, selenium, silver, nitrate as N , molybdenum, combined radium and radium, uranium total , and gross alpha-particle activity excluding radon and uranium.

We provide a variety of analytical options for the determination of radioactive constituents in groundwater as well as wastewater, soil and solid waste. With more than 30 years of radiochemistry testing expertise, Eurofins TestAmerica provides full service radiochemistry testing support for mining operations throughout the United States.
