Aquifer Transport of Th, U, Ra and Rn in solution and on colloids
We have completed a theoretical study of the U-Th and radioactive decay series in an aquifer (Tricca et al, in press). Using this model as a guide, we have reassessed our results on the aquifer associated with Brookhaven National Laboratory. Based on our study and analyses of the U-Th series nuclei in this aquifer and the theoretical results, it was considered mandatory that a new set of samples be acquired. In addition to data from the groundwater samples, information concerning the addition of nuclides into the ground water system from the vadose zone was needed. A field study was then carried out and the samples returned to the laboratory. Sampling was done in consultation with hydrologists from the Brookhaven National Laboratory staff. The analyses are now almost completed and a draft of the final report is in preparation
