摘要

The International Association of GeoChemistry has selected a paper authored by Environmental Radiochemistry Group members Keara Moore, Brenda Ekwurzel, Brad Esser, Bryant Hudson, and Jean Moran as the recipient of the Hitchon Award, a new international prize. The paper, "Sources of Groundwater Nitrate Revealed Using Residence Time and Isotope Methods," was recognized as the most important piece published last year in Applied Geochemistry, the association's monthly journal. The research leading to the paper, performed at Lawrence Livermore on local groundwater, involved using isotopic tracer techniques to examine groundwater flow patterns and timing of nitrate inputs to groundwater. Research results suggest that synthetic fertilizer and naturally occurring nitrogen in soil are more significant sources of groundwater nitrate contamination than previously thought.
