EVALUATION OF PERCHLORATE SOURCES IN THE RIALTO-COLTON AND CHINO CALIFORNIA SUBBASINS USING CHLORINE AND OXYGEN ISOTOPE RATIO ANALYSIS
Hatzinger, P.B., J.K. Boehlke, J. Izbicki, N. Teague, and N.C. Sturchio.
ESTCP Project ER-200942, 89 pp, 2015
Researchers evaluated the use of isotopic data to distinguish sources of perchlorate in groundwater in a specific region of the Rialto-Colton and Chino, California, groundwater subbasins. This region has two groundwater perchlorate plumes emanating from known military/industrial source areas, plus a larger area of measurable perchlorate outside the plumes. Isotope data indicate the presence of synthetic, Atacama (presumably from historical application of nitrate fertilizer in the region), and indigenous natural perchlorate in the study area. https://www.estcp.com/content/download/35669/341920/file/ER-200942-FR.pdf
