ANALYTICAL RESULTS FOR THREE SOIL AND THREE WATER SAMPLES ASSOCIATED JWTH TI-IE SAN ONOFRE NUCLEAR GENERATING STATION, SAN CLEMBNTE, CALIFORNIA (INSPECTION REPORT nU 050-00206/06-015) [WTANQ. 06-OOI]
llie Oalr k d g e Institute for Science, i d Education (OIUSE) 1-eceived thee soil aiid tlx-ee n;ater saniples mociated with the Sail Onofi-e N~icle~ii-Generxing Station hi Saii Clemeiite, Gildoiiia on October 13, 2006. At your i-equest, the soil aiid water saiiiples were aidyzed by gammi spectroscopy (GS). The nciter saiiiples ma-e also analyzed for tiitium. The saniple ideiitiiicatioiis are listed hi Table I. Tlie GS and tritium data are pi-eseiited in Tables 2 a d 3, respectively Tlie pei-t-hienr procedure idemices :ire provided in the tables.
OIUSEs QLL~LLY Coiitrol (QC) requireemelits were met for these iiialyies. The QC files ire avdible ior your review upon request.
My coiitact hdonmtion is listed below. You may dso coiitict \\Vde Ivcy Lit 865.576.9 1S-l nidi einy questions or coiiuiients.
