I h r Mr. Sncll 1 lic Oak Ridge Institute for Science and Education (0KISli)rcccivcd eight watcr samplcs in Hatch
'I'lircc on April 20, 2006 that were collected in the vicinity of thc Hyron Generating Station in l3yron.
Illinois. l h e samples were analyzed for tritium using a liquid scintillation analyzer (l'roccdurcs AI'?,
I<cvision 15 and CP4, Ilevision 3). The chain of custody identified two watcr samplcs t<i be analyzcd b y gamma spectroscopy (GS) (Procedure CP1, Revision 15). ?'he samplc identifications and collcction data arc prcsentcd in l'able 1. The GS data are prescntcd in Table 2. l h c tritium data arc prcscntcd in l'ablc
