An inductively coupled plasma - mass spectrometry (ICP-MS) method was developed to determine the [sup 129]I content in aqueous environmental samples. Due to interference from xenon, direct measurement of [sup 129]I could not be made on the ICP-MS. An ion-exchange technique is used to concentrate the Iodine from one liter samples to 30 mL. The 30 mL eluant from the anion-exchange column is then introduced to the ICP-MS. The detection limit of the procedure is [le]O.5 pCi/L. Several samples from the Savannah River near the Savannah River Site (SRS) have been analyzed for [sup 129]I by this procedure. Concentrations of [sup 129]I in the Savannah River ranged from 0.05[plus minus]0.12 to 0.21[plus minus]0.49 pCi/L (95% CL). Below a seepage basin, in Four Mile Creek on the Savannah River Site, [sup 129]I concentrations were as high as 2.31[plus minus]1.22 pCi/L. Before exiting the SRS the [sup 129]I concentration had decreased to 0.30[plus minus]0.16 pCi/L by dilution in Four Mile Creek.
