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.
