STUDY NUMBER ; 10.4 



ORGANIZATION : University of Montana (UM), Geology Department 



TITLE OF STUDY ; Pathways of Metal Contaminant Transport in the 

 Clark Fork River; Warm Springs Ponds to Garrison 



CONTACT ( S ) ; Johnny Moore, University of Montana, Geology De- 

 partment, Missoula - 243-2341 



OBJECTIVE ; 1) Determine metal partitioning and fractionation 

 in bed sediments of the Clark Fork River. Specifically determine 

 what proportion of metals are carried by sulfides, oxyhydroxides , 

 organics and resistant crystalline compounds; 2) Establish the 

 relationship of grain size on metal concentrations; 3) Establish 

 the mechanisms of transport of metals in the river and the po- 

 tential for distribution and concentration in particular river 

 environments; 4) Determine the relative percentages of metals 

 carried in the bedload and metals carried in the sediments. 



DURATION ; 1987 - Indefinite 



CURRENT STATUS ; This project has been approved for funding by 

 the Water Resources Research Center. Field research is expected 

 to begin in the 1987 field season.
