OBJECTIVE : Accurately identify surface water, groundwater, tail- 

 ings and point source problem areas; evaluate potential remedial 

 actions and, eventually select a preferred alternative to rectify 

 contamination in the Silver Bow Creek/upper Clark Fork system. 



DURATION ; 1984 - Indefinite 



CURRENT STATUS ; With the designation of Silver Bow Creek as 



a Superfund site in 1982, the Anaconda Minerals Company and their 



consultants began collecting preliminary information on the extent 



and severity of contamination in the area. This information, 



in part, was used to develop a work plan for the Silver Bow Creek 



Remedial Investigation (RI), which began in September, 1984. 



Water quality, soils and biological data were intensely collected 



until December, 1985. 



Subsequent to the completion of the Phase I RI, feasibility 

 study efforts were begun. Detailed planning has been completed 

 and feasibility studies for the various problems encountered 

 at the site may be initiated as soon as funding becomes available. 



Concurrent with the initiation of feasibility studies, ad- 

 ditional RI efforts have been initiated to answer questions aris- 

 ing from the first phase, correct data deficiencies and provide 

 specific information necessary to complete feasibility studies. 



Extensive delay in CERCLA reauthorization has had a sig- 

 nificant affect on site progress. Lack of funding has delayed 

 this project by one year. 



fUTURE ACTIVITIES ; Site expansions both into the headwaters 

 and downstream and an ongoing attempt to integrate CERCLA act- 

 ivities at all Clark Fork Superfund sites into a technically 

 supportable and manageable sequence make it difficult to predict 

 future action dates with any accuracy at this point. However,
