The Montana Department of Health and Environmental 

 Sciences has lead responsibility for Silver Bow Creek and the 

 upper Clark Fork investigations. Phase I of the remedial 

 investigation (RI) , completed in 1986, included the study of 

 surface water and point sources, tailings, ground water, 

 algae, agricultural lands, macroinvertebrates, bioassays, 

 fish tissue, waterfowl, vegetation, and the Warm Springs Pond 

 System. Phase II remedial investigations are now underway to 

 gather remaining information needed to complete the feasi- 

 bility study (FS) , in which remedial actions for the site 

 will be chosen. Phase II RI/FS activities include a 

 screening study along the upper Clark Fork, additional 

 studies of the Warm Springs Ponds system, a flood hydrologic 

 evaluation of Silver Bow Creek, and a streambank tailings and 

 revegetation study (STARS) designed to explore a range of 

 reclamation alternatives for the drainages. 



Contaminants of concern in the Silver Bow Creek site 

 include arsenic, cadmium, copper, iron, lead, mercury, zinc, 

 and various organic contaminants. Potential contaminant 

 sources identified by MultiTech (1987a) include: 



buried tailings associated with the former Parrot 

 Smelter operations 



the Weed Concentrator complex 



tailings associated with the former Butte Reduction 

 Works 



the Anaconda Pole Treatment Facility site at 

 Rocker 



the Colorado Tailings 



Ramsay Flats mining wastes 



fluvially deposited mining wastes 



the Warm Springs Ponds 



the Metro Storm Drain 



Missoula Gulch and the lower portion of Browns 

 Gulch 



the Butte WWTP 



storm drain outfalls 



the Montana Post and Pole Treatment seep (a 

 separate Superfund site) .
