OBJECTIVE ; Identify the nature and extent of heavy metal 

 contamination in the Anaconda area, evaluate risks to public 

 health and the environment and present alternatives to 

 correct the problem. 



DURATION ; 1983 - 1987 



CURRENT STATUS ; The Anaconda Smelter and surrounding area, 

 including the Opportunity Treatment Ponds, was designated as 

 a Superfund site in December, 1982. Throughout 1983, the 

 Anaconda Minerals Company (AMC) and their consultants 

 conducted studies of contaminants at the site. In October, 

 1984, AMC agreed to carry out a complete Remedial Investiga- 

 tion/Feasibility Study (RI/FS) of the area with EPA. Sources, 

 pathways and the extent of heavy metal contamination will be 

 identified and alternative{s) for cleanup prescribed. 



Due to the complexity of the site, the final work plan 

 for the Anaconda Smelter RI/FS includes several "focused" 

 remedial investigations within the overall plan, including 

 studies of the beryllium disposal areas on Weather Hill and 

 at the B2 portion of the Opportunity Ponds, the granulated 

 slag pile, the flue dust disposal and/or storage areas, the
