The response of treatment in reducing leachate quantity and 

 abating metal movement to surface and ground water will also 

 be evaluated (CH2M Hill 1987c) . Siting and construction of 

 the field demonstration are ongoing and it is anticipated 

 that the plots will be seeded in late fall 1988. If the fall 

 planting season is missed, the plots will be seeded in the 

 spring of 1989. The plots will be monitored through two 

 field seasons, with a final Phase II report due sometime in 

 1991. 



Clark Fork Reclamation Demonstration Project 



In September 1986, a proposal for an upper Clark Fork 

 floodplain reclamation demonstration project was submitted to 

 the DNRC for funding under the Resource Indemnity Trust (RIT) 

 Grants Program. The proposal was prepared and submitted by 

 the Governor's Office Clark Fork Basin Project, the Head- 

 waters RC&D, and the Deer Lodge County Conservation District. 

 The purpose of the project was to evaluate the cost and 

 effectiveness of a variety of reclamation techniques applied 

 to an entire floodplain segment (streambanks, riparian area, 

 and adjacent agricultural lands) of the upper Clark Fork. 

 The project was approved for RIT funding in 1987; however, 

 funds were not available until late 1988. It is anticipated 

 that work will begin in 1989. 



Some preliminary work was conducted on the project in 

 the fall of 1987. With help from a Deer Lodge/Powell County 

 Soil Conservation Service (SCS) Soil Survey party, Schafer 

 and Associates (1988) conducted a detailed survey of the 

 study area under contract with the Governor's Office. 



The objectives of the investigation were to: 



• determine the source, extent, and severity of 

 tailings contamination in the study area 



• determine where and under what conditions metals 

 from streamside tailings may be entering the Clark 

 Fork 



• identify potential low-cost remedial measures to 

 reduce or eliminate the movement of contaminants 

 into the river 



• propose specific candidate sites for a remedial 

 demonstration.
