Description Rainbow trout, mountain whitefish, and largescale suckers from the upper Spokane River were collected for PCB analysis in August 1996 to determine if concentrations had decreased from the levels seen in 1993-94. Samples were collected above Upriver Dam, above Monroe Street Dam, above Nine-Mile Dam, and in the Little Spokane River. In eight of the ten sample sets evaluated, mean PCB concentrations showed a consistent decrease from when first analyzed in 1993 or 1994. The decline in PCB concentrations was statistically significant in the four instances where there were sufficient data for testing.
