Nine points on the Clark Fork River, Montana and 15 points on its major tributaries were surveyed to determine the mercury concentration in several fish species. There is no apparent connection between mercury concentrations in fish tissue and mining activity now occurring in Butte-Anaconda area. Neither is there any apparent connection between these concentrations and the large pulp mill 10 miles west of Missoula. There may be a relation to early-day placer mining activity (Flint Creek), but this is not free of doubt. It is likely that most of the observed levels of mercury in fish are due to slow insertion of mercury into natural waters by ordinary weathering processes of the minerals present in the countryside.
