Biomonitoring in the Boulder River Watershed, Montana: Metal Concentrations in Biofilm and Macroinverebrates, and Relations with Macroinvertebrate Assemblage;Final rept

摘要

Portions of the Boulder River watershed, Montana, have contained elevated concentrations of arsenic, copper, lead, and zinc in water, sediment and biology. Measurements of concentrations in biofilm and macroinvertebrates were taken to monitor metals impacts in aquatic biology and make comparisons with previous investigations. Continued monitoring of metal concentrations in biofilm and macroinvertebrates along with assessments of aquatic habitat and macroinvertebrate assemblage will assist remediation efforts.
