Michelle Hornberger, PhD
Michelle Hornberger is a research physical scientist at the U.S. Geological Survey, focusing on identifying the ecological consequence of chemical and physical disturbance in aquatic systems. Benthic macroinvertebrates are used as bioindicators of environmental condition in watersheds impacted by multiple stressors, including hard rock mining and wildfires.

Linkage of bioaccumulation and biological effects to changes in pollutant loads in south San Francisco Bay Linkage of bioaccumulation and biological effects to changes in pollutant loads in south San Francisco Bay
The developed world has invested billions of dollars in waste treatment since the 1970s; however, changes in ecological or biological responses are rarely associated with reductions in metal pollutants. Here we present a novel, 23-yr time series of environmental change from a San Francisco Bay mudflat located 1 km from the discharge of a suburban domestic sewage treatment plant. Samples...

Surface-water-quality assessment of the Yakima River basin in Washington: Spatial and temporal distribution of trace elements in water, sediment, and aquatic biota, 1987-91 Surface-water-quality assessment of the Yakima River basin in Washington: Spatial and temporal distribution of trace elements in water, sediment, and aquatic biota, 1987-91
The report describes the distribution of trace elements in sediment, water, and aquatic biota in the Yakima River basin, Washington. Trace elements were determined from streambed sediment, suspended sediment, filtered and unfiltered water samples, aquatic insects, clams, fish livers, and fish fillets between 1987 and 1991. The distribution of trace elements in these media was related to...

Historical trends of metals in the sediments of San Francisco Bay, California Historical trends of metals in the sediments of San Francisco Bay, California
Concentrations of Ag, Al, Cr, Cu, Fe, Hg, Mn, Ni, Pb, V and Zn were determined in six sediment cores from San Francisco Bay (SFB) and one sediment core in Tomales Bay (TB), a reference estuary. SFB cores were collected from between the head of the estuary and its mouth (Grizzly Bay, GB; San Pablo Bay, SP; Central Bay, CB; Richardson Bay, RB, respectively) and ranged in length from 150 to...

Water, bed sediment, and biota were sampled in streams from Butte to below Missoula as part of a program to characterize aquatic resources in the upper Clark Fork basin of western Montana. Sampling stations were located on the Clark Fork and major tributaries. Water-quality data were obtained periodically at 16 stations during October 1994 through September 1995 (water year 1995). Data...
