www.lsc.usgs.gov — This is a research project whose primary objective is to assess the health of selected fish species (brown bullhead and largemouth bass) and compare these findings with historic information on fish health in the individual rivers and with concurrent samples collected at reference sites. A secondary objective is to compare and correlate the fish More...

www.rsc.org — Environmental contaminant and biomarker monitoring data from major U.S. river basins were summarized for black bass (Micropterus spp.) and common carp (Cyprinus carpio) sampled over a nine year period. Cumulative frequency distributions revealed taxon differences for many organochlorine residue concentrations, elemental contaminant concentrations, More...

wfrc.usgs.gov — Mercury contamination from historic gold mining operations is widespread in many rivers, lakes, and reservoirs on the western slopes of the Sierra Nevada. A multidisciplinary investigation by USGS is attempting to better understand mercury dynamics and to identify hot spots within Camp Far West Reservoir in order to determine if remediation More...

tinyurl.com — Organochlorine pesticide and total polychlorinated biphenyl (PCB) concentrations were measured in largemouth bass from the Tombigbee River near a former DDT manufacturing facility at McIntosh, Alabama. Concentrations of DDT isomers in McIntosh bass remained unchanged from 1974 to 2004 and were four times greater than contemporary concentrations More...

wfrc.usgs.gov — Artificially maintained water levels within the lake and stresses placed upon the aquifer by well withdrawals facilitate movement of water from the lake into the local ground water system, potentially allowing contaminants to enter the aquifer from the lake. This raises national concern because similar lakeside settings exist throughout the United More...
