Reinterpreting the importance of oxygen-based biodegradation in chloroethene-contaminated groundwater Reinterpreting the importance of oxygen-based biodegradation in chloroethene-contaminated groundwater
Chlororespiration is common in shallow aquifer systems under conditions nominally identified as anoxic. Consequently, chlororespiration is a key component of remediation at many chloroethene-contaminated sites. In some instances, limited accumulation of reductive dechlorination daughter products is interpreted as evidence that natural attenuation is not adequate for site remediation...

Hydrogeologic settings and groundwater-flow simulations for regional investigations of the transport of anthropogenic and natural contaminants to public-supply wells—Investigations begun in 2004 Hydrogeologic settings and groundwater-flow simulations for regional investigations of the transport of anthropogenic and natural contaminants to public-supply wells—Investigations begun in 2004
A study of the Transport of Anthropogenic and Natural Contaminants to public-supply wells (TANC study) was begun in 2001 as part of the U.S. Geological Survey National Water-Quality Assessment (NAWQA) Program. The study was designed to shed light on factors that affect the vulnerability of groundwater and, more specifically, water from public-supply wells to contamination to provide a...

Occurrence of antibiotic resistance and characterization of resistant genes and integrons in Enterobacteriaceae isolated from integrated fish farms south China Occurrence of antibiotic resistance and characterization of resistant genes and integrons in Enterobacteriaceae isolated from integrated fish farms south China
Antibiotics are still widely applied in animal husbandry to prevent diseases and used as feed additives to promote animal growth. This could result in antibiotic resistance to bacteria and antibiotic residues in animals. In this paper, Enterobacteriaceae isolated from four integrated fish farms in Zhongshan, South China were tested for antibiotic resistance, tetracycline resistance genes

Science Goals of the U.S. Department of the Interior Southeast Climate Science Center Science Goals of the U.S. Department of the Interior Southeast Climate Science Center
In 2011, the U.S. Department of the Interior Southeast Climate Science Center (CSC) finalized the first draft of its goals for research needed to address the needs of natural and cultural partners for climate science in the Southeastern United States. The science themes described in this draft plan were established to address the information needs of ecoregion conservation partnerships...

Mercury bioaccumulation and biomagnification in Ozark stream ecosystems Mercury bioaccumulation and biomagnification in Ozark stream ecosystems
Crayfish (Orconectes spp.), Asian clam (Corbicula fluminea), northern hog sucker (hog sucker; Hypentelium nigricans), and smallmouth bass (smallmouth; Micropterus dolomieu) from streams in southeastern Missouri (USA) were analyzed for total mercury (HgT) and for stable isotopes of carbon (δ13C), nitrogen (δ15N), and sulfur (δ34S) to discern Hg transfer pathways. HgT concentrations were...

Integrating science and resource management in Tampa Bay, Florida Integrating science and resource management in Tampa Bay, Florida
Tampa Bay is recognized internationally for its remarkable progress towards recovery since it was pronounced "dead" in the late 1970s. Due to significant efforts by local governments, industries and private citizens throughout the watershed, water clarity in Tampa Bay is now equal to what it was in 1950, when population in the watershed was less than one-quarter of what it is today...

Data from in situ Observations of Fish Traps Set by Fishermen in St. John Waters, U.S. Virgin Islands, 1992-94 Data from in situ Observations of Fish Traps Set by Fishermen in St. John Waters, U.S. Virgin Islands, 1992-94
In order to estimate (1) the trapping pressure within Virgin Islands National Park (VINP) waters, (2) the effect of fish traps on park marine resources (both fishes and habitats), and (3) the effectiveness of park regulations in protecting marine resources, traps set by fishers were visually observed and contents censused in situ in 1992, 1993, and 1994, around St. John (U.S. Virgin...

Groundwater conditions and studies in the Augusta–Richmond County area, Georgia, 2008–2009 Groundwater conditions and studies in the Augusta–Richmond County area, Georgia, 2008–2009
Groundwater studies and monitoring efforts conducted during 2008–2009, as part of the U.S. Geological Survey (USGS) Cooperative Water Program with the City of Augusta in Richmond County, Georgia, provided data for the effective management of local water resources. During 2008–2009 the USGS completed: (1) installation of three monitoring wells and the collection of lithologic and...

Reactive-transport modeling of iron diagenesis and associated organic carbon remineralization in a Florida (USA) subterranean estuary Reactive-transport modeling of iron diagenesis and associated organic carbon remineralization in a Florida (USA) subterranean estuary
Iron oxides are important terminal electron acceptors for organic carbon (OC) remineralization in subterranean estuaries, particularly where oxygen and nitrate concentrations are low. In Indian River Lagoon, Florida, USA, terrestrial Fe-oxides dissolve at the seaward edge of the seepage face and flow upward into overlying marine sediments where they precipitate as Fe-sulfides. The...

Organic compounds assessed in Chattahoochee River water used for public supply near Atlanta, Georgia, 2004-05 Organic compounds assessed in Chattahoochee River water used for public supply near Atlanta, Georgia, 2004-05
An investigation by the U.S. Geological Survey (USGS) National Water-Quality Assessment (NAWQA) Program characterized the occurrence of 266 organic compounds in source water and finished water from the Chattahoochee River, which is the main water-supply source for the Atlanta metropolitan area. Source water is stream water collected at a surface-water intake prior to water treatment, and...
