Assessment of groundwater input and water quality changes impacting natural vegetation in the Loxahatchee River and floodplain ecosystem, Florida Assessment of groundwater input and water quality changes impacting natural vegetation in the Loxahatchee River and floodplain ecosystem, Florida
The Loxahatchee River and Estuary are small, shallow, water bodies located in southeastern Florida. Historically, the Northwest Branch (Fork) of the Loxahatchee River was primarily a freshwater system. In 1947, the river inlet at Jupiter was dredged for navigation and has remained permanently open since that time. Drainage patterns within the basin have also been altered significantly...

Organic geochemistry of sediments in nearshore areas of the Mississippi and Atchafalaya Rivers: I. General organic characterization Organic geochemistry of sediments in nearshore areas of the Mississippi and Atchafalaya Rivers: I. General organic characterization
This report presents results on the general organic characteristics of sediment cores collected from the coastal zone of the Mississippi River system, including distributions of the important nutrient elements (C, N, P, and S). This was part of a larger study conducted from 2001-2005 to examine the delivery of sediment-associated contaminants to the Gulf of Mexico by the Mississippi...

Evaluating nephrotoxicity of high-molecular-weight organic compounds in drinking water from lignite aquifers Evaluating nephrotoxicity of high-molecular-weight organic compounds in drinking water from lignite aquifers
High-molecular-weight organic compounds such as humic acids and/or fulvic acids that are naturally mobilized from lignite beds into untreated drinking-water supplies were suggested as one possible cause of Balkan endemic nephropathy (BEN) and cancer of the renal pelvis. A lab investigation was undertaken in order to assess the nephrotoxic potential of such organic compounds using an in...

Lateral variation in geochemistry, petrology, and palynology in the Elswick coal bed, Pike County, Kentucky Lateral variation in geochemistry, petrology, and palynology in the Elswick coal bed, Pike County, Kentucky
The Middle Pennsylvanian/Langsettian (Westphalian A) Elswick coal bed, correlative to the Upper Banner of Virginia, is a rare example of a mined high-sulfur (> 2%) coal in Eastern Kentucky, a region known for low-sulfur coals. To characterize lateral variation in the geochemistry, petrography, and palynology of the Elswick coal bed, three sites were sampled along a southeast-northwest...

Organic compounds in produced waters from coalbed natural gas wells in the Powder River Basin, Wyoming, USA Organic compounds in produced waters from coalbed natural gas wells in the Powder River Basin, Wyoming, USA
The organic composition of produced water samples from coalbed natural gas (CBNG) wells in the Powder River Basin, WY, sampled in 2001 and 2002 are reported as part of a larger study of the potential health and environmental effects of organic compounds derived from coal. The quality of CBNG produced waters is a potential environmental concern and disposal problem for CBNG producers, and...

Sulfur contamination in the Florida Everglades: Initial examination of mitigation strategies Sulfur contamination in the Florida Everglades: Initial examination of mitigation strategies
Introduction Sulfate contamination of the Everglades is a serious water quality issue facing restoration of this ecosystem. Sulfate concentrations in some marsh areas are more than 60 times background concentrations, and sulfate in excess of background levels covers an estimated 60% of the freshwater Everglades (Orem et al., 1997; Stober et al., 1996 and 2001; Orem et al., 2004). The...
