Data on the Effects of Oil and Gas Wastewater Components on Microbial Community Structure and Function Data on the Effects of Oil and Gas Wastewater Components on Microbial Community Structure and Function
Oil and gas (OG) wastewaters are commonly disposed of by underground injection and previous research showed that activities at a disposal facility in West Virginia affected stream biogeochemistry and sediment microbial communities downstream from the facility. Microorganisms can control the fate and transport of organic and inorganic components of OG wastewater highlighting the need to
Chemistry Data from Southern Florida Canals Collected in Support of the Aquatic Cycling of Mercury in the Everglades Project Chemistry Data from Southern Florida Canals Collected in Support of the Aquatic Cycling of Mercury in the Everglades Project
Several canals in southern Florida run from Lake Okeechobee through the Everglades Agricultural Area (EAA) and feed water to the northern Everglades. Agricultural and water-management practices affect the water quality of these canals. Fertilizers added in the EAA flow into the canals and are transported to treatment areas which remove much of the phosphorous in the water, but are not as...
Organic Analysis of Oilfield Wastewater from the Williston Basin, North Dakota Organic Analysis of Oilfield Wastewater from the Williston Basin, North Dakota
The organic composition of produced waters (flowback and formation waters) from the Bakken Formation and the Three Forks Formation in the Williston Basin, North Dakota were examined in this study in order to aid in the remediation of surface contamination due to spills during transport and help develop treatment methods for recycling. Twelve produced water samples were collected from...
DDT and related compounds in pore water of shallow sediments on the Palos Verdes Shelf, CA DDT and related compounds in pore water of shallow sediments on the Palos Verdes Shelf, CA
For nearly two and a half decades following World War II, production wastes from the worlds largest manufacturer of technical DDT were discharged into sewers of Los Angeles County. Following treatment, the wastes were released via a submarine outfall system to nearshore coastal waters where a portion accumulated in shallow sediments of the Palos Verdes Shelf (PVS). An investigation of...
Stratigraphic, geochemical, and hydrologic data for the Boston Peak wetland, Larimer County, CO, USA Stratigraphic, geochemical, and hydrologic data for the Boston Peak wetland, Larimer County, CO, USA
Comprehensive sampling of peat, underlying lakebed sediments, and coexisting waters of a naturally uraniferous montane wetland are combined with hydrologic measurements to define the important controls on uranium (U) supply and uptake. The major source of U to the wetland is groundwater flowing through locally fractured and faulted granite gneiss of Proterozoic age. Dissolved U...

Origin and geochemistry of formation waters from the lower Eagle Ford Group, Gulf Coast Basin, south central Texas Origin and geochemistry of formation waters from the lower Eagle Ford Group, Gulf Coast Basin, south central Texas
The lower Eagle Ford Group (LEFG) is one of the most productive continuous hydrocarbon plays in the United States but few associated produced waters data and minimal interpretation have been published. This effort focuses on results from compositional and isotopic data from 39 produced water samples collected from horizontal wells producing from the LEFG in south central Texas. The depth...

Organic compounds in produced waters from the Bakken Formation and Three Forks Formation in the Williston Basin, North Dakota Organic compounds in produced waters from the Bakken Formation and Three Forks Formation in the Williston Basin, North Dakota
The organic composition of produced waters (flowback and formation waters) from the middle member of the Bakken Formation and the Three Forks Formation in the Williston Basin, North Dakota were examined to aid in the remediation of surface contamination and help develop treatment methods for produced-water recycling. Twelve produced water samples were collected from the Bakken and Three...

Review of studies of composition, toxicology and human health impacts of wastewater from unconventional oil and gas development from shale Review of studies of composition, toxicology and human health impacts of wastewater from unconventional oil and gas development from shale
Unconventional oil and gas (UOG) extractions has produced large economic benefits. However, prudent management of UOG wastes necessitates a thorough understanding of the complex composition, fate, and potential impacts of wastewater releases. UOG production results in large volumes of wastewater. Despite limited re-use of the wastewater, the majority needs to be disposed of, usually by...

Coal biomethanation potential of various ranks from Pakistan: A possible alternative energy source Coal biomethanation potential of various ranks from Pakistan: A possible alternative energy source
The present study investigated the possibility of microbial transformations of coal to gas (biogasification) as an alternative to conventional coal mining because this approach has the potential to be less expensive, cleaner, and providinge greater access to deeper coal resources. Biogasification is often associated with low rank coal such as lignite and subbituminous coal that hasve...

Aquatic cycling of mercury Aquatic cycling of mercury
This chapter examines crucial processes in the aquatic cycling of mercury (Hg) that may lead to microbial production of neurotoxic and bioaccumulative methylmercury (MeHg), and highlights environmental conditions in the Everglades that make it ideal for MeHg production and bioaccumulation. The role of complexation of Hg2+ in surface water, especially by dissolved organic matter (DOM), in...

Sulfur contamination in the Everglades, a major control on mercury methylation Sulfur contamination in the Everglades, a major control on mercury methylation
In this chapter sulfur contamination of the Everglades and its role as a major control on methylmercury (MeHg) production is examined. Sulfate concentrations over large portions of the Everglades (60% of the ecosystem) are elevated or greatly elevated compared to background conditions of
