Speciation and Fate of Arsenic in Three Lakes of the Aberjona Watershed
The speciation of arsenic in the environment is controlled by reduction, methylation, and oxidation processes and is therefore influenced by redox conditions. However, in the... -
CHEMISTRY AND ORIGIN OF OIL AND GAS WELL BRINES IN WESTERN PENNSYLVANIA
Brines having moderate to high salt content (up to 343 grams per liter [g/L]) occupy most pore spaces in rocks below a depth of a few thousand feet in Pennsylvania and are... -
Probing Influence of Reactions between Fracture Fluids and Marcellus Shale
In this study we investigated Marcellus Shale metal extractability, and reactivity with fracturing fluids, through bulk extractions and experiments in high-pressure,... -

Radium activity data for waters co-produced with oil and gas in New York and Pennsylvania have been compiled from publicly available sources and are presented together with new... -
Methane in West Virginia Ground Water
Methane has been found as a dissolved gas in numerous ground-water samples from water wells in West Virginia. Methane (CH4) is a colorless, odorless, tasteless gas that can... -
Dissolved Methane in New York Groundwater
New York State is underlain by numerous bedrock formations of Cambrian to Devonian age that produce natural gas and to a lesser extent oil. This USGS Open-File report examines... -
