Salt Domes are mounds or columns of salt that have risen above their parent rock unit because of the salt’s low specific gravity.
They serve as oil and natural gas reservoirs; sources of sulfur; sources of salt; underground storage sites for oil, natural gas and helium; and, disposal sites for hazardous waste.
Wastewater Injection and Earthquakes|
March 27, 2013 | Columbia University
“Scientists have linked a rising number of quakes in normally calm parts of Arkansas, Texas, Ohio and Colorado to below-ground injection. In the last four years, the number of quakes in the middle of the United States jumped 11-fold from the three decades prior.” Quoted from the Columbia University press release.
Marcellus Shale Impact on Pennsylvania Waterways|
March 17, 2013 | PennLive.com
A study published in the Proceedings of the National Academies of Sciences reports that chemical spills associated with Marcellus Shale drilling have not significantly impacted Pennsylvania waterways.
NORM from the Marcellus Shale|
March 12, 2013 | Pennsylvania Department of Environmental Protection
“Drill cuttings and other materials associated with oil and gas have occasionally triggered radiation monitors at landfills. DEP’s data indicates that less than half a percent of all drill cuttings produced by the Marcellus Shale industry in 2012 that were disposed of in landfills triggered radiation monitors. The cuttings did not contain levels of radioactivity that would be harmful to the public, and they were safely disposed of in the landfills.” Quoted from the DEP announcement.
What is Killing the Coral?|
February 15, 2013 | National Science Foundation
Elkhorn coral and 65 other species of reef-building corals were recently proposed for “endangered species” designation. Researchers are working to understand why these corals are disappearing from the Florida Keys and other locations.
Finally a Use for Acid Mine Drainage Sludge?|
December 18, 2012 | USGS
“Dried acid mine drainage sludge, or residuals, that result from treating acid mine drainage discharges can be used as a low-cost adsorbent elsewhere to efficiently remove phosphorus from agricultural and municipal wastewaters.” Quoted from the USGS press release.

Injection Wells and Earthquakes|
April 23, 2012 | Bloomberg.com
An article on the Bloomberg.com website explains how some states are responding to the correlation between wastewater injection and shallow earthquake activity. Injection well disposal of hydraulic fracturing wastewater is declining rapidly as natural gas drilling operations are recycling more of their wastewater instead of sending it to injection wells.
Oklahoma Earthquake Position Statement|
April 11, 2012 | Oklahoma Geological Survey
The Oklahoma Geological Survey has published a “Position Statement on Triggered or Induced Seismicity” that was motivated by many people attributing recent earthquake activity to fluid injection.
USGS on Ohio Fluid Injection Well Earthquakes|
April 5, 2012 | USGS
“There is a credible connection between the wastewater injection activities near Youngstown and the recent earthquakes, including the magnitude 4 earthquake that occurred on New Year’s Eve, 2011. This connection is based on the close proximity of the earthquakes to the injection well and depth of injection, and the observation that these events began soon after the start of the injection activities.” Quoted from the USGS FAQ.
Growth in Wind and Biomass Energy|
February 29, 2012 | Energy Information Administration
The Energy Information Administration forecasts that United States non-hydro renewable power generation growth over the next 25 years will be led by gains in wind and biomass.
Evaluation of Geologic Carbon Dioxide Storage|
February 9, 2012 | USGS
“This methodology is designed to assess the storage resources in mappable subsurface bodies of rock into which CO2 is injected and trapped; in this methodology, these mappable subsurface bodies of rock are referred to as storage assessment units (SAUs). The total volume of pore space within a SAU can be described as the total in-place resource.” Quoted from the USGS report.
Nuclear Waste in Arizona Salt?|
January 15, 2012 | Arizona Geology
The Arizona Geology blog links to four articles related to the storage of high level nuclear waste in underground salt deposits.
Ohio Injection Well Temporarily Closed|
January 4, 2012 | The Columbus Dispatch
The Ohio Department of Natural Resources has temporarily shut down a waste injection well that is suspected to have triggered earthquakes. The state has nearly 200 other injection wells that have not been associated with seismic activity.
