The Four Corners area (red) is the major U.S. hot spot for methane emissions in this map showing how much emissions varied from average background concentrations from 2003-2009 (dark colors are lower than average; lighter colors are higher).

FRISCO — The Four Corners region is a methane hotspot, producing the largest concentration of the heat-trapping greenhouse gas methane seen over the United States. Atmospheric concentrations of the gas are more than three times the standard ground-based estimate, according to a new study of satellite data by scientists at NASA and the University of Michigan.

Central Valley groundwater tainted by illegal injections of oil and gas industry wastewater
By Summit Voice
FRISCO — All those warm-n-fuzzy fossil fuel industry ads showing clean-cut techs in lab coats with clipboards may play well on your plasma screen, but reality is a little different.
Rather than being upstanding corporate citizens looking out for the country’s best interests, some energy companies operating in California have been illegally injecting huge quantities of oil and gas wastewater into central California aquifers that supply drinking water and farming irrigation.

Methane emissions: up, up … up.
EPA report shows the greenhouse gas dragon is far from tamed
FRISCO — The EPA may be putting lipstick on the methane pig by claiming that methane emissions dropped during the past year, according to watchdog groups who say the numbers put forth by the federal agency are misleading.
Overall, the EPA reported Sept. 30 that greenhouse gas emissions from large industrial facilities climbed by 20 million metric tons in 2013, up 0.6 percent from the previous year. Continue reading

Oil and gas drillers must to more to protect the airsheds they operate in.
Air quality worsening in rural areas affected by fracking
FRISCO — Dangerously high levels of winter ozone pollution in parts of Utah can be traced directly to chemicals released into the air by oil and gas exploration. The volatile organic compounds, common byproducts of fossil fuel exploitation, get trapped under atmospheric inversion layers and sunlight reflected by snow sparks the chemical process that forms the corrosive gas.
For example, in 2013, ozone in Ouray, Utah, exceeded the national air quality standards 49 times during the winter season. By contrast, in the densely populated, urban area of Riverside, California, the standards were exceeded about half that amount that same year, but during the summer. Continue reading

U.S. Geological Survey researchers have linked a surge in earthquakes in southern Colorado and northern New Mexico with injection of fracking wastewater.
Scientists say it’s almost certain that massive injections of waste water caused recent quakes in the Raton Basin, including a 5.3 tremor in 2011
FRISCO — A surge in earthquakes in southern Colorado and New Mexico has almost certainly been caused by the injection of fracking wastewater deep into the ground, U.S. Geological Survey scientists reported last week.
The study details several lines of evidence directly linking the injection wells to the seismicity. The timing and location of the quakes is clearly linked with the the documented pattern of injected wastewater.
Detailed investigations of two seismic sequences (2001 and 2011) places them in proximity to high-volume, high-injection-rate wells, and both sequences occurred after a nearby increase in the rate of injection. A comparison between seismicity and wastewater injection in Colorado and New Mexico reveals similar patterns, suggesting seismicity is initiated shortly after an increase in injection rates.
For example, two injection wells near the epicenter of a 2011 5.3 earthquake had about 5 million cubic meters of wastewater injected just before the quake — more than seven times the amount injected at the Rocky Mountain Arsenal well that caused damaging earthquakes near Denver, Colorado, in the 1960s. The August 2011 M 5.3 event is the second-largest earthquake to date for which there is clear evidence that the earthquake sequence was induced by fluid injection.

Oklahoma earthquake spike definitively linked with wastewater injection.
More monitoring and mitigation needed, scientists say
By Summit Voice
FRISCO — Just a small number of wastewater injection wells associated with fossil fuel exploitation can lead to a dramatic increase in earthquakes, U.S. Geological Survey scientists concluded in a new study focusing on the spike in Oklahoma earthquakes since 2009. Wastewater injection can trigger earthquakes up to 20 miles away, the researchers found, far beyond the three-mile radius commonly used as a measure for diagnosing induced earthquakes.
The dramatic increase in earthquakes in central Oklahoma since 2009 is likely attributable to subsurface wastewater injection at just a handful of disposal wells. Oklahoma earthquakes constitute nearly half of all central and eastern U.S. seismicity from 2008 to 2013, many occurring in areas of high-rate water disposal, said Cornell University geophysics professor Katie Keranen, who led the study.

Oklahoma earthquakes are on the increase.
Spike in tremors linked with injection of wastewater from fracking
By Summit Voice
FRISCO — Federal and state geologists say there’s an increased risk of a strong earthquake in Oklahoma after the overall rate of quakes increased by about 50 percent since late 2013.
After statistically analyzing the increased rate of earthquakes, the scientists said they’re fairly certain it’s not just natural variability — deep injection of waste water from fossil fuel exploitation is seen as a likely cause. Continue reading
