Study says fracking fluids could contaminate Marcellus aquifers within “just a few years”

By Abraham Lustgarten / ProPublica

A new study has raised fresh concerns about the safety of gas drilling in the Marcellus Shale, concluding that fracking chemicals injected into the ground could migrate toward drinking water supplies far more quickly than experts have previously predicted.

More than 5,000 wells were drilled in the Marcellus between mid-2009 and mid-2010, according to the study, which was published in the journal Ground Water two weeks ago. Operators inject up to 4 million gallons of fluid, under more than 10,000 pounds of pressure, to drill and frack each well.

Scientists have theorized that impermeable layers of rock would keep the fluid, which contains benzene and other dangerous chemicals, safely locked nearly a mile below water supplies. This view of the earth’s underground geology is a cornerstone of the industry’s argument that fracking poses minimal threats to the environment.

But the study, using computer modeling, concluded that natural faults and fractures in the Marcellus, exacerbated by the effects of fracking itself, could allow chemicals to reach the surface in as little as “just a few years.”

“Simply put, [the rock layers] are not impermeable,” said the study’s author, Tom Myers, an independent hydrogeologist whose clients include the federal government and environmental groups.

“The Marcellus shale is being fracked into a very high permeability,” he said. “Fluids could move from most any injection process.”

The research for the study was paid for by Catskill Mountainkeeper and the Park Foundation, two upstate New York organizations that have opposed gas drilling and fracking in the Marcellus.

Much of the debate about the environmental risks of gas drilling has centered on the risk that spills could pollute surface water or that structural failures would cause wells to leak.

Though some scientists believed it was possible for fracking to contaminate underground water supplies, those risks have been considered secondary. The study in Ground Water is the first peer-reviewed research evaluating this possibility.

The study did not use sampling or case histories to assess contamination risks. Rather, it used software and computer modeling to predict how fracking fluids would move over time. The simulations sought to account for the natural fractures and faults in the underground rock formations and the effects of fracking.

The models predict that fracking will dramatically speed up the movement of chemicals injected into the ground. Fluids traveled distances within 100 years that would take tens of thousands of years under natural conditions. And when the models factored in the Marcellus’ natural faults and fractures, fluids could move 10 times as fast as that.

Where man-made fractures intersect with natural faults, or break out of the Marcellus layer into the stone layer above it, the study found, “contaminants could reach the surface areas in tens of years, or less.”

The study also concluded that the force that fracking exerts does not immediately let up when the process ends. It can take nearly a year to ease.

As a result, chemicals left underground are still being pushed away from the drill site long after drilling is finished. It can take five or six years before the natural balance of pressure in the underground system is fully restored, the study found.

Myers’ research focused exclusively on the Marcellus, but he said his findings may have broader relevance. Many regions where oil and gas is being drilled have more permeable underground environments than the one he analyzed, he said.

“One would have to say that the possible travel times for a similar thing in Arkansas or Northeast Texas is probably faster than what I’ve come up with,” Myers said.

USGS report finds that wastewater injection is likely responsible for increased rate of earthquakes

By Joe Romm / Think Progress

A U.S. Geological Survey (USGS) team has found that a sharp jump in earthquakes in America’s heartland appears to be linked to oil and natural gas drilling operations.

As hydraulic fracturing has exploded onto the scene, it has increasingly been connected to earthquakes. Some quakes may be caused by the original fracking — that is, by injecting a fluid mixture into the earth to release natural gas (or oil). More appear to be caused by reinjecting the resulting brine deep underground.

Last August, a USGS report examined a cluster of earthquakes in Oklahoma and reported:

Our analysis showed that shortly after hydraulic fracturing began small earthquakes started occurring, and more than 50 were identified, of which 43 were large enough to be located. Most of these earthquakes occurred within a 24 hour period after hydraulic fracturing operations had ceased.

In November, a British shale gas developer found it was “highly probable” its fracturing operations caused minor quakes.

Then last month, Ohio oil and gas regulators said “A dozen earthquakes in northeastern Ohio were almost certainly induced by injection of gas-drilling wastewater into the earth.”

Now, in a paper to be deliver at the annual meeting of the Seismological Society of America, the USGS notes that “a remarkable increase in the rate of [magnitude 3.0] and greater earthquakes is currently in progress” in the U.S. midcontinent. The abstract is online. EnergyWire reports (subs. req’d) some of the findings:

The study found that the frequency of earthquakes started rising in 2001 across a broad swath of the country between Alabama and Montana. In 2009, there were 50 earthquakes greater than magnitude-3.0, the abstract states, then 87 quakes in 2010. The 134 earthquakes in the zone last year is a sixfold increase over 20th century levels.

The surge in the last few years corresponds to a nationwide surge in shale drilling, which requires disposal of millions of gallons of wastewater for each well. According to the federal Energy Information Administration, shale gas production grew, on average, nearly 50 percent a year from 2006 to 2010.

The USGS scientists point out that “a naturally-occurring rate change of this magnitude is unprecedented outside of volcanic settings or in the absence of a main shock, of which there were neither in this region.” They conclude:

While the seismicity rate changes described here are almost certainly manmade, it remains to be determined how they are related to either changes in extraction methodologies or the rate of oil and gas production.

EnergyWire points out, “all of the potential causes they explore in the paper relate to drilling, or more specifically, deep underground injection of drilling waste.”

Last year, the Department of Energy set up a committee to examine the full range of environmental impacts of fracking. I testified to the members and, in addition to raising the issue about methane leakage and global warming, brought up the issue of earthquakes.

The committee said that they were indeed aware of this issue and ultimately the seven-member panel released a report of environmental guidelines for the natural gas industry, which included call on more research on “Understanding induced seismicity triggered by hydraulic fracturing and injection well disposal.”

It’s time go beyond mere research and start developing national standards to minimize these earthquakes.

Report finds that fracking fluids cause death and reproductive damage in animals

By Krishna Ramanujan

A new report has found dozens of cases of illness, death and reproductive issues in cows, horses, goats, llamas, chickens, dogs, cats, fish and other wildlife, and humans. It says these conditions could be the result of exposure to gas drilling operations.

Hydraulic fracturing, popularly called hydrofracking, is a process for extracting natural gas from shale using chemicals and water.

The paper’s authors, Robert Oswald, a professor of molecular medicine at Cornell’s College of Veterinary Medicine, and veterinarian Michelle Bamberger, DVM ’85, interviewed animal owners in six states — Colorado, Louisiana, New York, Ohio, Pennsylvania and Texas — and cited 24 cases where animals were potentially affected by gas drilling.

According to the study, recently published online and appearing soon in print, in New Solutions: A Journal of Environmental and Occupational Health Policy, making a direct link between death and illness is not possible due to incomplete testing, proprietary secrecy from gas drilling companies regarding the chemicals used in hydrofracking, and non-disclosure agreements that seal testimony and evidence when lawsuits are settled.

“We have a number of case studies — they don’t tell us about the prevalence of problems associated with hydraulic fracturing, but they do tell us how things can happen,” said Oswald.

Some of the case studies include:

  • In Louisiana, 17 cows died within an hour of direct exposure to hydraulic fracturing fluid. A necropsy report listed respiratory failure with circulatory collapse as the most likely cause of death.
  • A farmer separated his herd of cows into two groups: 60 were in a pasture with a creek where hydrofracking wastewater was allegedly dumped; 36 were in separate fields without creek access. Of the 60 cows exposed to the creek water, 21 died and 16 failed to produce calves the following spring. None of the 36 cows in separated fields had health problems, though one cow failed to breed in the spring.
  • Another farmer reported that 140 of his cows were exposed to hydrofracking fluid when wastewater impoundment was allegedly slit, and the fluid drained into a pasture and a pond. “These farmers saw workers slitting the liner to decrease the amount of liquid in the impoundment in order to refill it,” said Bamberger. “We have heard it now on several occasions.” Of the 140 cows, about 70 died, and there were high incidences of stillborn and stunted calves.

The authors note that the “most striking finding” of their study was how difficult it was to get solid information on the link between hydrofracking and health effects.

To provide better assessments of health impacts, the researchers recommend:

  • prohibiting nondisclosure agreements when public health is at stake;
  • increasing food safety testing and research, as the study documented that animals exposed to chemicals were not tested prior to slaughter, and little is known about the effects of hydrofracking chemicals on meat and dairy products;
  • improving the monitoring of routes of exposure, including in water, soil and air; and, most importantly,
  • fully testing the air, water, soil and animals prior to drilling and at regular intervals after drilling is completed, and disclosing fully the chemicals used when hydrofracking.

“Without knowledge of all the chemicals being used, you can’t test before drilling,” said Bamberger. “And if we don’t have predrilling tests then if you find a chemical postdrilling, how can you prove that” it came from hydrofracking, she added.

Nuclear plants in United States experienced fifteen “near-misses” in 2011

By Environment News Service

The Union of Concerned Scientists has documented 15 “near-misses” at 13 U.S. nuclear plants during 2011 and evaluates the response of the Nuclear Regulatory Commission to each event in a report released today.

The second in an annual series of reports, “The NRC and Nuclear Power Plant Safety 2011 Report: Living on Borrowed Time” details 15 special inspections launched by the federal agency in response to problems with safety equipment, security shortcomings, and other troubling events at nuclear power plants.

The overview is provided by David Lochbaum, the director of UCS’s Nuclear Safety Project. He worked at U.S. nuclear plants for 17 years and was a boiling water reactor technology instructor for the Nuclear Regulatory Commission.

“While none of the safety problems in 2011 caused harm to plant employees or the public, their frequency – more than one per month – is high for a mature industry,” Lochbaum writes.

In the 40 years that the Union of Concerned Scientists has evaluated safety at U.S. nuclear power plants, “We have repeatedly found that NRC enforcement of safety regulations is not timely, consistent or effective,” the report states.

The UCS says its findings match those of the agency’s internal assessments, as well as of independent agents such as the NRC’s Office of Inspector General and the federal Government Accountability Office, which is the investigative arm of Congress.

Many of these 15 “near misses” occurred because reactor owners either tolerated known safety problems or took inadequate measures to correct them, Lochbaum finds.

For example, the owner of the Oconee nuclear plant in South Carolina installed a backup reactor core cooling system in 1983. However, in 2011 – more than a quarter-century later – workers discovered a problem with the system that would have rendered it useless in an accident.

Another significant safety-related event in 2011 occurred at the Braidwood and Byron nuclear plants in Illinois. Workers at those plants had instituted a practice in 1993 of deliberately draining water from the piping to a vital safety system. They did so to reduce corrosion caused by the drawing of untreated lake water into the system. However, writes Lochbaum, “their solution would have prevented this vital safety system from functioning properly during an accident.”

In addition to “near misses” at these three nuclear plants, 12 others are documented in the report.

  • At Callaway in Jefferson City, Missouri, operated by Union Electric Co., routine testing of an emergency pump intended to prove that it was capable of performing its safety functions during an accident actually degraded the pump. The pump’s manufacturer recommended against running the pump at low speeds, but this recommendation was ignored during the tests.
  • At Cooper in Nebraska City, Nebraska, operated by the Nebraska Public Power District, workers replacing detectors used to monitor the reactor core during low-power conditions were exposed to high levels of radiation when they deviated from the prescribed procedure.
  • At Millstone Unit 2 in Waterford, Connecticut, operated by Dominion, despite a dry run of an infrequently performed test on the control room simulator and other precautionary measures, errors during the actual test produced an unexpected and uncontrolled increase in the reactor’s power level.
  • At North Anna in Richmond, Virginia, operated by Dominion, an earthquake of greater magnitude than the plant was designed to withstand caused both reactors to automatically shut down from full power.
  • At Palisades in South Haven, Michigan, operated by Entergy, when a pump used to provide cooling water to emergency equipment failed in September 2009 because of stress corrosion cracking of recently installed parts, workers replaced the parts with identical parts. The replacement parts failed again in 2011, disabling one of three pumps.
  • Also at Palisades, workers troubleshooting faulty indicator lights showing the position of the emergency airlock door inadvertently shut off power to roughly half the instruments and controls in the main control room. The loss of control power triggered the automatic shutdown of the reactor and complicated operators’ response.
  • At Perry in Cleveland, Ohio, operated by FirstEnergy, problems during the replacement of a detector used to monitor the reactor core during low-power conditions exposed workers to potentially high levels of radiation.
  • At Pilgrim in Plymouth, Massachusetts, operated by Entergy, security problems prompted the NRC to conduct a special inspection. Details of the problems, their causes, and their fixes are not publicly available.
  • Also at Pilgrim, when restarting the reactor after a refueling outage, workers overreacted to indications that the water inside the reactor was heating up too rapidly, and lost control of the reactor. The plant’s safety systems automatically kicked in to shut down the reactor.
  • At Turkey Point Unit 3 in Miami, Florida, operated by Florida Power and Light Co., a valve failure stopped the flow of cooling water to equipment, including the reactor coolant pump motors and the cooling system for the spent fuel pool.
  • At Wolf Creek in Burlington, Kansas, operated by the Wolf Creek Nuclear Operating Co., workers overlooked numerous signs that gas had leaked into the piping of safety systems, impairing the performance of pumps and flow-control valves.

The report also cites instances when onsite NRC inspectors made “outstanding catches of safety problems” at the Fort Calhoun, Hatch, and LaSalle nuclear plants before these impairments led to events that required special inspections, or to major accidents.

Anti-Fracking Campaigners: We Won’t Be Silenced

Anti-Fracking Campaigners: We Won’t Be Silenced

Anti-Fracking Campaigners: We Won’t Be Silenced

Gasland was intended to be both a chronicle of the way in which oil and gas companies have used vast sums of money to shield fracking from virtually all federal, state, and local regulations and a cautionary tale about the toll the process takes on people and the environment.

Fortunately, the message of the film is getting through. Recent surveys show that 4 out of 5 Americans are concerned about fracking’s effect on our drinking water and seven out of ten Ohioans believe the process should be stopped until we know more about its effect on the environment and its relation to a series of earthquakes that have rocked the Northeastern part of the state.

The bottom line: fracking is not safe. It has never been proven safe and it will never be made safe. The industry admits that well casing problems occur in 50 percent of wells over the life of the well. That means that 50 percent of gas wells can be expected to leak chemicals, hydrocarbons, volatile organic compounds, carcinogens and neurotoxins directly into groundwater. The industry has never been able to solve this problem although they have been trying for decades and they have admitted that there is no solution to the problem. Safe fracking is simply an impossibility. If the state allows further drilling, it is trading water for gas. It is trading the short-term windfall profits of huge gas companies for our public health and the permanent poisoning of our ground water.

Unfortunately, Governor John Kasich and the Republican majority in the Ohio General Assembly, like so many members of Congress and officials in other states, have decided to listen to the siren song of the industry rather than the concerns of their constituents and the growing body of scientific research that is shining a brighter and brighter spotlight on the dangers of fracking. It’s no accident that the governor is delivering his State of the State address in the hotbed of fracking in Ohio.

He’ll undoubtedly praise the industry and the jobs it promises to create in an attempt to divert attention from the fact that those jobs come at a steep cost to the environment and public health.

He won’t mention that as he is speaking in Steubenville on Tuesday or the five bills designed to address environmental and health concerns related to fracking that are languishing in the Ohio House and Senate in Columbus because the industry does not want them to be heard.

He won’t mention that oil and gas producers now pay state taxes on the “honor system.” As unbelievable as it may seem, the industry tells the state how much gas they’ve extracted and pays taxes based on that figure. There’s no oversight or monitoring. In fact, the state lacks the authority to check meters at the wellhead and compare those readings against the figures turned in by producers. The producers pay what they want to pay—no questions asked.

That’s an especially troubling thought when you consider that this industry is totally devoid of anything that even approaches honor—and that their tax liability could climb to as much as $40 million per year if they do all the fracking they want to do—and then accurately self-report the volume of gas they extract. Given their history, I think we can count on the former and forget about the latter.

The aversion to regulation and the truth about fracking in Ohio is nothing new. This is an industry built on secret deals, influence peddling and media manipulation. It is grounded on the exemptions from the Clean Air Act, Clean Water Act, and Superfund Act and, crucially to the Safe Drinking Water Act, from which fracking was exempted by Congress in 2005. It is fueled by the near universal desperation for jobs and economic development that exists in the regions where most fracking occurs.

Thankfully, however, the public is slowly but surely digging itself out from underneath the mounds of industry propaganda that has enabled them to punch tens of thousands of holes in the Earth without adequate oversight. The earthquakes that shook Northeast Ohio did more than scare residents, it raised very real questions about the process and its long term effects that people want answered, NOW.

I applaud the public officials and the environmental, public health, and community groups, and the thousands of concerned residents who are demanding answers from the industry and the elected officials who do their bidding. I urge you to continue the fight, to keep asking the hard questions—even if it means being arrested for seeking the truth as I was last week for merely attempting to record a public hearing in the U.S. House of Representatives.

Send this message to the industry and the politicians they control: we won’t be silenced. We can’t be bought. We will fight to keep our families and our communities safe.
