Pavillion-area citizens, landowners and environmental groups today condemned Gov. Mead’s (R-WY) announcement that the state is assuming control from the U.S. Environmental Protection Agency (EPA) of the investigation into groundwater contamination by fracking-enabled oil and gas development near Pavillion, WY.
In the announcement, the Governor congratulated EPA and Encana—the company operating in the Pavillion area—for working with him to “chart a positive course” for the investigation.
“We went to the EPA for help after the State of Wyoming and Encana refused to address the public health impacts of unbridled development in the Pavillion area," said Pavillion farmer John Fenton. "Now Encana has bought its way back in and is working with the state on a strategy to cover up the mess they’ve created."
"Our government’s priority is clearly to protect industry rather than Wyoming citizens, our health and our property values. Gov. Mead, the Obama administration and Encana have decided what is best for our community without consulting us,” Fenton continued. “We were presented with Mead’s vague plan at the same time it was released to the public. Unlike the other stakeholders, we bear the brunt of living in the toxic mess that has become our community, but our input has been thrown out with EPA’s investigation. This is a sad day for our country.”
This decision continues a nationwide pattern of Obama Administration walkbacks of the EPA investigations whose preliminary results indicate fracking-enabled oil and gas development presents real risks to public health and water. Similar actions have occurred in Parker County, TX, and Dimock, PA.
“It seems clear that the White House’s 'all of the above' energy policy means fracking’s impacts on communities are being ignored,” said Earthworks' energy program director Bruce Baizel. “All across the country, whether it’s Wyoming, or Texas or Pennsylvania, it appears the EPA is being politically pressured to back off sound science that shows fracking-enabled oil and gas development is a risk to public health. With these decisions, the Obama administration is creating more opposition to fracking, not less.”
“Gov. Mead said earlier this week that change should be driven by elected officials and agencies, not the people,” said Don Nelson, a farmer and rancher near Keene in western North Dakota, on behalf of the Western Organization of Resource Councils.
“This attitude is exactly why those of us who have to live with drilling and fracking have so little confidence in our regulatory agencies and elected officials. They only listen to the oil and gas industry, not to the local people. The same is true in North Dakota. And now EPA is backing down too and another investigation into groundwater contamination from oil and gas development is being swept under the rug. Why would anyone believe the oil and gas industry or the state regulatory agencies when they say drilling and fracking are safe?”
Governor Mead’s announcement indicates that the state would cease peer review of EPA’s investigation, essentially ignoring it.
“The state of Wyoming is already on record, through action and inaction, as denying that Pavillion’s groundwater contamination is a cause for concern,” said area ag-producer Jeff Locker. “They are throwing out a conscientious science based study by EPA that cost the taxpayers millions of dollars. The Governor’s plan postpones any conclusions for at least another year. It’s hard to believe that they’re trying to get to the bottom of the problem, they’re hoping this whole thing just goes away.”

The U.S. Geological Survey (USGS) has warned New York state regulators that their plan to allow drilling and hydraulic fracturing for natural gas in the Marcellus Shale could endanger private water wells, municipal aquifers and New York City’s drinking water supply.
The assessment of the USGS, widely regarded as impartial and authoritative on drilling issues, intensifies pressure on Gov. Andrew Cuomo (D-NY) not to proceed with a drilling plan drafted by the New York State Department of Environmental Conservation. Cuomo has pledged to “let the science and the facts make the determination, not emotion and not politics.”1
The U.S. Environmental Protection Agency (EPA) has separately written New York regulators arguing that they are ill-equipped to regulate a boom in shale gas drilling and have limited financial means to enforce the numerous new regulations they have proposed. The EPA has raised additional concerns, among them, that the state has understated the severity of radioactive pollution associated with drilling and doesn’t know how such contaminants would be disposed of.
Officials at the Department of Environmental Conservation are now considering whether to modify their plan to address the federal agencies’ reservations and about 60,000 letters from local governments, independent scientists, gas drillers, property owners, environmental groups and other interested citizens. Once the state agency has concluded its review, which could wind up as soon as this spring, the issue goes to Cuomo’s desk.
The stakes for New York taxpayers are enormous. The Department of Environmental Conservation has estimated that if New York City’s drinking water supply is contaminated by drilling, cleaning up the water would require a water filtration plant costing at least $8 billion, with a yearly operating expense of $200 million.2 Even then, city officials have said there is no guarantee that the water could be purified. If water supplies of other population centers are tainted, the cleanup costs would soar higher.
As now written, the state plan projects that tens of thousands of natural gas wells could spring up along the New York portion of the Marcellus Shale, a vast underground formation that stretches along the Appalachian chain as far south as Kentucky. Most of the wells are likely to deploy a relatively new shale-drilling process called high volume hydraulic fracturing and horizontal drilling, which typically involves injecting millions of gallons of water laced with chemicals into the ground under high pressure, aiming to crack shale rock and release natural gas trapped in small pockets.
The USGS, the federal government’s expert on the geology and hydrology of oil and gas drilling, advised New York regulators that their plan is flawed in several respects. Among them:
- The state’s proposal to prohibit drilling inside a 500-foot buffer around aquifers that supply major municipal water systems “is one-size-fits-all and may provide only partial protection to these aquifers.”3
- A similar 500-foot buffer for private water wells and springs “affords limited protection” and “does not take local geohydrologic conditions and topographic setting into account.” The USGS added that “changes brought about by drilling, including water quality changes, can be felt rapidly at significant distance from a disturbance—especially if a domestic well is [downhill] of a well pad.”4
- Pressurized fracturing fluids could migrate through underground faults and impact an underground aqueduct that carries drinking water to New York City. The USGS said that “the possibility of damage to the aqueduct from hydraulic-fracturing operations is an issue of concern” and deserves more study.5
- A map displayed in the state’s draft plan “grossly under-represents the number and extent of [natural] faults in the Appalachian Basin of New York” where shale gas drilling would occur. Ground that is riddled with underground faults could channel pollution from drilling into underground aquifers.6
- “Only scattered and incomplete information is available” on underground freshwater sources that could be polluted by shale gas drilling. The USGS said the state plan should require drilling companies to maintain detailed logs that would identify and protect these aquifers.7
Drilling too close to water sources
The USGS went to some lengths to dispute the state agency’s premise that drilling could be safely conducted 500 feet from water supplies. The federal agency said that in some cases, it might be necessary to prohibit drilling within five square miles of aquifers to avoid polluting them.8
The USGS position is bolstered by documented cases in Colorado, Ohio and Pennsylvania, where natural gas and related contaminants have polluted underground water supplies at distances much greater than 500 feet.
- In 2004, Canada-based Encana Corp. improperly cemented and hydraulically fractured a well in Garfield County, Colo. The state found that the poor cementing caused natural gas and associated contaminants to travel underground more than 4,000 feet laterally. As a result, a creek became contaminated with dangerous levels of carcinogenic benzene. The state of Colorado fined Encana a then-record $371,200. Despite more than seven years of cleanup efforts, as of last September, three groundwater monitoring wells near the creek still showed unsafe levels of benzene.9
- In 2007, a natural gas well fractured by Ohio Valley Energy Systems Corp. in Bainbridge, Ohio, caused natural gas to contaminate 23 nearby water wells, two of which were more than 2,300 feet from the drilling site.10
- In 2009, several natural gas wells drilled by Houston-based Cabot Oil and Gas Corp. in Dimock, Penn., polluted water wells used by at least 19 families, according to the state Department of Environmental Protection. Cabot has disputed the finding. At least three of the water wells were farther than 1,000 feet from the gas wells. For about two years, the Pennsylvania DEP ordered the company to deliver water to the families. Last December, Cabot stopped the deliveries after the DEP ruled that the company had met its obligations under a state order. Affected families were forced to scramble for new sources of water. Filmmaker Josh Fox, actor Marc Ruffalo and others donated bottled water that met some of the families’ needs. The federal EPA recently found dangerous contaminants in well water in Dimock and ordered a resumption of water deliveries for four of the families. Pennsylvania officials have declined to extend public water lines to the affected families, estimating the cost at $12 million.11
New York City water aqueduct threatened
The USGS concluded that under the state plan, hydraulic fracturing fluids could reach and damage New York City’s West Delaware Aqueduct, an underground tunnel that brings drinking water to the city from reservoirs in the Catskill Mountains. Naturally occurring fractures “may potentially provide pathways for the migration of pressurized fluids over significant distances,” the USGS wrote. It suggested that the state’s proposal to require site-specific permits in a 1,000-foot zone around the aqueduct might prove inadequate.12 The USGS focused only on threats to the West Delaware Aqueduct, one of several underground aqueducts that carry water to New York City from the Marcellus Shale region.
An earlier assessment commissioned by New York City’s Department of Environmental Protection (DEP) also concluded that drilling might endanger the West Delaware Aqueduct and other tunnels that carry the city’s water, for reasons similar to those cited by the USGS. The city’s DEP found that naturally occurring underground pathways near the tunnels “can extend up to seven miles laterally and up to 6,000 feet in depth.” It added:
“The vertical and lateral persistence of these features in conjunction with the potential for failed casings or other unforeseen occurrences could result in significant surface and subsurface contamination of fresh water aquifers, as illustrated by incidents in other well fields, most notably documented in Garfield County, Colorado (migration of toxic formation material through subsurface fractures) and Dimock, Pennsylvania (migration of natural gas to the surface via improperly cased wells). Similar mechanisms could permit migration of material into the fresh water aquifers that comprise the NYC West-of-Hudson watersheds and present potential risks to water quality and tunnel lining integrity.”13
Based on this assessment, the city agency recommended several preventive measures, including barring drilling within seven miles of several aqueducts and a drilling ban within two miles of other water tunnels.14
Underground faults, water supplies unmapped
The USGS raised serious questions about the state’s significant undercount of natural faults throughout the gas-rich Marcellus Shale formation. If drilling and hydraulic fracturing were permitted directly underneath faults, the federal agency said, contaminants could flow upward into underground aquifers. It noted that there are generally far more natural faults in bedrock overlying the Marcellus Shale than elsewhere.15
In a study that focused on the Marcellus Shale in New York and Pennsylvania and was published last year by the National Academy of Sciences, researchers from Duke University reported finding levels of natural gas an average of 17 times higher in water wells close to active natural gas wells than in water wells in non-active drilling areas. The most likely cause, they said, was leaky well casings, but they also raised the possibility that some gas migrated through “extensive fracture systems” in rock above the shale formations. Another factor, they said, might be gas migration through many older, un-cased wells abandoned during 150 years of drilling in Pennsylvania and New York.16
USGS urges better reporting
The USGS said that the depths of underground drinking water sources are not well documented and must be established so that drilling companies can design casing and cementing to prevent migration of gas or saltwater into underground drinking water supplies. The agency faulted New York state regulators for failing to require drilling companies to map underground fresh water and salt water sources and, as well, shallow gas formations before they drill extensively. It called these determinations critical to the design and installation of effective casing and cementing.17
Cuomo should emulate Maryland’s O’Malley
The USGS assessment makes clear that New York is not ready for shale gas drilling on any level. Given Cuomo’s commitment to science, it is hard to see how he could come to a different conclusion. Cuomo should halt the state’s drilling plan and let scientists like those at USGS continue their work so that New Yorkers can know whether high volume hydraulic fracturing and horizontal drilling can be conducted safely before drilling begins.
That’s essentially the approach Maryland Gov. Martin O’Malley has taken. His administration has embarked on a detailed study of potential drilling impacts, to be finished by 2014. Until then, O’Malley has committed not to allow gas drilling companies to deploy this controversial technique in Maryland’s portion of the Marcellus Shale.18
Meanwhile, the EPA is conducting a nationwide study on hydraulic fracturing’s impact on water and a separate inquiry in Pavillion, Wyo., where the agency concluded in a draft report that hydraulic fracturing likely contaminated groundwater on which the community relies for its drinking water and agricultural needs.
By proceeding with drilling in the face of warnings by USGS, the EPA and other experts, “Cuomo would be betting nothing of significance will go wrong,” Albany Times-Union columnist Fred LeBrun wrote in a Jan. 15, 2012, column. “Given the enormity of the possibilities, that’s a dumb bet.”19
Will Cuomo make a multi-billion-dollar gamble with the state’s drinking water and the health of New Yorkers? The upside, in the form of jobs and revenues from gas production, is modest. The downside, if anything goes wrong, is incalculable. Why chance it?

The U.S. Environmental Protection Agency (EPA) released a draft analysis of data Dec. 8 from its Pavillion, Wyoming ground water investigation. At the request of Pavillion residents, EPA began investigating water quality concerns in private drinking water wells three years ago. Since that time, in conjunction with the state of Wyoming, the local community, and the owner of the gas field, Encana, EPA has been working to assess ground water quality and identify potential sources of contamination.
EPA constructed two deep monitoring wells to sample water in the aquifer. The draft report indicates that ground water in the aquifer contains compounds likely associated with gas production practices, including hydraulic fracturing. EPA also re-tested private and public drinking water wells in the community. The samples were consistent with chemicals identified in earlier EPA results released in 2010 and are generally below established health and safety standards. To ensure a transparent and rigorous analysis, EPA is releasing these findings for public comment and will submit them to an independent scientific review panel. The draft findings announced Dec. 8 are specific to Pavillion, where the fracturing is taking place in and below the drinking water aquifer and in close proximity to drinking water wells—production conditions different from those in many other areas of the country.
Natural gas plays a key role in our nation’s clean energy future and the Obama administration is committed to ensuring that the development of this vital resource occurs safely and responsibly. At the direction of Congress, and separate from this ground water investigation, EPA has begun a national study on the potential impacts of hydraulic fracturing on drinking water resources.
“EPA’s highest priority remains ensuring that Pavillion residents have access to safe drinking water,” said Jim Martin, EPA’s regional administrator in Denver. “We will continue to work cooperatively with the state, Tribes, Encana and the community to secure long-term drinking water solutions. We look forward to having these findings in the draft report informed by a transparent and public review process. In consultation with the Tribes, EPA will also work with the state on additional investigation of the Pavillion field.”
Findings in the Two Deep Water Monitoring Wells:
EPA’s analysis of samples taken from the agency’s deep monitoring wells in the aquifer indicates detection of synthetic chemicals, like glycols and alcohols consistent with gas production and hydraulic fracturing fluids, benzene concentrations well above Safe Drinking Water Act standards and high methane levels. Given the area’s complex geology and the proximity of drinking water wells to ground water contamination, EPA is concerned about the movement of contaminants within the aquifer and the safety of drinking water wells over time.
Findings in the Private and Public Drinking Water Wells:
EPA also updated its sampling of Pavillion area drinking water wells. Chemicals detected in the most recent samples are consistent with those identified in earlier EPA samples and include methane, other petroleum hydrocarbons and other chemical compounds. The presence of these compounds is consistent with migration from areas of gas production. Detections in drinking water wells are generally below established health and safety standards. In the fall of 2010, the U.S. Department of Health and Human Services’ Agency for Toxic Substances and Disease Registry reviewed EPA’s data and recommended that affected well owners take several precautionary steps, including using alternate sources of water for drinking and cooking, and ventilation when showering. Those recommendations remain in place and Encana has been funding the provision of alternate water supplies.
Before issuing the draft report, EPA shared preliminary data with, and obtained feedback from, Wyoming state officials, Encana, Tribes and Pavillion residents. The draft report is available for a 45 day public comment period and a 30 day peer-review process led by a panel of independent scientists.
