Penn State Extension ups awareness of testing
CHAMBERSBURG — Homeowners often don’t know the quality of the water they are drinking, and an estimated one third of their wells are contaminated with bacteria.
About one quarter of homes in Franklin County get their drinking water from private wells.
Typically only half of homeowners ever have their water tested, and then only once, according to Penn State Extension Educator Thomas Richard McCarty.
“The major risk for most people is contamination from bacteria,” he said. “This is hidden both from sight and taste. Health effects may be hidden too by building resistance to the presence of bacteria, which suffices as long as bacteria counts are low and the householders are in generally good health. Symptoms properly due to poor water may easily be blamed on something else.”
Penn State Extension is offering discounted water testing kits this week.
According to Penn State Extension data for well water in Franklin County:
— About 35 percent of private wells have coliform bacteria in their water. Coliform bacteria come from soil, sewage, or manure and enter groundwater from heavily fertilized areas – home lawns, farm fields or septic systems.
— One in 10 has fecal coliform levels exceeding safe drinking water standards. This branch of the coliform family includes the dreaded E. coli.
— One of every six have nitrates above the limit for drinking water. Nitrate is of concern when infants under six months drink the water or older people with stomach problems.
— One of every 13 homes supplied by a well has lead levels exceeding the maximum allowable concentration. Children absorb more of the lead in their diet than adults do. Lead in water comes primarily from solder joints in copper pipe. Exposure to high levels of lead can result in delays in physical and mental development, along with slight deficits in attention span and learning abilities. Adults exposed to lead over a number of years can develop high blood pressure or kidney problems.
“The lack of testing by well owners is not for a lack of concern over their water quality, but instead, a lack of awareness and understanding of what testing should be done,” according to a 2009 Penn State study Drinking Water Quality in Rural Pennsylvania. “The great majority of well owners that were told of health-related water quality issues in their water supply had voluntarily solved the problem within one year.”
A deeper well does not always have purer water. Limestone bedrock has more to do with bacterial contamination of wells than does the depth of the well, according to a 2001 U.S. Geological Survey study of wells in south-central Pennsylvania. Bacterial concentrations actually increased with depth to the waterbearing zone in limestone. Many of the wells in Franklin County are drilled in limestone geology.
Franklin County lacks current data on the use of private wells.
“The 1980 Census reported that 63 percent of homes were on public water,” said Phil Tarquino, chief of the county planning department. “The remaining 37 percent were on drilled wells, dug wells or cisterns. It would seem that the percent of homes on public water has increased in the last 30 years as most new development has occurred in areas where public water is located. In addition public water has been extended to areas that were previously on wells or cisterns.”
Pennsylvania has more residents using private wells than any other state, except Michigan, and each year another 20,000 are drilled, according to Penn State’s manual for well owners.
McCarty said he is at a loss to explain why interest in Penn State’s water testing program has declined of the years. A steeply discounted program in Adams County attracted few participants.
State investigating methane in water near Dimock Twp.

State environmental regulators are investigating a possible case of methane migrating into water supplies just north of the 9-square-mile box in Dimock Township where the state halted a gas driller’s operations because of methane contamination in 2010.
Regulators with the state Department of Environmental Protection emphasized that they have not determined the source of elevated methane discovered in two Susquehanna County water wells and whether it is caused by Marcellus Shale drilling or a natural occurrence of gas in the aquifer.
One focus of the investigation is Cabot Oil and Gas Corp.’s Greenwood 1 well, where the company recently squeezed additional cement between steel barriers that are meant to seal off gas and fluids from the aquifer.
The work in late March was an effort to stop the problem, DEP spokesman Kevin Sunday said, even though inspectors have not pinpointed the well as the cause.
“The next step is to determine the effectiveness of the remediation work and to continue water well sampling,” he said.
Regulators began investigating the elevated methane levels in August 2010 after a resident complained about water quality.
The gas wells being evaluated are less than 400 feet from the northern boundary of a section of Dimock where Cabot’s drilling and hydraulic fracturing operations have been on hold since April 2010, when state regulators blamed faulty Cabot wells for allowing shallow methane to channel into 18 private water wells. Cabot disputes the state’s findings in that case.
The current investigation is separate from the ongoing review of Cabot’s wells in the off-limits area.
Cabot spokesman George Stark said Friday that the company “always investigates landowners’ concerns as they are brought to our attention. Cabot has been working closely with the Department of Environmental Protection on this matter and will continue to do so with the best interest of our landowners in mind.”
Neither of the two water wells involved in the current investigation has been vented because one well is buried and has not been located and inspections of the other have not found gas trapped in the open space above the water in the well, Sunday said.
Methane in drinking water is not known to cause any health risks, but at high concentrations it can seep out of water into the air and create an explosion hazard in enclosed spaces.
The state has not reached a determination 20 months into the investigation because a number of factors need to be considered, including the construction of nearby gas wells and identifying features of the methane, DEP spokeswoman Colleen Connolly said.
“It’s not different from any case,” she said. “There are just many issues to deal with.”
The Greenwood 1 well was the first Marcellus Shale well drilled by Cabot in Dimock, in September 2007, according to state records.
Three horizontal wells later drilled on the same pad in November 2009 and May 2010 were among the top-producing wells in the state early last year.
Those wells, the Greenwood 6, 7 and 8, have also been evaluated as part of the investigation. Cabot was cited by DEP for a “failure to case and cement” the three wells “to prevent migrations into fresh groundwater” in January 2011 but Cabot has argued in a letter to the state that the wells were properly constructed and the violations should be rescinded.
Connolly said that DEP is addressing the violations with Cabot. The defects cited by the department “could have been a means of allowing methane to migrate into the fresh groundwater, but that doesn’t necessarily mean the water supply has been impacted,” she said.

Lack of snow and rain prompt Pa. officials to discuss drought potential
www.therepublic.com/view/story/33c64dbf097042838eb0ad5d3aa8f9a5/PA–Drought-Fears/
HARRISBURG, Pa. — Just after Pennsylvanians dried off from one of the wettest years on record, professional weather-watchers are becoming concerned about a potential drought in the central and eastern parts of the state.
The state’s Drought Task Force, which includes representatives of the Department of Environmental Protection, the Pennsylvania Emergency Management Agency, the National Weather Service and other government agencies, will meet April 25 to discuss the effects of a winter with little snowfall and a drier-than-usual spring, officials said Tuesday.
It remains to be seen whether that leads to the DEP declaring a drought watch encouraging residents in certain areas to conserve water, as Maryland officials did last week for most of the Eastern Shore.
“At this point we’re not taking any action,” said Ruth Miller of PEMA, which helped direct relief efforts during last year’s historic flooding from Hurricane Irene and Tropical Storm Lee, which killed 18 people and damaged or destroyed tens of thousands of homes and businesses.
Now, in contrast to those back-to-back disasters in August and September, the Susquehanna and Delaware rivers are flowing at record low rates for this time of year.
Susan Weaver, a DEP official who serves as the state drought coordinator, said officials assess data on precipitation, surface water, ground water and soil moisture in 90-day increments before deciding whether to issue a drought watch or a more emphatic drought warning.
“The tough part is what’s going to happen tomorrow,” Weaver said.
In August, “we issued a drought watch and I swear to God the next day it started to rain and it didn’t stop,” she said.
On Tuesday, the Susquehanna was flowing at around 14,000 cubic feet per second — less than 20 percent of its normal rate and the slowest flow since 1910, said hydrologist Charles Ross at the weather service office in State College. The average depth was barely half the normal seven feet, he said.
Still, “all it’s going to take is some average rain and we’ll probably be in pretty good shape,” Ross said.
The situation was similar on the Delaware, where the flow in Trenton, N.J., was measured at less than 4,000 cubic feet per second — the lowest for that date in the 98 years it has been measured.
“We’ve actually been setting records for a week or so,” said Clarke Rupert, spokesman for the Delaware River Basin Commission.
Susan Obleski, spokeswoman for the Susquehanna River Basin Commission, said dry conditions along streams that feed the river have led the commission to temporarily suspend permits that allow some natural gas drilling companies to use that water. So far, 14 permits held by eight companies have been suspended.
“They have multiple sources (of water), so it doesn’t mean that (a) particular company would shut down,” she said.
Ex-DEP Official Says All Pa. Oil, Gas Waste Needs Treatment
www.manufacturing.net/news/2012/04/ex-dep-official-says-all-pa-oil-gas-waste-needs-treatment
Mon, 04/16/2012
PITTSBURGH (AP) — A former top environmental official says Pennsylvania’s successful efforts to keep Marcellus Shale wastewater away from drinking water supplies should be extended to all other oil and gas drillers.
“It’s the same industry. It is the same contaminants. And the goal should be the same,” said George Jugovic Jr., who was formerly the Department of Environmental Protection’s southwest regional director. He’s now president of PennFuture, an environmental group.
An AP analysis of state data found that in the second half of 2011 about 1.86 million barrels — or about 78 million gallons — of drilling wastewater from conventional oil and gas wells were still being sent to treatmentplants that discharge into rivers.
The core issue is whether a problem in waterways has been solved, or if more needs to be done.
In 2010 health experts raised alarms when they found soaring levels of ultra-salty bromides in rivers and streams that are major sources of drinking water. The general view was that wastewater from Marcellus Shalegas drilling — polluted with heavy bromides from deep underground — was contributing to the problem.
High levels of bromides can contaminate drinking water with levels that exceed national safety standards and are potentially harmful. Though not considered a pollutant by themselves, the bromides combine with the chlorine used in water treatment to produce trihalomethanes, which may cause cancer if ingested over a long period of time.
Bromide levels were so high in rivers during 2010 that they caused corrosion at some plants that were using the water.
But since the spring of 2011 most Marcellus drillers have been recycling the fluids, or sending then to deep underground wells mostly in Ohio.
The gas-rich Marcellus, which lies thousands of feet underground, has attracted a gold rush of drillers who have drilled almost 5,000 new wells in the last five years. But the state also has about 70,000 older oil and gaswells, according to DEP statistics, that target different, shallower reserves.
Researchers say the bromide levels did drop last summer, but they had also expected even more of a decline after virtually all of the Marcellus Shale drillers stopped disposing wastewater into plants that discharge into rivers.
But conventional oil and gas wells weren’t included in last year’s recycling push — a loophole that state environmental officials downplayed at the time.
Jugovic said DEP secretary Mike Krancer should now take “the next step” and get voluntary compliance from the rest of the gas industry.
“It’s hard scientifically to justify a distinction between treating conventional wastewater differently. The wastewater is being disposed in plants that are not capable of treating those contaminants,” he said.
Dave Mashek, a spokesman for the Pa. Independent Oil & Gas Association, declined to comment.
Kevin Sunday, a DEP spokesman, claimed that the volume of conventional oil and gas waste is “substantially smaller” than the Marcellus amounts.
But the AP found that 78 million gallons of oil and gas wastewater were still being taken to treatment plants in the last half of 2011 — about 33 percent less than the Marcellus quantity that was raising concerns in 2010, but still a substantial amount. If that rate continues, the conventional wells will send about 150 million gallons of the wastewater to treatment plants that discharge into rivers this year.
Sunday said the agency encourages wastewater recycling, “regardless of the industry involved,” and added that the conventional oil and gas drillers don’t produce as much wastewater as the Marcellus drillers.
Sunday also said that the agency has created a new, revised permit to encourage recycling of waste. Ten facilities have applied for the new permit, and if all are approved, that would double the number of such facilities in the state.
David Sternberg, a spokesman for the U.S. Environmental Protection Agency, didn’t directly answer a question about whether there was any scientific justification for treating the non-Marcellus waste differently. Sternberg said EPA, which urged Pennsylvania regulators last year to halt the dumping, is working closely with state regulators “to ensure that, where wastewater treatment facilities are accepting oil and gas wastewaters, discharges from these treatment facilities are in compliance with the Clean Water Act.”
Jugovic said that some previous assumptions about the non-Marcellus waste turned out to be false. For example, there were suggestions that it generally contained much lower levels of bromides and other contaminants.
He said some of the shallow wells had very high levels of total dissolved solids and other contaminants that can be a problem for drinking water supplies.
Jugovic also said that the fact that 97 percent of Marcellus drillers appear to be complying with the wastewater restrictions raises a fairness issue. Why, he asked, should the conventional oil and gas drillers and the remaining 3 percent of drillers get a pass?
Now, researchers are waiting for expected lower river levels in the summer, to see if the bromide problem has really gone away. The higher flows in early spring dilute any contaminants and make it harder to draw conclusions about the bromides.
Drilling law hurts health, docs say
thetimes-tribune.com/news/gas-drilling/drilling-law-hurts-health-docs-say-1.1298897#axzz1rpg4bvIU
Published: April 12, 2012
PITTSBURGH – Public health advocates and doctors on the front lines of Pennsylvania’s natural-gas-drilling boom are attacking the state’s new Marcellus Shale law, likening one of its provisions to a gag order and complaining that vital research money into health effects was stripped at the last minute.
Doctors say they don’t know what to tell patients who suspect their ailments are related to nearby gas industry activity because of a lack of research on whether the drilling of thousands of new wells – many near houses and drinking-water supplies – has made some people sick.
Yet when legislative leaders and the governor’s office negotiated the most sweeping update of the state’s oil and gas law in a quarter century, they stripped $2 million annually that included a statewide health registry to track respiratory problems, skin conditions, stomach ailments and other illnesses potentially related to gas drilling.
Just last week, the Department of Health refused to give The Associated Press copies of its responses to people who complain that drilling had affected their health. That lack of transparency – justified in the name of protecting private medical information – means the public has no way of knowing even how many complaints there are or how many are valid.
Studies are urgently needed to determine if any of the drilling has affected human health, said Dr. Poune Saberi, a University of Pennsylvania physician and public health expert.
“We don’t really have a lot of time,” said Saberi, who said she’s talked to about 30 people around Pennsylvania over the past 18 months who blame their ailments on gas drilling.
Working out of public view, legislative negotiators also inserted a requirement that doctors sign a confidentiality agreement in return for access to proprietary information on chemicals used in the hydraulic fracturing, or fracking, process.

First 11 Dimock homes sampled by EPA show no health concerns

The first 11 Dimock Township water supplies tested by the U.S. Environmental Protection Agency did not reveal levels of contamination that could present a health concern, but the samples indicated the presence of arsenic and other compounds that will require further tests at some homes, the agency said Thursday.
Agency officials hand delivered test results to residents whose wells were sampled during the week of Jan. 23 and will meet again with the families individually to review the results and answer questions.
The first test results reported Thursday represent about a sixth of the data collected by the EPA over weeks of sampling in a nine-square-mile area of Dimock where the agency is investigating the potential impact of nearby natural gas drilling on water supplies.
In a statement Thursday, the EPA said samples from six of the 11 homes showed concentrations of sodium, methane, chromium or bacteria, but all were within the safe range for drinking water. The sampling results also identified arsenic in two homes’ water supplies, both of which are being sampled again by the agency.
“Although the (arsenic) levels meet drinking water standards, we will resample to better characterize the water quality of these wells,” EPA spokesman Roy Seneca said in the statement.
Three of the 11 homes tested during the first week of sampling are receiving replacement water deliveries from the EPA. Those deliveries will continue “while we perform additional sampling to ensure that the drinking water quality at these homes remains consistent and acceptable for use over time,” Seneca said.
The agency began testing about 60 water wells in January after the EPA’s review of past tests by the state and other groups raised concerns about contamination from Marcellus Shale drilling.
Seneca said that the agency will share more test results with Dimock homeowners “as further quality assured data becomes available for the remaining homes.”
The statement released by the EPA did not include a complete list of the compounds detected in the first 11 water supplies.
In the test results given to the families, the EPA highlighted compounds found at concentrations that exceeded what the agency described as “trigger levels” based on risk-based screening levels or the standards for public drinking water supplies.
Although all of the results were reviewed by a toxicologist before they were presented to residents, compounds above a trigger level were reviewed sooner by toxicologists and processed quicker by the agency “should we need to take an immediate action to provide water,” Seneca said.
“EPA conducted those reviews and found no health concerns,” he said.
Dimock resident Scott Ely said his test results showed five compounds above their trigger levels, including arsenic, chromium, lithium, sodium and fluoride. The arsenic level in his well water, 7.6 micrograms per liter, was below the federal drinking water standard of 10 micrograms per liter but above the 3 micrograms per liter chronic drinking water screening level for children established by the Agency for Toxic Substances and Disease Registry.
Ely, who has three small children in his home, said the results reveal “nothing surprising: my water is contaminated.”
The number of compounds in his water well that triggered an expedited toxicological review “just confirms that we have issues,” he said.
The natural gas industry said that the results confirm that their operations have not affected drinking water.
George Stark, a spokesman for Cabot Oil and Gas Corp., the firm drilling extensively in the township, said the company is “pleased that data released by EPA today on sampling of water in Dimock confirmed earlier findings that Dimock drinking water meets all regulatory standards.”
He said that the company will continue to work with the EPA as well as state and local regulators to address concerns in Dimock, but he chided federal regulators for intervening in the case.
“We hope that lessons learned from EPA’s experience in Dimock will result in the agency improving cooperation with all stakeholders and to establish a firmer basis for agency decision making in the future,” he said.

Federal environmental and health agencies collect data from Dimock families

Officials from federal environmental and public health agencies met with residents of Dimock Township late last week to discuss the impacts of Marcellus Shale natural gas drilling and to gather water-test results from families affected by methane migration.
Three representatives from the Environmental Protection Agency and the Agency for Toxic Substances and Disease Registry visited Thursday with families around Carter Road, an area of Susquehanna County where state regulators have linked increased methane in water supplies to faulty natural gas wells.
“They wanted information; they wanted documentation,” Dimock resident Scott Ely said. “They are looking to see if there is any environmental impact that would threaten life or health.”
Efforts to reach an EPA spokeswoman were unsuccessful Friday, when government offices were closed for Veterans Day.
Natural gas drilling is largely regulated in Pennsylvania by the state Department of Environmental Protection, but the EPA is conducting a multiyear study to determine if there is a link between hydraulic fracturing, or fracking, and contaminated water supplies.
The Agency for Toxic Substances and Disease Registry is an arm of the U.S. Department of Health and Human Services that works to prevent harmful exposures to toxic substances.
Dimock resident Victoria Switzer said the agencies were interested in copies of water sample results from her well, including data gathered by scientists not affiliated with the state or natural gas drilling contractors.
She also outlined her concerns that the state Department of Environmental Protection weakened enforcement actions against Cabot Oil and Gas Corp., the operator that DEP deemed responsible for increased methane in water supplies. Cabot denies it impacted the water and says the elevated methane pre-existed its operations.
“The watchdog is licking the hand of the thief that is giving it a steak,” she said. “We want to get this issue to a high place.”
Efforts to reach a DEP spokeswoman were unsuccessful Friday.

Lawyer: Dimock water unsafe; deliveries should go on

Attorneys for Dimock Twp. families suing a natural gas driller over contamination claims are asking the state’s chief oil and gas regulator to reverse his decision allowing fresh water deliveries to the families to end.
Tate Kunkle, a lawyer representing the 11 families in a suit against Cabot Oil and Gas Corp., wrote to the head of the Department of Environmental Protection’s Office of Oil and Gas Management on Thursday to rebut Cabot’s claim that the families’ well water is safe and that proposed treatment systems work.
He cited tests over the past 22 months showing elevated levels of lead, aluminum, iron, toluene, methane and manganese in some of the water supplies, as well as detection of chemicals found in synthetic sands, hydraulic fluid and antifreeze that “are not naturally occurring and that are associated with natural gas drilling.”
“The fact is that the water in the Dimock/Carter Road Area remains unsafe for drinking, even with Cabot’s proposed ‘whole house treatment system,’ ” Mr. Kunkle wrote.
The DEP determined that faulty Cabot Marcellus Shale wells allowed methane to seep into aquifers in the Susquehanna County township, a finding the company disputes. Families have been relying on deliveries of fresh bottled and bulk water for drinking, bathing and cooking for nearly three years.
On Oct. 19, the agency found that Cabot had met the obligations necessary to end delivery of the water supplies outlined in a December settlement between Cabot and DEP. The settlement was reached after the Rendell Administration abandoned plans to build a public waterline to the homes and sue Cabot for the costs.
Those obligations included funding escrow accounts for 19 affected families with twice the tax-assessed value of their properties and offering to install methane-removal systems in the homes. The obligations did not include restoring the residents’ well water to its original quality or reducing levels of dissolved methane in the aquifer.
A DEP spokeswoman referred to a recent letter to the editor published by DEP Secretary Michael Krancer in the (Chambersburg) Public Opinion for his comments on the issue.
Mr. Krancer wrote that Cabot met the requirements outlined in the December agreement “and the law, in turn, requires DEP to follow its obligations – which we have done.
“The real issue here is not safety,” he continued. “It’s about a very vocal minority of Dimock residents who continue to demand that taxpayers should foot the bill for a nearly $12 million public waterline along Route 29 to serve about a dozen homes.”
Cabot argues that the methane in Dimock water supplies occurs naturally and is not a result of its gas-drilling activities. It has produced data showing naturally occurring methane is detectable in 80 percent of Susquehanna County water supplies.
The company plans to stop the fresh water deliveries on or before Nov. 30.
Cabot spokesman George Stark said Friday that the company is reviewing Mr. Kunkle’s letter. “Cabot continues to fully cooperate with the DEP regarding our operations,” he said.
In his letter, Mr. Kunkle quoted email messages from a Dimock resident who accepted a Cabot treatment system and found it failed to treat turbidity and metals in her water.
Mr. Kunkle accused Cabot of misrepresenting or selectively reporting water-quality test results and charged DEP with colluding with and “coddling” Cabot while abandoning the regulatory requirement for drillers to restore or replace tainted water supplies.
“To be sure, PADEP has taken a stance: profits of a private corporation from Texas are more important than the constitutional right to pure water of the Commonwealth’s residents,” he wrote.

Critic disputes Penn State findings and thinks potential well water contamination overlooked

Study: Gas drilling not polluting water
The natural gas industry is pointing to a Penn State University study to boost its mantra that gas drilling is not linked to pollution of water wells.
But a drilling critic says the study found increased levels of a harmful chemical in water wells after gas drilling occurred nearby. He thinks other aspects of the study overlooked potential well water contamination.
“The Impact of Marcellus Gas Drilling on Rural Drinking Water Supplies” was authored by Penn State water quality experts led by Elizabeth Boyer, associate professor of water resources, director of the Pennsylvania Water Resources Research Center and assistant director of the Penn State Institutes of Energy & Environment.
The research was sponsored by a grant from the Center for Rural Pennsylvania, a bipartisan legislative agency within the state General Assembly. The goal was a large-scale study of water quality in private water wells in rural Pennsylvania before and after nearby Marcellus Shale drilling.
For the study, the researchers evaluated water sampled from 233 water wells near gas wells in 2010 and 2011. The first phase focused on 48 private water wells located within 2,500 feet of a nearby shale well pad. The second phase focused on 185 private water wells located within 5,000 feet of a shale well pad.
During the first phase, researchers collected pre- and post-drilling water well samples and analyzed them for water quality. In the second phase, researchers or homeowners collected only post-drilling water well samples and analyzed them for water quality. The post-drilling analyses were compared with existing pre-drilling test records.
John Krohn, spokesman for Energy In Depth Northeast Marcellus Initiative, noted excerpts from the report that said analysis of the water tests “did not suggest major influences from gas well drilling (or hydraulic fracturing) on nearby water wells.”
Hydraulic fracturing, or fracking, is the high-pressure injection of millions of gallons of water, sand and chemical additives deep underground to extract natural gas trapped in shale rock.
The study also found no clear link between methane migration and natural gas production, Krohn said.
Methane is a gas that some residents living near gas wells have lit on fire as it escaped from their kitchen faucets along with their well water.
Krohn also noted 40 percent of the water wells tested failed at least one safe drinking water standard, mostly for coliform bacteria, turbidity and manganese, before drilling occurred. This shows a need for uniform water well construction standards that don’t exist in Pennsylvania, as well as a need for education of water well owners.
Dr. Tom Jiunta, founder of the local Gas Drilling Awareness Coalition, said study findings of increased levels of bromide and sediment/metal levels in wells after drilling/fracking were of particular concern to him.
“This finding alone shows that many wells near drilling sites are impacted by migration of underwater brines and possible drilling muds, both hazardous to drinking water supplies,” he said.
Bromide itself is not a health threat, but elevated levels “can create an indirect health issue as it may combine with other elements in water to cause carcinogenic compounds,” the report states.
Jiunta said nearly 80 percent of the water wells were not pre-tested for methane, bromide or oil/grease because well owners couldn’t afford the expensive tests. “This skews the data,” he said.
Jiunta also said the study considers only short-term changes in well water after nearby gas wells were drilled – less than three-month time periods. He said that time period is “inadequate for determining contamination,” citing a Temple University engineering professor who said most problems with underground water contamination would most likely take several years to be detected.
The Penn State study was released as the U.S. Environmental Protection Agency begins a federal probe into whether hydraulic fracturing is spoiling and diminishing drinking water supplies.
The agency’s final study plan was released Thursday. The first results will be available in 2012.
