Lead Poisoning Prevention Week (Oct. 23-30)

PHILADELPHIA (October 25, 2011) — The U.S. Environmental Protection Agency has declared October 23-30, 2011 Lead Poisoning Prevention Week as part of the agency’s on-going efforts to make families aware of the hazards presented by lead and lead-based paint in the home and places where children under six years of age are regularly present.

Lead is a toxic metal that was used for many years in paint and other products found in and around our homes. Beginning in 1978, lead-based paint was banned from residential use, leaded gasoline has been eliminated, and household plumbing is no longer made with lead materials.

Lead is a major environmental health hazard for young children. Research shows that blood lead levels of 10 micrograms per deciliter of blood (µg/dL) in young children can result in lowered intelligence, reading and learning disabilities, impaired hearing, reduced attention span, hyperactivity, and antisocial behavior. However, there currently is no demonstrated safe concentration of lead in blood, and adverse health effects can occur at lower concentrations.

If caught early, these effects can be limited by reducing exposure to lead or through medical treatment. Children under six years of age are particularly at risk and pregnant women should avoid exposure to lead as the effects can be passed on to the child.

If your home was built before 1978, lead still may be present. The most common source of household lead exposure is through deteriorating lead-based paint.

EPA’s Lead-Based Paint Renovation, Repair and Paint Rule (RRP) became effective on April 22, 2010. Under the RRP, anyone paid to work on residences built before 1978 and/or facilities where children under the age of six are regularly present (such as daycare centers, schools, clinics, etc.) are required to be Certified Lead Safe by EPA and must be trained to follow specific work practices to reduce lead contamination, and provide the EPA publication “Renovate Right” to owners and/or residents prior to the commencement of the work.

The rule applies when the renovation or repair disturbs six sq. ft. of interior (about the size of a standard poster) or 20 sq. ft (about the size of a standard door) of exterior painted surfaces.

The rule does not apply to individuals doing work on their personal residences. However, EPA recommends that lead-safe work practices be used by individual homeowners whenever possible.

Recognizing that families have a right to know about lead-based paint and potential lead hazards in their homes, EPA and the U.S. Department of Housing and Urban Development developed the Lead-Based Paint Disclosure Rule which has been in effect since 1996.

The Lead-Based Paint Disclosure Rule requires that both the owners of residential rental properties and the sellers of residential property built before 1978, disclose known information on lead-based paint and lead-based paint hazards before a lease or sale takes effect. Sales contracts and leases must include a disclosure form about lead-based paint. Buyers have up to 10 days to check for lead hazards. Further, landlords and sellers must also provide the EPA publication “Protect Your Family from Lead in Your Home.”

Citizens group seeks tougher gas rules

HARRISBURG – Pennsylvania should enact stricter rules to protect air quality and surface water and groundwater from the impact of natural gas drilling, a report issued by the Citizens Marcellus Shale Commission said on Monday.

The commission was formed as a counterpart to Gov. Tom Corbett’s Marcellus Shale Commission and held hearings this fall around the state, including Wysox and Williamsport.

The governor’s commission made no recommendations to control or monitor air pollution from well flaring, equipment leaks and compressor engines, said Thomas Au, a Pennsylvania Sierra Club official.

The citizens’ commission recommends several steps, including more state monitoring of air pollutants in the vicinity of wells and compressor engines and stronger enforcement at drilling sites of state laws that limit truck idling. Other recommendations call for a state drilling tax, restoring the authority of county conservation districts to review stormwater permits and establishing an office of state consumer environmental advocate.

Pennsylvania should ban drilling in flood plains, said John Trallo, a commission member from Sonestown, Sullivan County. Mr. Trallo is chairman of Residents United for Pennsylvania/Sullivan County chapter.

Forest clear-cutting to open space for drilling pads will make future floods even worse than those that hit the region in September, he said.

“We repeatedly heard that natural gas development has moved too quickly,” said Roberta Winters, an official with the League of Women Voters of Pennsylvania about testimony at the hearings. “Pennsylvania was and is still not prepared to limit the risks and address its impact.”

The group’s report appears with time running out for a Senate Republican leader’s call for action on an impact fee bill on natural gas drilling during October. President Pro Tempore Joseph Scarnati, R-25, Jefferson County, is sponsor of an impact fee bill that won tentative approval from a Senate committee last spring but has yet to reach the Senate floor.

Tackling Marcellus Shale factor

Tackling Marcellus Shale factor

BY BRIAN ORAM (GUEST COLUMNIST)
Published: October 23, 2011

In 1795 settlers in Montrose discussed water that would “bubble and catch fire like black powder.” Later it was determined that Salt Spring contained methane gas. What is now Salt Spring State Park in Susquehanna County was once the site of an attempted oil and salt operation.

Today it appears the development of the Marcellus Shale is commercially viable.  Methane is not uniformly distributed in the Marcellus Shale, but it is virtually everywhere in our environment. Methane  can be found in saturated soils, lake sediments, wetlands, landfills, and the Catskill Formation (our source of drinking water) to name a few. There is no drinking water standard for methane gas, but there are guidance levels due to concerns for the potential of accumulation which can create an explosive environment. The guidance level in Pennsylvania is 7 milligrams per liter of methane in water. There also are action levels when airborne concentrations reach 10 percent of the lower explosive limit. The level of methane in water and the level in a confined headspace do not correlate. If gas is collecting in the headspace of a well the problem is that the well is not properly vented and this needs to be corrected. It does not indicate methane is present in the water below.

Prior to Marcellus development it had been my experience that levels of methane can range from not detectable to greater than 28 miligrams per liter. I lit my first tap in 1989.

The concentration of methane gas in water is highly variable. Methane levels can change greatly in the same well in a matter of days and concentrations may vary widely. This was one reason, in 2009, I proposed lowering the recommended action level in Pennsylvania to its current state. The level of methane fluctuation is determined by many factors including barometric pressure, rainfall amounts, ice cover on soil, groundwater levels, water well operation, depth of pump setting, depth of well, and geological setting. All of these factors can cause the headspace and dissolved methane to fluctuate. Given this all residents should vent their wells.

Currently baseline water testing is being done throughout our area. These tests demonstrate that our groundwater is not pure. Local groundwater contains measurable to explosive levels of methane gas and other trace elements. Of specific concern is that up to 50 percent of private wells may not meet a primary drinking water standard because of bacterial contamination, arsenic, barium or lead. I call this the “Marcellus Shale factor.” The development of this natural resource has piqued our attention and is another reason we need to work together to test our water and understand the challenges we face. The only way we can address our groundwater challenges is to understand these issues and take corrective action.

Throughout my career, I have conducted extensive groundwater and private well testing. We created the Water-Research.net Web portal as a free information resource and we are continuing our work on the Citizens Groundwater and Surfacewater Database for our area. In addition, we are conducting a private well owner watershed survey and are planning to offer free radon in water screening. This data warehouse will enable us to better understand our resources, current issues, and track future change. It can also be used to make decisions that ensure the health, safety and welfare of our community and environment.

Recently, the Department of Environmental Protection determined methane levels in Dimock meet the requirements of the consent document agreed to by all parties. It is my hope that continued monitoring will confirm this conclusion and that we all work together to move forward with greater understanding.  We are a community and may not all agree but we must work together – this is our home.

It is critical that local stakeholders form task forces and create community resources to educate, assist and inform ourselves to make educated decisions based on science, not fear. Our first order of business should be the development of private well standards and a program to upgrade existing private wells. This should be in addition to the development of best-management practices for development of the Marcellus Shale in our region. These actions are critical to ensure the health, safety and economic welfare of our citizens and environment.

N.Y. gas drillers’ victory soured by tough new rules

NEW YORK | Fri Oct 21, 2011

People gather on the steps of New York City Hall protesting the states plan for shale oil drilling in the city's watershed in New York January 4, 2010. (Credit: Reuters/Shannon Stapleton)

The end of a drilling ban in New York was meant to be a new dawn for energy companies. After years of waiting, they would finally be able to exploit the richest deposit of natural gas in the country.

But as companies delve into new regulations for drilling in New York, they’re discovering a bitter reality: half the land they had leased for drilling may now be out of bounds.

In proposed new rules for drilling, which are expected to be finalized early next year, the state has imposed an off-limits buffer around its waterways due to environmental concerns about the effects that drilling will have on water supplies.

The buffers are as much as 20 times larger than neighboring, industry-friendly Pennsylvania.

After looking at maps of thousands of potentially forbidden acres, some companies are considering leaving the state altogether, Reuters has discovered.

Royal Dutch Shell, which has leased about 90,000 acres for drilling in New York, reckons that 40 percent of that land could be off limits under the proposed laws, a company source told Reuters after Shell completed modeling of  its acreage in the state.

“We are looking at a potentially significant impact,” the source said.

Inflection Energy, a small independent company with 15,000 acres in New York, is reconsidering drilling there after studies showed that about 60 percent of its acreage might not be drillable.

“It is forcing us to change our business model,” said Inflection chief executive Mark Sexton. “If the regulations go ahead we will allocate more resources to Pennsylvania than New York. Originally we had planned to focus more on New York.”

Inflection had aimed to increase leased land to 50,000 acres.

The revelation of the stiff restrictions on drilling near aquifers and waterways, a previously unreported aspect of environmental regulations proposed this summer, is the latest set-back for shale drillers in New York, where unusually fierce local opposition has stunted development.

It also highlights how tougher state regulations could rein in the rampant expansion of natural gas produced using hydraulic fracturing, or fracking, a controversial technique to extract gas from shale rock deep below the surface by blasting it with chemical-laced water.

Dimock, Pennsylvania Residents Will Stop Receiving Water From Fracking Company

www.huffingtonpost.com/2011/10/19/dimock-pennsylvania-replacement-water_n_1019743.html
MICHAEL RUBINKAM   10/19/11

ALLENTOWN, Pa. — Pennsylvania environmental regulators said Wednesday they have given permission to a natural-gas driller to stop delivering replacement water to residents whose drinking water wells were tainted with methane.

Residents expressed outrage and threatened to take the matter to court.

Cabot Oil & Gas Corp. has been delivering water to homes in the northeast village of Dimock since January of 2009. The Houston-based energy company asked the Department of Environmental Protection for approval to stop the water deliveries by the end of November, saying Dimock’s water is safe to drink.

DEP granted Cabot’s request late Tuesday, notifying the company in a letter released Wednesday morning. Scott Perry, the agency’s acting deputy secretary for oil and gas management, wrote that since Cabot has satisfied the terms of a December settlement agreement requiring the company to remove methane from the residents’ water, DEP “therefore grants Cabot’s request to discontinue providing temporary potable water.”

Residents who are suing Cabot in federal court say their water is still tainted with unsafe levels of methane and possibly other contaminants from the drilling process. They say DEP had no right to allow Cabot to stop paying for replacement water.

Bill Ely, 60, said the water coming out of his well looks like milk.

“You put your hand down a couple of inches and you can’t see your hand, that’s how much gas there is in it. And they’re telling me it was that way all my life,” said Ely, who has lived in the family homestead for nearly 50 years and said his well water was crystal clear until Cabot’s arrival three years ago.

If Cabot stops refilling his 550-gallon plastic “water buffalo” that supplies water for bathing and washing clothes, Ely said it will cost him $250 per week to maintain it and another $20,000 to $30,000 to install a permanent system to pipe water from an untainted spring on his land.

Ely and another resident, Victoria Switzer, said their attorneys had promised to seek an injunction in the event that DEP gave Cabot permission to halt deliveries. The attorneys did not immediately return an email and phone call seeking comment.

Regulators previously found that Cabot drilled faulty gas wells that allowed methane to escape into Dimock’s aquifer. The company denied responsibility, but has been banned from drilling in a 9-square-mile area of Dimock since April of 2010.

Along with its request to stop paying for deliveries of water, Cabot has asked the department for permission to resume drilling in Dimock, a rural community about 20 miles south of the New York state line where 18 residential water wells were found to be polluted with methane. DEP has yet to rule on that request.

Philip Stalnaker, a Cabot vice president, asserted in a Monday letter to DEP that tests show the residents’ water to be safe to drink and use for cooking, bathing, washing dishes and doing laundry. He said any methane that remains in the water is naturally occurring but that Cabot is willing to install mitigation systems at residents’ request.

Months’ worth of sampling data provided by DEP to The Times-Tribune of Scranton show that methane has spiked repeatedly this year in the water wells of several homes, reaching potentially explosive levels in five, the newspaper reported Wednesday.

Cabot cited data from 2,000 water samples taken before the commencement of drilling in Susquehanna County that show that 80 percent of them already had methane.

“The amount of methane in a water supply is neither fixed nor predictable,” and depends on a variety of factors unrelated to drilling, Cabot spokesman George Stark said in an email Wednesday.

Methane is an odorless, colorless, tasteless gas commonly found in Pennsylvania groundwater. Sources include swamps, landfills, coal mines and gas wells. Methane is not known to be harmful to ingest, but at high concentrations it’s flammable and can lead to asphyxiation.

The December 2010 agreement between DEP and Cabot required the company to offer residential treatment systems that remove methane from the residents’ water, and to pay them twice the assessed tax value of their homes. A half-dozen treatment systems have been installed, and Cabot said they are effective at removing the gas.

But residents who filed a federal lawsuit against Cabot are appealing the December settlement. They favor an earlier, scuttled DEP plan that would have forced Cabot to pay nearly $12 million to connect their homes to a municipal water line.

Switzer said it’s inappropriate for the state to allow Cabot to stop the water deliveries while the appeal is pending – and while there still are problems with residents’ water.

“They keep changing the rules to accommodate this gas company. It’s so blatantly corrupt,” she said.

DEP spokeswoman Katherine Gresh said the December settlement gave Cabot the right to halt the deliveries once the company funded escrow accounts for the homeowners and is “independent of the water quality results.”

Cabot plans to inform each homeowner by Nov. 1 that it will discontinue deliveries of bulk and bottled water by Nov. 30. The company also offered to pay for a plumber to reconnect residents’ water wells. Cabot said it will stop delivering replacement water “at its earliest opportunity” to homeowners who refuse to allow testing of their well water.

Drilling’s effects to be analyzed

Penn State database will look at impact of natural gas on groundwater resources.

Researchers at Penn State University will build a database to analyze the impact of natural gas drilling on Pennsylvania’s groundwater resources.

Funded by a $750,000 grant from the National Science Foundation, the research initiative aims to consolidate water data collected by government agencies, universities, industry stakeholders and citizens groups into a searchable database accessible to the public online.

“It’s very clear that the rate of drilling in the state is going faster and faster, and there have been some impacts on water, so we want to help the people of Pennsylvania pull together some of that data and analyze that impact,” said Susan Brantley, project leader and director of the university’s Earth and Environmental Systems Institute.

Brantley said drilling’s effects on the state’s water resources have thus far been localized, and she expects the statewide data will reflect those localized impacts rather than an overall statewide pattern, but the consolidation of data will also give scientists and lawmakers a sense of the industry’s overall impact on the state’s natural resources.

The data will be posted by the university to a website where users will be able to search and plot data using various search criteria, and researchers at Penn State and other colleges will conduct their own analysis of the data as it is posted.

The challenge, Brantley said, will be to encourage well owners to submit their data, as water well testing is frequently done by homeowners and companies who may not wish to make their data public. The database will maintain anonymity, and will have quality control measures in place to ensure data submitted is genuine and valid, Brantley said.

Eventually, the university plans to train community groups to collect and interpret water data, and is planning a workshop in the spring.

Wilkes University professors Ken Klemow and Dale Bruns, who are conducting their own Department of Energy-funded surface water tests and are working towards building a similar database to Penn State’s for Northeastern Pennsylvania, said the Penn State database will complement their own research and that they hope to find ways to work with the Penn State researchers.

“People are very concerned about water quality as it relates to the Marcellus,” Klemow said. “There have been some statements made, especially in the press, saying that water supplies have been completely decimated, and then you have the industry saying there’s been no impact at all. To settle this question you really need to do the good science.

Battle in Dimock: Gas vs. water

www.timesleader.com/news/Battle_in_Dimock__Gas_vs__water_10-16-2011.html

October 17, 2010

Some wells have been fouled in an area where drilling for natural gas is intensive.

DIMOCK — Three years after residents first noticed something wrong with their drinking-water wells, tanker trucks still rumble daily through this rural Northeastern Pennsylvania village where methane gas courses through the aquifer and homeowners can light their water on fire.

One of the trucks stops at Ron and Jean Carter’s home and refills a 550-gallon plastic “water buffalo” container that supplies the couple with water for bathing, cleaning clothes and washing dishes. A loud hissing noise emanates from the vent stack that was connected to the Carters’ water well to prevent an explosion — an indication, they say, the well is still laced with dangerous levels of methane.

Recent testing confirms that gas continues to lurk in Dimock’s aquifer.

“We’re very tired of it,” says Jean Carter, 72. Tired of the buffalo in their yard, tired of worrying about the groundwater under their house, and tired of the fight that has consumed Dimock every day since the fall of 2008.

Like everyone else here, the Carters are eager to turn the page on the most highly publicized case of methane contamination to emerge from the early days of Pennsylvania’s natural-gas drilling boom. Cabot Oil & Gas Corp., the Houston-based energy firm held responsible and fined hundreds of thousands of dollars for polluting the groundwater, is just as anxious to resume drilling in a 9-square-mile area of Dimock that has been placed off-limits to the company until it repairs the damage.

State regulators blame faulty gas wells drilled by Cabot for leaking methane into Dimock’s groundwater. It was the first serious case of methane migration connected to Pennsylvania’s 3-year-old drilling boom, raising fears of potential environmental harm throughout the giant Marcellus Shale gas field. Drilling critics point to Dimock as a prime example of what can and does go wrong.

Methane from gas-drilling operations has since been reported in the water supplies of several other Pennsylvania communities, forcing residents to stop using their wells and live off water buffaloes and bottled water. Though gas companies often deny responsibility for the pollution, the state has imposed more stringent well-construction standards designed to prevent stray gas from polluting groundwater.

Dimock’s long quest for clean water may finally be reaching a critical stage.

After a series of false starts, Cabot, one of the largest drillers in the Marcellus, said it has met the state’s Oct. 17 deadline to restore or replace Dimock’s water supply, installing treatment systems in some houses that have removed the methane.

Residents who have filed suit against Cabot disagree, saying their water is still tainted and unusable. Another homeowner claims the $30,000 treatment system that Cabot put in failed to work.

Ultimately, it will fall to the Pennsylvania Department of Environmental Protection to decide whether Cabot has fulfilled its obligation to the residents, whose story was highlighted in last year’s Oscar-nominated documentary “Gasland.”

If regulators sign off, the company plans to resume work on a dozen gas wells in Dimock.

And, in a move sure to infuriate the residents, it will also stop paying for water deliveries to the Carters and several others whose wells were tainted with methane and, some say, toxic chemicals.

It’s not clear how DEP will respond to Cabot’s bid to restart operations, but spokeswoman Katherine Gresh said the agency is not under any deadline.

“DEP will continue to require Cabot to do this work until we are satisfied that the methane migration problem has ceased, regardless of how long it takes,” she said via email.

Despite company assurances of clean water, testing reveals that methane persists in Dimock’s aquifer — though it remains to be seen whether that alone will thwart Cabot from drilling again.

A Cabot contractor who sampled the water in mid-September found a high level of gas in the enclosed space of a water well owned by Craig Sautner, who is among the plaintiffs suing Cabot. DEP test results indicate that five more homes had levels of dissolved methane that exceeded the standard set by a December 2010 agreement between DEP and Cabot — the same agreement whose conditions Cabot says it has met.

The latest results, Sautner said, prove that nothing has changed.

“I don’t know why Cabot says there aren’t any problems in Dimock,” said Sautner, 58. “If they’re going to say that our water’s fine, I want them to be the first guinea pigs and drink it. Nice, big, tall glass of water.”

Cabot characterized the mid-September methane spike at Sautner’s house as an anomaly and said the big picture is that Dimock residents who accepted a treatment system from the company enjoy methane-free water.

“The water is clean for the families inside that area,” said Cabot spokesman George Stark.

Questions also remain about the integrity of gas wells that Cabot has already drilled.

As recently as May, DEP said nearly half of Cabot’s wells in the Dimock area — 20 of 43 — continued to leak methane, including 14 that DEP said were of the “most concern.” In a letter obtained by The Associated Press, a DEP official wrote to Cabot that the leaking wells indicate faulty construction and that Cabot had “yet to achieve full compliance” with DEP mandates.

Cabot disagreed with DEP’s assertions about its gas wells, and has been supplying documentation to the agency showing that all the wells are safe, Stark said.

Some Dimock residents say their water wells were fouled not only with methane that DEP said migrated from improperly cemented Cabot gas wells, but possibly with toxic chemicals commonly used in the drilling process known as hydraulic fracturing or “fracking.”

The company denied responsibility, saying it doesn’t use the chemicals that a consultant working for the plaintiffs found in the wells last year. Cabot suggested a nearby auto repair shop was to blame.

The problems in Dimock, about 20 miles south of the New York state line, first arose in the fall of 2008, a month after Cabot started drilling in the area. The water that came out of residents’ faucets suddenly became cloudy, foamy and discolored. Homeowners, all of whom had leased their land to Cabot, said the water made them sick with symptoms that included vomiting, dizziness and skin rashes.

One of the water wells exploded on New Year’s Day 2009, prompting a state investigation that found Cabot had allowed combustible gas to escape into the region’s groundwater supplies, contaminating at least 18 residential water wells.

Cabot asserts the methane in the residents’ wells is naturally occurring and denies polluting the water — with methane or anything else — even though DEP has said its tests confirmed the gas migrated from Cabot’s wells.

The company has plenty of support in Dimock and the rest of Susquehanna County. Many homeowners living in the moratorium area are anxious for Cabot to start drilling again so they can begin receiving royalties on the land they have leased to the company.

Jean Carter, who lives a few hundred feet from a pair of gas wells, said she and her husband have spent countless hours worrying about the water. (Cabot asserts their supply is fine, pointing to test results that show an insignificant level of dissolved methane in the Carters’ well water.)

Pa. issues air pollution rules for gas drilling

www.timesleader.com/news/Pa-issues-air-pollution-rules-for-gas-drilling.html

HARRISBURG, Pa. (AP) — Pennsylvania state environmental regulators will follow new guidelines endorsed by a natural gas industry group for deciding how to group together facilities such as wells, dehydrators and compressors when enforcing air pollution standards.

The Department of Environmental Protection issued the new guidelines Wednesday and opened them up for public comment until Nov. 21.

The Citizens Voice of Wilkes-Barre reports (http://bit.ly/q4a4KE) that the industry group, Marcellus Shale Coalition, last year urged the state not to group air pollution sources that are not contiguous or adjacent, even if they’re connected by pipelines.

Instead, it recommended a quarter-mile rule that several other states follow and which the Pennsylvania DEP wants to follow.

The new guidelines take effect immediately, but are considered interim for now.

WVU Professor: Methane Already in Groundwater

Researcher looks for causes of contamination

Those who believe their drinking water wells may be contaminated with methane released by natural gas fracking may be wrong, according to a West Virginia University professor.

“The source of methane gas can range from active or inactive deep coal mines, landfills, gas storage fields or microbial gas generated in a shallow subsurface,” said assistant professor Shikha Sharma, noting that dissolved methane gas already exists in groundwater where there is no shale gas drilling.

“As a scientist, it is my job to stay focused on the scientific perspective of this study while staying neutral on the political and social issues associated with it,” she added.

In the midst of a study on the origins of methane gas in the Monongahela River watershed and other areas of this region, Sharma stops short of saying that fracking, or hydraulic fracturing of the shale, absolutely does not release methane into groundwater.

“Depending on how and where this methane is formed, it can have very different C and H isotope signatures. This gives us the ability to know if it comes from hydrofracking releases or some other source,” she said.

Fracking occurs after companies finish the drilling portion of natural gas development. Millions of gallons of water, sand and chemicals are pumped more than a mile into the ground at high pressure in order to shatter the rock, thereby releasing the gas.

Last year, Marshall County resident Jeremiah Magers believed fracking by those working for Chesapeake Energy caused his drinking water well to become contaminated with methane.

Chesapeake officials said they collected samples from Magers’ water source. They informed him that dissolved methane gas was detected in his water sample, but that methane gas may be generated from various sources.

Earlier this year, however, the Pennsylvania Department of Environmental Protection fined Chesapeake $900,000 for apparently causing methane to be released into private water wells in the northeastern portion of the state, near New York. Environmental department officials said improper well casing and cementing by Chesapeake in shallow zones allowed methane to migrate into groundwater, thus polluting the drinking water supply. The fines included a $700,000 civil penalty and a $200,000 deposit into the Keystone State’s well plugging fund.

With the jury still out on whether fracking can release methane into groundwater, Sharma continues her study. It is being funded by a $25,000 grant from the U.S. Geological Survey, provided through the West Virginia Water Research Institute. This money allows Sharma and her graduate student, Michon Mulder, to gather and test water samples from groundwater wells in the Monongahela River watershed.

The study will allow the researchers to construct a picture of existing methane gas sources in the area, which could then be used to identify dissolved methane releases associated with Marcellus Shale gas drilling.

“There are some concerns associated with higher levels of dissolved methane,” said Sharma. “The levels of dissolved methane higher than 28 milligrams per liter are considered potentially flammable. Because dissolved methane already exists in some of our samples, we need to figure out where the actual sources of this dissolved methane gas are located.

“It is important to understand exactly how much methane exists in the groundwater now and what sources it comes from, so that unbiased decisions can be made regarding the potential and real impacts of hydrofracking on our water sources in the future,” she added.

Delaware River basin gas drilling meeting delayed

Posted on Sat, Oct. 8, 2011

The Delaware River Basin Commission on Friday postponed until Nov. 21 a meeting to consider regulations that would allow natural gas drilling in the basin. The new date is a month later than planned.
The commission, a federal and interstate agency, oversees the basin, which provides drinking water for 15 million people, including Philadelphia and some suburbs. It has put a moratorium on drilling until rules can be adopted.

The commission said it needed more time to prepare for the meeting, expected to be the site of a major protest.

Regulations were proposed in December, and by the time a public-comment period ended in April, the commission had received 69,000 submissions.

Some commission members had pushed for swift action. The New Jersey representative threatened to withhold state funding of the agency if it did not act at its September meeting.

But shortly before the September meeting, the commission announced it could not finish the job in time. A special meeting was announced for Oct. 21.

The commission says it’s still not ready. “Additional time is necessary to complete the ongoing process,” a release issued Friday said.

Other members of the commission are Pennsylvania, New York, Delaware, and the federal government, represented by the Army Corps of Engineers.

The gas-rich Marcellus Shale formation underlies the upper portion of the river basin. But the river and many tributaries there are under special protection because of their high water quality.

Critics have been angered by the possibility the commission would present revised regulations and vote on them at the same meeting.

The commission says the postponement will allow it to publish the modified regulations on its website on Nov. 7, two weeks before the expected vote.

No public comment will be taken at the meeting, the release said.

In August, environmental groups filed a federal lawsuit contending that the commission should not adopt any regulations until a broad cumulative-impact study is completed. New York, which will not allow drilling until state regulations are adopted, filed a similar action in June.

New Jersey State Police confirmed that a permit had been issued for protesters to demonstrate outside the meeting. The permit application estimated 500 people would participate.

Within the last few days, Facebook and Twitter accounts for “OccupyDRBC” – an offshoot of the Occupy Wall Street protests – have been formed.

The Nov. 21 meeting will run from 10 a.m. to noon at the War Memorial in Trenton
