Water Problems from Drilling are Widespread in Pennsylvania

By Abrahm Lustgarten, ProPublica

When methane began bubbling out of kitchen taps near a gas drilling site in Pennsylvania last winter, a state regulator described the problem as “an anomaly.” But at the time he made that statement to ProPublica, that same official was investigating a similar case affecting more than a dozen homes near gas wells halfway across the state.

In fact, methane related to the natural gas industry has contaminated water wells in at least seven Pennsylvania counties since 2004 and is common enough that the state hired a full-time inspector dedicated to the issue in 2006. In one case, methane was detected in water sampled over 15 square miles. In another, a methane leak led to an explosion that killed a couple and their 17-month-old grandson.

Methane is the largest component of natural gas. Since it evaporates out of drinking water, it is not considered toxic, but in the air it can lead to explosions. When methane is found in water supplies, it can also signal that deeply drilled gas wells are linked with drinking water systems.

In many cases the methane seepage comes from thousands of old abandoned gas wells that riddle Pennsylvania’s geology, state inspectors say. But other cases, including several this year and the 2004 disaster that left three people dead, were linked to problems with newly drilled, active natural gas wells.

The issue came to the forefront in January when methane was found in the water at 16 homes in the small town of Dimock, in northeastern Pennsylvania. State officials cited Cabot Oil & Gas for several violations they say allowed the gas to seep out of the well structures and into water supplies there. The Department of Environmental Protection asked the company to encase its lower well pipes completely in concrete — a process known in the industry as “cementing” — and assured the public that the contamination in Dimock was rare.

But according to a department spokeswoman, there have been at least 52 separate cases of what the state calls “methane migration” in the past five years. In two of the 2009 cases, regulators responded to complaints from more than 32 households and asked gas companies to supply clean water to at least a dozen homes with contaminated wells.

An undated report from the Pittsburgh Geological Society posted to the DEP’s Web site makes it clear that old wells and new drilling can lead to stray gas problems. “Although it rarely makes headlines,” the report reads, “damage or threats caused by gas migration is a common problem in Western Pennsylvania.”

The case Lobins was investigating at the same time as the Dimock case concerned a string of problems in Bradford, a rural town 200 miles west of Dimock along the state’s northern border. Shortly after a contractor for Schreiner Oil and Gas drilled several dozen wells in the area last spring, residents began complaining of murky and foul-smelling tap water. When the DEP investigated, it found methane in three water wells and metals in six others. It asked Schreiner to supply water to eight homes, and the company has begun installing water treatment systems at each house. While no new gas wells have been drilled in the Bradford area, according to the DEP, the existing ones continue to operate.

Michael Schreiner, Schreiner’s president, declined to comment for this article.

Lobins said the problems in Bradford — as in many of the contamination cases across the state — stem from a bad cementing job around the core of the well. In most gas drilling, the well pipe is encased in layers of concrete to keep it isolated from surrounding groundwater. The concrete also contains the enormous pressure exerted on the system during the process of hydraulic fracturing, which pumps water, sand and chemicals to the well bottom to break up rock.

Obama May Reverse Bush on Perchlorate Levels in Drinking Water

By Amy Littlefield

The Obama administration may be poised to reverse another Bush administration decision on toxic chemicals.

Under President Bush in 2008, the Environment Protection Agency decided not to regulate perchlorate, a chemical used to make rocket fuel that has been found in drinking water and has been linked to thyroid hormone disruption in young children. Now, it looks like the agency is reconsidering that stance.

In California, perchlorate used in manufacturing has seeped into groundwater. High levels of the chemical in drinking water has caused alarm in Rialto and Santa Clarita. The chemical has also turned up in tainted lettuce. In the absence of federal regulations, California moved to set state standards for perchlorate in drinking water in 2006. Massachusetts was the only other state with an enforceable standard on the chemical.

That same year, the EPA drew a response from scientists at its the Office of Environmental Health Hazard Assessment, who said the agency’s recommended standard on perchlorate failed to protect infants and children.

Now, EPA Administrator Lisa P. Jackson has said the organization will take another look at the chemical and accept public comments.

“It is critically important to protect sensitive populations, particularly infants and young children, from perchlorate in drinking water,” Jackson said. “As we re- re-evaluate the science around perchlorate, we will seek public input before making a regulatory determination based on the best science.”

The chemical is used to make fireworks, flares and rocket propellant.

Exxon Liable for Tainted Water in Queens

By Mireya Navarro, New York Times

Lawyers for New York City are trying to convince a jury in a federal trial that Exxon Mobil knew that an additive that it used in gasoline would contaminate groundwater.

The trial, which began on Tuesday before Judge Shira A. Scheindlin of United States District Court in Manhattan, is one of hundreds of cases that have been presented around the country against oil companies over the additive, M.T.B.E., a chemical compound that replaced lead in gasoline as an octane enhancer. Such enhancers boost engine performance and help prevent knocking.

New York City’s case against Exxon Mobil arose from the contamination of groundwater wells in Jamaica, Queens, that are designated as part of a backup system for drinking water in emergencies or droughts. In 2003, the city sued 23 oil companies over the contamination; it has reached settlements with 22, for a combined $15 million.

The Environmental Protection Agency says that even low levels of M.T.B.E. can make water undrinkable because of its taste and odor. While researchers have limited data on its health effects on humans, it is considered a carcinogen in high doses in animals.

Like ethanol, M.T.B.E., methyl tert-butyl ether, helps gasoline burn more cleanly and reduces tailpipe emissions. But it is also highly soluble in water, and fuel leaks from storage tanks and other sources have contaminated groundwater that is often a source of drinking water.

Twenty-five states, including New York, have restricted or banned M.T.B.E.

In opening statements on Tuesday, the lawyer for the city, Victor Sher, argued that Exxon, which started using M.B.T.E. in the 1980s, ignored evidence from its own scientists of a strong risk of groundwater contamination should the compound be added to gasoline. Mr. Sher argued that the company could have used ethanol, a more expensive octane enhancer that does not pose the same hazard.

Mr. Sher said 39 of 68 wells in Queens show M.T.B.E. contamination. But the focus of the trial is five contaminated wells that can yield about 10 million gallons a day to supplement water sources in cases of failure in the upstate reservoir system that provides New York City’s drinking water. City officials say a $250 million treatment facility would have to be built to make the water in the wells drinkable.

The company says that the wells are contaminated by other industry in the area. It adds that the city does not intend to build the treatment plant and has other projects under way to provide other backup sources of water.

The jury must rule on several elements of the case, including whether the city intends to build the treatment plant, the extent of M.T.B.E. contamination and the size of any punitive damages.

Union Pacific to Pay for Water Act Violations

By John Boyd, Journal of Commerce Online

Union Pacific Railroad will pay civil penalties of $800,000 and is restoring some Nevada stream areas at an estimated cost of $31 million, the Department of Justice said, to settle alleged Clean Water Act violations in 2005.

In January 2005, the government said, UP’s tracks in the Clover Creek and Meadow Valley Wash areas “sustained significant damage following a flood in southern Nevada” and the railroad “made time-critical actions to repair damage.”

But Justice said “UP also conducted extensive non-emergency construction and stream alteration work without obtaining the required Clean Water Act permits, which could have minimized and compensated for the damage to the streams.”

That work included building “massive structures to control stream flows, such as dikes, berms, levees and diversions within the stream systems,” some up to 15 feet high and as much as thousands of feet in length.

The proposed decree said “Union Pacific has already performed substantial removal, restoration, and re-vegetation work at many sites.” It also said “nothing in this consent decree shall constitute or be construed as an admission of liability or wrongdoing by Union Pacific.”

John C. Cruden, acting assistant attorney general for the department’s Environment and Natural Resources Division, said work the railroad agreed to undertake in the settlement “will restore Clover Creek and Meadow Valley Wash.”

Kush said “most of the requested work is complete.” Justice said UP agreed to restore 122 acres of mountain-desert streams and wetlands, in 21 sections in Clark and Lincoln Counties, Nev.

California Adds Delta Tunnel to List of Possible Water Solutions

By Collin Sullivan of Greenwire

SAN FRANCISCO — California officials are studying whether a 35-mile tunnel under the Sacramento-San Joaquin River Delta might help solve some of the state’s water supply problems.

Teresa Engstrom, chief of the delta engineering branch at the California Department of Water Resources, confirmed that the agency is conducting feasibility studies on an “all tunnel” option that would route water under the Bay Delta from rivers and reservoirs to the north of Sacramento to farms in the south.

The idea to build a tunnel sprang from a handful of public workshops the department held recently on how to approach California’s long-running fight over water rights in the northern part of the state. A tunnel, she said, could theoretically offer a way out of the vexing maze of water supply, endangered species and farming issues facing the state.

“We had a lot of comments that said, ‘Why don’t you go under?’” Engstrom said. “So we thought we would take a look.”

Engstrom stressed that the all-tunnel option has no more weight at this point than competing ideas to build a canal around the delta or new levees along the water’s current route through the middle of the delta region. All are under consideration.

DWR engineers conducting environmental and geotechnical studies expect to have a draft environmental report completed by the end of the year on all three proposals, Engstrom said. A final public draft would then be ready next year.

The new wrinkle comes as lawmakers, farmers, commercial fishers and environmentalists continue to bicker over whether to build major new infrastructure to both protect endangered fish and improve water deliveries to farms in the Central Valley. Pumping through the region is currently restricted to protect endangered delta smelt and salmon, much to the ire of struggling farmers.

Jonas Minton, water policy adviser for the Planning and Conservation League, called the tunnel proposal and the council bad ideas. He estimated that such a tunnel would likely stretch beyond 50 miles, making it “longer than the Chunnel connecting England with France.”

“The Department of Water Resources says it has no idea how much the tunnel would cost,” added Minton, guessing it would easily surpass the $13 billion spent 15 years ago to build the tunnel connecting France and England.
