Study finds water in Pennsylvania town contaminated with methane and fracking toxins

By Christine Shearer / TruthOut

Although the Environmental Protection Agency (EPA) Region 3 issued a statement last week that its preliminary tests of water samples near drilling and fracking sites in the Pennsylvania town of Dimock showed no health concerns, the group Water Defense and “Gasland” director Josh Fox went to Dimock to look at the EPA summaries themselves, which they say do report high levels of explosive methane, heavy metals and hazardous chemicals. The issue is raising renewed controversy over the increasing growth of unconventional gas drilling and fracking and the uncertainty around health and safety regulations.

By the 2000s, it was starting to look like the reign of coal in providing over half of US electricity was ending. Community opposition and changing economic conditions turned the tide on most of the over 150 new coal plants proposed by the George W. Bush administration. And the EPA was being pressured to implement or update a suite of overdue coal regulations, including coal waste, mercury, water pollution and greenhouse gases, among others, making coal less commercially competitive compared to other energy alternatives.

While some looked hopefully to renewable energy to fill in the gap, industry developments in horizontal drilling and hydraulic fracturing were ushering in what appeared to be a new era for “unconventional” natural gas. Suddenly, the race was on for shale gas and oil deep underground. Homeowners and cities across the US agreed to drilling leases on their land, spurred on by the promise of low impact and high royalties. Plus, gas releases fewer pollutants when burned than coal, including about half the carbon dioxide emissions, making it easy to portray as the ideal bridge to a clean energy future.

Although the deep drilling process was in many ways new – particularly the cocktail of chemicals, sand and water used to break up the shale and release the gas in what has become known as “fracking” – gas drillers received exemptions from seven federal regulations that apply to other industries, including the Clean Water Act; the Clean Air Act; the Superfund law; and, most notoriously, the Safe Drinking Water Act, due to the “Halliburton loophole” in the 2005 Energy Policy Act. Regulation and oversight were largely left to individual states, many of which were already overburdened, underfunded and under staffed.

By 2009, there were more than 493,000 active natural gas wells across 32 states in the US, almost double the number in 1990. And around 90 percent have used fracking to get more gas flowing, according to the drilling industry.

Fracking industry has spent $726 million on lobbying since 2001

By Environment News Service

A natural gas drilling rush is on in rural North Dakota. And with it, residents are reporting growing numbers of respiratory ailments, skin lesions, blood oozing from eyes, and the deaths of livestock and pets.

Elsewhere, residents of Texas, Pennsylvania, Colorado, Wyoming and other states who thought they’d hit the lottery by signing natural gas drilling leases have watched their drinking water turn noxious: slick, brown, foamy, flammable.

In December, for the first time, federal regulators scientifically linked hydraulic fracturing, or fracking, to the contamination of an aquifer, refuting repeated industry claims that the practice does not pollute drinking water.

It happened in the rural ranching community of Pavillion, Wyoming, an area riddled with 162 natural gas wells dug between 1990 and 2006. Despite a decade of complaints from residents that their reeking water was undrinkable – and that many suffered from nerve damage, asthma, heart trouble and other health problems – state officials did nothing.

Finally the EPA stepped in, launching a three-year study running from 2008 to 2011.

In its report, the EPA identified numerous fracking chemicals in Pavillion’s water. Cancer-causing benzene was found at 50 times safe levels, along with other hazardous chemicals, methane, diesel fuel, and toxic metals – in both groundwater and deep wells.

Now, across the country in Pennsylvania, the EPA is testing drinking water in 61 locations in Susquehanna County for possible fracking-related contamination.

Nationwide, residents living near fracked gas wells have filed over 1,000 complaints of tainted water, severe illnesses, livestock deaths, and fish kills. Complaints, sometimes involving hundreds of households, have risen in tandem with a veritable gold rush of new natural gas wells – now numbering about 493,000 across 31 states.

This month’s hearings on the EPA’s Pavillion report, led by the House subcommittee on Energy and the Environment, have been contentious, with pro-drilling politicians and industry representatives attacking its conclusions.

“The EPA is trying to go after fracking everywhere they can,” said subcommittee chairman Andy Harris, a Maryland Republican. “They’ve had absolutely no proof that fracking had polluted drinking water, that I know of.”

Both he and industry spokesmen implied that the media had created a poorly-informed frenzy, spreading fear and mistrust of fracking.

However, James Martin, the EPA’s regional administrator for the West, testified that cement casings that should have protected drinking water were weak or missing – a possible source of contamination.

Other witnesses, including Dr. Bernard Goldstein, of the University of Pittsburgh’s Graduate School of Public Health, argued that the public should be concerned, noting that policy makers lack adequate information to protect public health.

Still, the fracking industry goes virtually unregulated. Why? The answer is money.

The oil and gas industry has reaped billions in profits from fracking. And since 1990, they’ve pumped $238.7 million into gubernatorial and Congressional election campaigns to persuade lawmakers that fracking is safe, which has effectively blocked federal regulation.

Republican candidates received at least three times more cash than Democratic candidates. Fracking industry spending especially targeted oversight – members of the House Energy and Commerce Committee and the Senate Committee on Environment and Public Works.

Top Congressional recipients include Joe Barton and John Cornyn, both Texas Republicans, with contributions of $514,945 and $417,556 respectively; Lisa Murkowski, an Alaska Republican, who received $372,450; and Tim Murphy, a Pennsylvania Republican who took in $275,499.

James Inhofe, an Oklahoma Republican, who accepted $357,788, claimed the EPA study was “not based on sound science but rather on political science.”

The industry spent an additional $726 million on lobbying from 2001.

Pennsylvania Governor Tom Corbett also received hefty election support – $361,207. Corbett has signaled willingness to sign a fracking bill passed by the state Senate this month that offers huge benefits to natural gas drillers and essentially prevents municipalities and environmentalists from taking action against the location of wells.

Today, only four of 31 fracking states have significant drilling rules, while the gas industry is exempted from seven major federal regulations.

One of these, the “Halliburton loophole,” pushed through by former Vice-President/former Halliburton CEO Dick Cheney, exempts corporations from revealing the chemicals used in fracking fluid – bypassing the Clean Water and Safe Drinking Water Acts.

Recently, five states have adopted disclosure rules, though they still allow for “proprietary trade secrets.”

Another loophole leaves hazardous waste, including contaminated soil, water and drilling fluids, unregulated by the Resource Conservation and Recovery Act.

Still another loophole dodges the Superfund law, which requires that polluters remediate for carcinogens like benzene released into the environment – except if they come from oil or gas.

Fracking, or hydraulic fracturing, which was invented by Halliburton in the 1940s, injects water, sand and chemicals into the ground at high pressure, blasting apart shale bedrock to release natural gas. However, industry’s reassurance that fracking is an old technology with a proven safety record is misleading.

Modern fracking is drastically different, using new chemical mixtures and millions rather than thousands of gallons of water injected at far higher pressure. It takes between one and 10 million gallons of water to frack one well.

Last week it was revealed that one well in Carrollton, Ohio, required 969,024 pounds (484.5 tons) of chemical additives, 5,066 tons of sand and 10.5 million gallons of water. Up to 40 percent of that water returns to the surface, carrying toxic drilling chemicals, high levels of salts, and sometimes, naturally-occurring radioactive material.

A 1990 industry study concluded that radium in drilling wastewater dumped off the Louisiana coast posed “potentially significant risks” of cancer for people who regularly eat fish from those waters.

Most fracking water remains underground, potentially polluting aquifers and drinking water. Streams and groundwater can be contaminated by spills, surface wastewater pits, and by millions of tons of chemical-laden dirt removed during the drilling process. Sewage treatment plants aren’t equipped to treat chemicals or radioactivity in frackwater that could end up in drinking water.

Today, 65 probable fracking chemicals are federally listed as hazardous. Many others remain unstudied and unregulated, making it impossible to assess the effects on water resources.

EPA documents note that some “cause kidney, liver, heart, blood, and brain damage through prolonged or repeated exposure,” and that fracking fluid migrates over unpredictable distances through different rock layers.

Last August, a national association of pediatricians published concerns that children are more susceptible to fracking chemical exposure than adults.

Air pollution in Southern California likely to kill up to 360,000 people

By Bernice Yeung / Huffington Post

Southern Californians are among those at highest risk of death due to air pollution, according to recent U.S. Environmental Protection Agency research published in the journal Risk Analysis.

The study, published last month, was conducted to “provide insight to the size and location of public health risks associated with recent levels of fine particles and ozone, allowing decision-makers to better target air quality policies,” the federal agency said in a statement responding to California Watch inquiries.

“While overall levels of fine particles and ozone have declined significantly in the past two decades, these two pollutants still pose a burden to public health,” the EPA statement said.

The study examined air pollution exposure based on 2005 air quality levels and projected there could be between 130,000 and 360,000 premature deaths among adults in coming years. The 2005 data was the best available for analyzing fine particulates and ozone, the EPA said. Among vulnerable populations like children, the EPA also estimates that fine particulate matter and ozone results in millions of cases of respiratory symptoms, asthma and school absences, as well as hundreds of thousands of cases of acute bronchitis and emergency room visits.

The analysis also found that Southern Californians and residents of the industrial Midwest experience the highest exposure to fine particulate matter, which has been found to exacerbate respiratory illnesses and increase heart attacks, according to the Centers for Disease Control and Prevention.

Among the most populated areas of the country, Los Angeles had the highest estimated rate of deaths attributable to air pollution, at nearly 10 percent; San Jose had the lowest at 3.5 percent.

The Bay Area Air Quality Management District conducted a similar risk assessment last year and found that about 1,700 premature deaths can be attributed to fine particulate matter in the Bay Area each year, which is about 3.8 percent of all deaths.

Particulate matter is made up of extremely small particles and liquid droplets that are 2.5 micrometers in diameter or smaller – which means they have a width 30 times smaller than a human hair. Common sources of fine particulate matter, often referred to as PM 2.5, are forest fires and emissions from power plants, industrial sources and cars. Unhealthy forms of ozone are created when nitrogen oxides (NOx) and volatile organic compounds (VOCs) react in the presence of sunlight; ozone is typically linked to byproducts from industrial facilities and electric utilities, car exhaust, gas vapors and chemical solvents.

Local air districts in Southern California and the Bay Area have attempted to limit fine particulate matter and ozone emissions through Spare the Air days by regulating wood burning and offering financial incentives to businesses to phase out the use of diesel engines.

Public health advocates say that the EPA study illustrates the importance of improving air quality and that these types of studies on the risks of air pollution have been used to determine federal regulations and inform local clean air plans.

“One of the hardest things to explain to the public is that while the air is cleaner, we continue to find that we have underestimated the health effects of breathing in air pollution,” said Joe Lyou, president and CEO of the Coalition for Clean Air and a governing board member of the South Coast Air Quality Management District. “Yes, we have made significant accomplishments, but we still have a long way to go. The public needs to understand that this is a life-and-death situation.”

What Killed Dunkard Creek? Residents in Pennsylvania and West Virginia Say Fracking

By Adam Federman

On August 27, 2009, Dan Cincotta, a fisheries biologist with West Virginia’s Department of Natural Resources, was conducting a routine inventory of Dunkard Creek, a small river that runs through West Virginia and southwestern Pennsylvania. He was accompanied by a consultant and an environmental engineer from the state’s largest coal and gas company, Consol Energy, which operates a coalmine, Blacksville #2, just outside of Wana, West Virginia. Cincotta was supposed to do electro-fish surveys, whereby the fish are temporarily stunned in order to assess populations, and to take a series of conductivity readings – a basic measure of how much salt is dissolved in water.

When his first reading measured 20,000 micro siemens per centimeter squared (µS/cm), Cincotta thought his equipment was broken; he had never seen readings above 5,000. The Consol consultant took her own reading in the same location but farther from the riverbank. It registered 40,000 µS/cm. Still in disbelief, Cincotta says, “we wandered upstream and found [Consol’s mining] discharge. And in the discharge alone, straight out of the pipe our equipment registered over 50,000 µS/cm,” roughly the equivalent of seawater. Untreated acid mine discharges typically have conductance values of between 1,000 and 1,500 µS/cm.

The following day, a Friday, Cincotta sent an email to the US Environmental Protection Agency (EPA) field office in West Virginia alerting them to the extraordinarily high conductivity levels. Then, over the weekend, the reports of dead fish began. During the next month about 22,000 fish washed ashore (some estimates say as many as 65,000 died). At least 14 species of freshwater mussels – the river’s entire population – were destroyed, wiping out nearly every aquatic species along a 35-mile stretch of Dunkard Creek. “That’s the ultimate tragedy,” says Frank Jernejcic, a fisheries biologist with the West Virginia Department of Natural Resources. “Fish will come back, we can get the fish back. The mussels are a generational thing.”

The scene was horrific: Many of the fish were bleeding from the gills and covered in mucous; mud puppies, a kind of gilled salamander that lives underwater, had tried to escape by crawling onto nearby rocks; three-foot long muskies washed up along the riverbanks. The die-off marked one of the worst ecological disasters in the region’s history.

“Unless you have actually seen a fish kill, it’s one of the most devastating things that you can imagine,” says Verna Presley, a retired teacher who lives on the creek. “Because you don’t think of the sound of a stream until it’s dead and it’s just the eeriest silence that you can imagine. Everything right down to the insects was killed.”

A nearly three-month-long investigation by state and federal regulators eventually tied the kill to an invasive algae species known as golden algae (Prymnesium parvum). Yet golden algae offered only a partial explanation for the disaster. It may have been the immediate reason for the kill, but it wasn’t the underlying cause. The algae itself cannot survive in freshwater; it thrives only in marine-like environments. Somehow, a freshwater, inland ecosystem had become saline enough for the algae to grow and multiply.

How did this Appalachian stream become so salty? There is no single answer, no smoking gun. The contaminated water might have come from acid mine drainage discharges – outflow of wastewater from nearby coalmines, which has been occurring for decades. It might also be tied to natural gas drilling in the Marcellus Shale, a relatively new industry in the region. Or perhaps it was a toxic cocktail of both.

The complexity of the disaster has allowed the company most likely responsible for destroying the stream, Consol Energy, to deny wrongdoing. “Working with renowned biologists, Consol Energy determined its operations were not the cause” of the fish kill, the company said in a 2010 press release. Still, Consol recently reached an agreement with the EPA to pay $5.5 million in civil penalties and construct a brine water treatment plant by 2013.

The EPA and state regulatory agencies have concluded that acid mine drainage from Consul’s coalmine led to the algae bloom. But many area residents, some local conservation officers, and the lead EPA investigator on the case have cast doubt on that assumption. They believe the stresses of coal bed methane extraction and hydraulic fracturing, or fracking, in the Marcellus Shale also contributed to the stream’s worsening condition. They argue that acid mine drainage alone doesn’t explain the changes that occurred in the stream’s composition and that illegal dumping of wastewater and water withdrawals from Dunkard Creek must have played some part in the algae bloom.

“Because you don’t think of the sound of a stream until it’s dead and it’s just the eeriest silence that you can imagine. Everything right down to the insects was killed.”

The fish kill at Dunkard Creek points to a systemic threat that could jeopardize the watersheds of an entire region. As unconventional shale gas production expands throughout the Northeast (conservative estimates are that 60,000 wells will be drilled in Pennsylvania alone over the next two decades) its rivers and streams may be forced to absorb increasingly large volumes of exceptionally salty water – water ten to twenty times more saline than seawater. “Produced water,” as it is referred to by the industry, is a mix of fracking chemicals, water, and dissolved shale formation solids; it represents the largest volume byproduct of oil and gas exploration and production in the United States.

Pennsylvania officials, at least, seem to recognize that improper disposal of produced water would lead to an environmental and public health fiasco. State regulators recently said that municipal treatment plants would no longer be permitted to accept Marcellus Shale wastewater, a major policy reversal. What the state plans to do with the billions of gallons of wastewater created during the drilling process remains unclear.

Dunkard Creek snakes along the Pennsylvania-West Virginia border and eventually empties into the Monongahela River, which flows north to Pittsburgh. The creek was long considered one of the most diverse streams in the Monongahela watershed. Known for its muskellunge fishing, it also supported an unusually rich population of freshwater mussels. The area is also dotted with coalmines, many of which discharge acid drainage directly into the creek and its tributaries. Massive underground mine pools must be continuously pumped either by the companies that own them or, if they’ve been abandoned, by the state. Billions of gallons of treated wastewater are discharged into the Monongahela River basin annually.

In recent years, coal bed methane extraction – the absorption of natural gas from coal seams – along with natural gas hydraulic fracturing in the Marcellus Shale have placed further stresses on the river in the form of water withdrawals and wastewater disposal. In Greene County, through which Dunkard Creek runs, more than 250 natural gas wells have been drilled in just a few years. Consol, the largest producer of coal from underground mines in the United States, has described the fossil fuel-rich area as “the continental US equivalent of Prudhoe Bay.” Like Alaska’s Prudhoe Bay, the region has begun to experience the impacts of large-scale industrial development and resource extraction.

A month after the fish kill, state and federal officials pointed to acid mine drainage – Consol had been discharging the waste directly into Dunkard Creek for decades – as the cause of the algae bloom and fish kill. Found worldwide in estuarine waters, golden algae was first reported in the United States, in Texas, in 1985. Since then it has killed more than 12 million fish in Texas and has slowly spread to several other river basins. The algae responds to certain stressed environments by releasing a toxin that ruptures the tissue cells in the mouths and gills of fish, depriving them of oxygen and causing them to suffocate – hence the desperate attempts of the fish and mudpuppies to escape the river. Until the Dunkard Creek fish kill, however, the algae had never been detected north of the Mason-Dixon Line.

“When the fish kill first happened, we in the research community got a lot of calls,” says Jeanne VanBriesen, director of the Center for Water Quality at Carnegie Mellon University. “‘Who do you know who knows anything about golden algae?’ And we all said the same thing: ‘In Pennsylvania why would anyone know anything about golden algae? You have to go to Texas or Florida because it hadn’t been seen here.’” Golden algae has now been found in several waterways in Pennsylvania and West Virginia.

How the algae ended up in Dunkard Creek may never be known. Dr. David Hambright, a professor of zoology at the University of Oklahoma, has analyzed samples of golden algae from Dunkard Creek and is investigating the phylogenetic relationships between different strains. “It’s never going to be possible to say, okay, it was a bucket of water on the back of a drilling truck from South Texas,” he told me. “It was very likely wind borne.” Hambright isn’t surprised that the algae has been found in Dunkard Creek. “What’s surprising,” he says, “is that they would find the habitat in which they could live.” But they did. In the case of Dunkard Creek, unusually high levels of dissolved solids, nutrient-rich water, and low flows created a kind of perfect storm for the algae’s growth.

Early assessments of the kill pointed to fracking wastewater as the source of the river’s high levels of Total Dissolved Solids (TDS) – a rough measure of salts and minerals dissolved in water. “The elevated levels of TDS and chlorides in the creek indicates oil- and gas-drilling wastewater,” West Virginia Department of Environmental Protection (DEP) spokeswoman Kathy Cosco said at the time. However, water samples taken later showed that the dominant ion in Dunkard Creek around the time of the kill was sulfate, which is typical of acid mine drainage, and not chloride (although chloride levels were also abnormally high) commonly found in fracking wastewater.

This led the Pennsylvania and West Virginia environmental agencies to conclude that the high conductivity levels that caused the algal bloom were largely the result of acid mine drainage. “There’s no evidence at this point – nor do I think there will be – that any of the problems in Dunkard Creek were related to the oil and gas industry,” says Pennsylvania DEP Southwest Regional Director Ron Schwartz. “There were a lot of different causes for it, but that wasn’t one of them,” he says. Scott Mandirola, director of West Virginia DEP’s Division of Water and Waste Management, agrees. “The Dunkard issue is mine water,” he says. “We investigated this thing from top to bottom and everything we’ve got points to the mining discharges.”

But Consol denies that it is at fault and, as part of its agreement with the EPA, has not admitted liability for the kill. “We do not believe the discharge from our mining operations caused the fish kill,” says Joe Cerenzia, PR director for the company. He points out that Consol has operated the mine for 30 years without incident. “It was the algae that did [it].” The company’s rationale – that it had discharged acid mine drainage into Dunkard Creek for 30 years without any problems – raises more questions than it answers. What, then, changed the river’s composition?

In emails obtained by The New York Times under a Freedom of Information Act request, Lou Reynolds, the lead EPA biologist on the case, wrote: “Mine discharges from those deep mines shouldn’t differ a lot from the normal mining constituents. Something has changed in the mine pools.”

The difference, many local residents speculate, was wastewater from natural gas and coal bed methane extraction. The Marcellus Shale is a sedimentary rock formation that was deposited more than 350 million years ago in a shallow inland sea. These ancient rocks contain chlorides that dissolve during the process of hydraulic fracturing. Abnormally high chloride readings in Dunkard Creek could have come from improper disposal of produced water, residents say.

In 2005 Consol Energy formed a subsidiary, CNX Gas, which specializes in coal bed methane extraction and natural gas drilling. That same year it applied for a permit to operate the Morris Run injection well – part of the abandoned Blacksville #1 coalmine – to dispose of wastewater from coal bed methane extraction. The Morris Run borehole is on the Pennsylvania side of the river, just upstream from the Blacksville #2 mine in West Virginia. CNX’s permit required the company to secure the area with a fence and monitor the cumulative volume of water injected into the well.

An EPA inspection in August 2008 found that the company was violating several provisions of the permit application. Then, in the spring of 2010, one of Consol’s primary contractors, Allan’s Waste Water Service, a wastewater hauling company, was charged with multiple counts of illegally dumping toxic waste, including Marcellus Shale-produced wastewater. According to a grand jury presentment, drivers for the company testified that they dumped drilling wastewater into the Morris Run borehole and into several tributaries of Dunkard Creek. “Drivers testified that Allan’s Waste Water was responsible for receiving, transporting, and disposing of production water from gas wells owned and operated by CNX,” the Pennsylvania Attorney General’s office noted. “According to the drivers, during the summer of 2007, CNX’s gas wells began to generate more production water than Allan’s Waste Water was capable of handling. As a result, [company owner] Shipman showed the drivers how to leave open the gas well valves and ordered them to discharge production water into the ground and/or into the nearby waterways,” including Dunkard Creek.

Before the fish kill there was a steady stream of traffic on the narrow dirt road that leads up to the borehole, local residents say. “It was 24/7 trucks going up the road to the borehole,” says Verna Presley, who lives nearby. “They even constructed areas off of the road so that one truck could pull over and another one could get past.”

Martin Niverth, who was Greene County Conservation Commissioner at the time, says that he received numerous phone calls from people living in the area complaining about the traffic on the road to the underground injection well. “There’s trucks coming and going. Well, that kind of volume, you know, what does that tell you? I know what it tells me. You know that you have Marcellus dumping going on down there.” Even Mandirola of the West Virginia DEP concurs: “A lot of Marcellus wastewater went down in that hole,” he says. “There is a separation between those two mines,” says Mandirola. “But there is seepage through the wall. I don’t think anybody really knows how much seepage is occurring, but the Morris Run borehole is right at the edge of that division.”

Presley also says that the haulers were withdrawing water from the river, presumably for use in fracking operations, which require millions of gallons of freshwater per well. “They were pumping so much out of Dunkard Creek that they just put their hoses into the water and left them there for the next truck to come and hook up and pull it out,” she says. “We literally watched the stream go down about 12 inches prior to the fish kill.”

USGS data from further downstream shows a steep decline in river flows during that period. “The decrease in flows at the end of August does look suspect,” Clinton Hittle, a hydrologist with the USGS, wrote in an email.

Niverth, whose first job was at the Blacksville #2 mine loading coal, believes that the unregulated injection of Marcellus wastewater into the Morris Run borehole, illegal dumping, and water withdrawals all contributed to the fish kill. “I fished that stream for years and years,” Niverth says, “and that’s why some of us are still very skeptical, because those mines operated for years. … Then right when the Marcellus comes in this happens. Why?”

Several months before the fish kill, the EPA was in the process of drafting a consent order to address Consol’s security violations at the injection well. But after the fish die-off the company decided to plug and abandon the well. It was still fined the maximum penalty of $157,000 for failing to secure the site, but the underground injection well was never officially linked to the kill.

Dan Cincotta, the biologist who first recorded unusually high conductivity readings on Dunkard Creek, says that salinity levels in rivers and streams in Pennsylvania and West Virginia are a growing concern. Over the last 30 years he’s sampled thousands of streams and conducted several statewide surveys. “All the streams around are much higher in conductivity than they used to be,” he says. Shale gas extraction will likely just add to the problem. Last year the Academy of Natural Sciences in Philadelphia released preliminary data from one of the few studies to look at the impact of shale gas drilling on rivers and streams. They found that TDS levels were significantly higher and biodiversity indicators reduced in streams exposed to high-density gas drilling. At the same time, billions of gallons of acid mine drainage must be disposed of annually.

“We’re at the assimilative capacity of the river,” says David Argent, a fisheries biologist at the California University of Pennsylvania who has conducted surveys on the Monongahela. “In other words, you can’t dilute any more in the Monongahela. It doesn’t matter what it is – if it’s Marcellus, if it’s mining, if it’s sewage, if it’s treated sewage, if it’s untreated sewage, we’re there. And I think it’s just a matter of what is it that’s going to tip the scale now and push us over the edge.”

In 2008, TDS levels on the Monongahela were twice as high as the historical maximum since record keeping began in the 1960s, including a period during which the river supported little or no aquatic life. That summer, during a period of low flows, there were reports of foul smelling drinking water and malfunctioning dishwashers in a residential neighborhood outside of Pittsburgh. The DEP issued an advisory warning suggesting that residents drink bottled water (the Monongahela is a source of drinking water for about one million people) and later determined that nine sewage treatment plants were discharging large volumes of Marcellus Shale-produced water into the river. An internal EPA memo obtained by The New York Times described the incident as “one of the largest failures in US history to supply clean drinking water to the public.”

One year later, the high TDS and chloride levels that led to the Dunkard Creek fish kill were detected on the Monongahela, more than 40 miles downstream, in Elizabeth, PA. “I think that was kind of the alarm cry that we needed,” Argent says. “Because I think at that point people really started to question, you know, what’s going on with the water.”
