Smelling gas one morning, a southern Pennsylvania farmer almost passed out when he went outside to check on his bellowing cows.
One of the animals did keel over, kicking its feet in spasms. A couple of days later, a calf was fighting for its life, the farmer said. It died.
Something awful is happening over the Marcellus Shale, the vast geological formation in eastern North America where energy companies are looking for natural gas.
Hydraulic fracturing, or fracking, a process for extracting gas by injecting high volumes of water and chemicals into deep wells, has sparked complaints about ruined landscapes and fouled groundwater. Increasingly there is evidence, mostly anecdotal, that animals are suffering.
A new study by veterinarian Michelle Bamberger and Robert Oswald, a professor of veterinary medicine at Cornell University, chronicles case studies of dozens of farmers and pet owners in six states over the Marcellus Shale.
Their findings, published in “New Solutions: A Journal of Environmental and Occupational Health Policy,” are a harrowing account of sudden deaths of cattle, as well as reproductive and neurological problems in horses, cats, dogs and other animals.
The Pennsylvania farmers I spoke with have lost cows, calves, a horse, a couple dozen chickens. Many of the animals succumb in the same way: seizure-like symptoms, gasping for breath and a quick wasting away. A Rottweiler and a Dalmatian also fell ill and died.
Crops Lost
These farmers are getting out of the beef business, in part over concern that their animals will become delivery systems for contaminants.
An organic farmer from southeast Ohio told me he has abandoned his cash crop, ginseng, for now, concerned that contaminants would enter his product. He began noticing changes around his 20-acre property in 2007, when a fracking operation began dumping wastewater nearby. He lost quite a few deer that were drawn to the brine and antifreeze in the fluid.
Energy representatives dismiss the veterinarians’ study. They say that health indicators have actually improved in areas with shale development.
“The paper is little more than a collection of personal testimonials that cannot be independently assessed or verified,” says Steve Everley, a spokesman for industry group Energy in Depth. “The paper is full of bold assertions about oil and gas development, but empty of any facts or scientific evidence to support those opinions.”
Causal Link
Establishing a causal link between fracking and specific health threats is tricky. Energy companies are not required to disclose the composition of fracking fluids for proprietary reasons, so they don’t.
Like a lot of people who live near fracking operations, many of the farmers I interviewed are in litigation with an energy company and wish to remain anonymous.
“We don’t know what the chemicals are in a lot of these cases,” says Bamberger. “It gets very frustrating when you start saying: What was in the tissue? What killed these animals exactly?”
In 2010, the Pennsylvania Department of Agriculture quarantined 28 head of cattle after they drank wastewater from a fracking site in Tioga County. The fear was that a radioactive contaminant in the water, strontium, would end up in beef.
In December 2011, the Environmental Protection Agency linked water pollution to fracking for the first time, after examining contaminated water in central Wyoming.
Note to New York
Last month the federal agency announced it would test water in dozens of homes around Dimock, Pennsylvania, a hotbed of fracking activity. It also told New York it would need to improve safeguards for drinking water before tapping into the Marcellus Shale.
New York placed a moratorium on fracking in 2010 so it could revise the rules governing the practice. Bamberger and Oswald are among those who contributed to the tens of thousands of public comments on the draft regulations, which were closed last month.
Bamberger submitted the published study; Oswald contributed 15 pages of his own to denounce the inadequacy of the proposed rules.
“There are so many flaws in the document,” he says. “It is unlikely to be able to protect us from the industrialization of our landscape and hydraulic fracturing.”
Now, New York’s Department of Environmental Conservation will review comments and revise regulations as necessary. It seems inevitable that the state will be fracking eventually, so the question is whether the industry can proceed safely — for humans and animals.
New Yorkers should listen to the stories of farmers, hunters and vets before making the same fracking mistakes that are being made elsewhere.

This is a new one from the hack scientists at Cornell. I’ve not heard this angle yet.
And I love the pic of the little kitty.
Dramatic.
Somebody has guaranteed Cornell U a huge donation to the endowment fund. Are there any honest research professors at the place ? If there are, they should royally embarrassed by now.
BTW, farmer says he smelled gas.
I always thought your local gas company who delivers the retail product, had to add mercatum ( sp ) to give it an odor, since nat gas is basically odorless ???
Fracaphobia is spreading like crazy.
This story has as much credibility as the alien stories in the National Enquirer. Look at the author and his so called field of expertise.
First of all, Dollar’s thought was my first thought. Methane from the ground has no smell. Next, I am here in AR, in the middle of the Fayetteville Shale. Right now there is a rig I can see less than a mile from where I sit. We have 20 wells, (+/-), within a mile of here. We have three cats and a dog on our place, all of which are healthy as can be. We are surrounded by cattle operations, none of which have given up on cattle due to wells being fracked. I hate when these sensational stories come out describing how terrible it is to live in the production area, because I live in the production area and I know better. Enough of the Chicken Little stuff, work on solving real problems.
Hydrogen sulfide is often found in gas wells. It does smell fairly foul, and it’s quite lethal in low concentrations. If it’s leaking from the ground, there are two reasons: the well has a faulty casing, or there are natural seepages from shallow formations.
Does the fracturing cause this? Waste water, drilling fluids, and other surface materials are plenty toxic. I wouldn’t drink it. The stuff you clean your house with is nasty, I know I wouldn’t drink that either. Theres probably plenty of nasty things you’re exposed to on a regular basis, but nobody knows what health ramifications they have. The link between fracturing fluid and the death of flora and fauna is tenuous at best.
That’s the link that this article fails to make. Plenty of geologists, geophysicists, and engineers can’t come up with a consensus, so I don’t think this author really has the backing to make the claims that he puts forth.
This kind of reporting is exactly why rational discussions cannot take place.
How about soil testing in the areas in question ?
One could analyze for HS HF, Mercury ( HG ), and lead, and see what the results are. Then, this can be compared to the fracing compounds.
We are all going to die of something. That is a fact. With all the negative news out there, we probably stand a better chance of dying of a heart attack from the stress of believing every news story that comes along. The oil and gas services industry provides a much needed product and provides LOTS of jobs. We take for granted the gasoline we put in our cars and the natural gas that we cook with and heat our homes with.
We don’t appreciate the things we have.

I’m 56 years old female, living on 40 acres here in Gene Autry, OK, and right across the street and all over the county, wells are being fracked at an alarming rate. I’m now having seizures, tics, tremors and a speech impediment. My pond is covered with oily residue and my husband and I both have bleeding ulcers, and all this happened in the past year since 4 wells have been fracked right across the street from me. One of my cats is having seizures and none of my goats kidded this year. So what about my story? do you want to discredit me as well? Go ahead and deny the evidence, it doesn’t make those of us who are dying from these toxins any more healthy. And for those of you who haven’t had any problems, well good for you. I’m well pleased. But not everyone has been so lucky. Sincerely Kathy M. Dixon
