Study: Living Near Fracking Correlates With Increased Hospital Visits
New submitter Michael Tiemann writes: An article published in PLOS One finds increased hospital admissions significantly correlate with living in the same zip code as active fracking sites. The data comes from three counties in Pennsylvania, whose zip codes mostly had no fracking sites in 2007 and transitioned to a majority of zip codes with at least one fracking site. While the statistical and medical data are compelling, and speak to a significant correlation, the graphical and informational figures flunk every Tufte test, which is unfortunate. Nevertheless, with open data and Creative Commons licensing, the paper could be rewritten to provide a more compelling explanation about the dangers of fracking to people who live within its vicinity, and perhaps motivate more stringent regulations to protect them from both immediate and long-term harm.
Since there are a lot of things that correlate with location of fracking sites, such as lower income, better chance of hurting oneself on drilling equipment, rural areas, it would lend more credence to the study to list if there were also more hospitalizations in those zip codes compared to other zip codes BEFORE fracking started.
If you are not allowed to question your government then the government has answered your question.
It means that these people are trying to RAM smoke up your arse, but cannot make it look convincing enough even then,
so want help to polish the turd.
They are trying hard to pull a 'correlation is causation' scam, but dont even have the ability to do that it seems.
Perhaps they need to ban Icecream first.

The obvious problem here is that there is almost certainly a correlation between these locations and poorer communities,
which also have a very well established correlation with increased health issues.
The scary thing is that this is even being reported. Congratulations Slashdot. It almost but not quite makes it to satire!
Also, receiving a monthly royalty check from the gas company increases your disposable income, and means you can spend more on things like health care.
Note that during that study period sales at McDonalds across the nation were dropping. We thus can conclude that reduced sales at McDonalds leads to higher number of hospital visits.
I bet living near hospitals correlates to more hospital visits too.
Don't waste your vote! Vote for whoever you want, unless you live in a swing state it won't matter anyways
one causation is working on a fracking rig. its probably dangerous, and there are probably a lot of new people in the area who were not prior. making hospital visits go up when populations, especially those in dangerous jobs go up
have you seen my sig? there are many others like it but none that are the same
The two "significant" effects, for cardiology and neurology, are increases of 0.07% and 0.06%, respectively. Not 7% and 6%, but 0.07% and 0.06%. These are the smallest effect sizes you will ever see published. Effect sizes of that tiny size can easily be explained by decisions on which data to use, how to analyze it, etc. Even if those effects were real, those effect sizes are too small to care about. Nothing to see here. Move along.
"...the graphical and informational figures flunk every Tufte test, which is unfortunate" -- Says so much about the author of the post. .06% increase in a data set of this size is compelling? It stinks when the data doesn't fit one's preconceived notions.That's one of the the beauties of science and why healthy scepticism is required.

Or, the economy in the area improves and now more people can afford to get their health problems looked at. Unless specific billing codes are increasing, this is the second most likely explanation. The most likely explanation is that they did a bunch of tests and didn't correct for multiple testing in their stats.
Exactly. The oil was found and drilling started in 1895 before their were rich people there. But no fracking on the Beverly Hills Oil Field in 2015, even though 2/3 of the oil underneath will require it.
And that's because the people who live there have the means to prevent it. You will also note that the oil rigs are hidden behind soundproof walls.
You are welcome on my lawn.
Extraction sites tend to be located in under developed rural areas where income levels are lower than in highly populated urban centers. Although there are oil pumps scattered throughout some of the wealthy suburbs of LA that are hidden by clever landscaping. They could discover vast oil and gas fields under any large city but the costs to get at such a resource is astronomical. Energy resource extraction has always been dangerous, dirty, expensive, and controversial. But the fact is even those complaining the loudest against exploiting fossil fuels directly benefit from the oil,,gas, and petroleum products produced. The environment also takes a major hit when extracting the rare earth elements needed for building all of our modern day electronics. Everything from computers, cell phones, and cruise missiles. The toxicity emanating from these mining areas is almost as dangerous as a open nuclear waste landfill. The US closed down almost all of the rare earth element mines because the cost of satisfying the EPA requirements made it cheaper just to buy the rare earth elements mined in foreign countries.

Another very likely explanation is that the correlation is cherry-picked. A good way to achieve a study like this is to look for correlations across numerous statistics (e.g. health costs, mortality rate, days of work missed due to illness, etc., etc., it's easy to come up with a dozen proxies for "health"), and if you cast a net wide enough you're statistically guaranteed to find at least one with a correlation that exceeds the standard threshold for statistical significance. The definition of "statistical significance" ensures it. Then you publish that one while discarding the rest.
Moreover, you can achieve this same effect merely by having many research teams tackle aspects of the question. The negative results will go unpublished, or published in obscure journals and receive no mainstream press attention, while the one that "hits" shows up on slashdot, and not even the researchers will believe they've done anything wrong.
Or maybe the correlation is real, in which case we'll eventually find a cause. Time will tell, but it general goes against the sky-is-falling types.
