Last week a train hauling frac sand for use in the Marcellus Shale derailed in Uniontown, Pa.
No one was injured, but several train cars landed near homes, spilling their loads of sand. The Federal Railroad Administration is investigating the incident.
The fracking boom has meant that frac sand has become an important commodity imported into Pennsylvania. The sand is used in hydraulic fracturing to help break natural gas free from shale rock. Only specific types of sand can be used, and much of it is being mined from Wisconsin and other upper Midwestern states. The type of sand spilled in the Uniontown derailment was Northern White sand from those areas.
According to Wisconsin Watch, a nonprofit news outlet similar to PublicSource, Wisconsin is the nation’s No. 1 producer of frac sand, with an estimated output of about 26 million tons annually, more than double what it was in 2012.
The increase of frac sand transported on railroads has caused some concerns in Wisconsin.
From Wisconsin Watch:
Wisconsin’s boom in the production of sand used for hydraulic fracturing has fueled a large increase in rail traffic moving the commodity to other states, causing conflicts and raising safety concerns.
While the number of Wisconsin car-train accidents has remained relatively steady in recent years, and derailments actually are down, some residents who live near train tracks used for transporting sand, primarily in western and northwestern communities, complain about noise and traffic delays in addition to safety worries.
Fracking has made the commodity a $10 billion industry, according to a recent MarketPlace article.
Frac sand be hazardous if inhaled over a long period of time, Bernard Goldstein, former dean of the University of Pittsburgh Graduate School of Public Health, told the Pittsburgh Post-Gazette.
“We worry about it mostly from a chronic exposure for workers,” he said.

This fact-based local reporting drives impact and creates change. Help power that impact.
James Baldwin wrote, “Not everything that is faced can be changed, but nothing can be changed until it is faced.” PublicSource exists to help the Pittsburgh region face its realities and create opportunities for change. When we shine a light on inequity in our region, like the “completely unacceptable” conditions in low-income housing in McKeesport, things change. When we ask questions about policymakers’ decisions, like how Allegheny County is handling COVID-19 safety for its employees, things change. When we push for transparency on issues that affect the public, like in the use of facial recognition software by Pittsburgh police, things change.
It takes a lot of time, skill and resources to produce journalism like this. Our stories are always made available for free so that they can benefit the most people, regardless of ability to pay. But as an independent, nonprofit newsroom, we count on donations from our readers to support this crucial work. Can you make a contribution of any amount (or better yet, set up a recurring monthly gift) to help ensure we can continue to report on what matters and tell stories for a better Pittsburgh?
