The Marcellus Shale formation in Pennsylvania is one of America’s greatest natural gas resources. As one company scrambles to exploit this resource in Mount Pleasant Township, some residents are growing concerned about the potential for adverse health effects.

Range Resources Corp has drilled dozens of wells in the township to access water for a process known as “hydrofracking.” The process forces a chemical solution that includes benzene, methanol and over 200 others deep into the shale, and this facilitates the release of natural gas.

One research organization tested 54 chemicals in the fluid and found that:

• Nearly one-third are carcinogenic (that is, they are known to cause cancer)
• Nearly three-quarters cause respiratory problems
• Over half pose a risk to the blood and circulatory system

Indeed, benzene is known to cause a number of rare blood disorders and cancer, including aplastic anemia and acute myelogenous leukemia. And although a spokesman for Range Resources said the chemical solution is diluted and used at levels too deep for human exposure, citizens are still rightfully concerned.

The municipal supervisor for the township said he fears that the fluid will escape either above or below ground, and possibly contaminate groundwater. Another resident said she has stopped drinking from her wells and is having it tested because she’s concerned about its safety.

“I do feel the compulsion to make sure this [drilling] does not do horrible things to us,” she said.

Residents in this or other area of Pennsylvania where drilling is being undertaken may want to talk to their local representatives to learn more about measures being taken to prevent toxic contamination.
