Editor's Notes
Largest part of the Marcellus Shale gas is found under Pennsylvania, across 64 percent of the state.
As part of the hydraulic fracturing process, drilling companies combine a cocktail of chemicals with sand and millions of gallons of water, forcing the fluid underground at high pressures in order to help break up the shale and access the natural gas. In total, 85 chemicals have been posted on PA DEP’s website as chemicals that could be used for hydraulic fracturing in the Marcellus Shale. Many of these chemicals, including toluene, xylene, trimethylbenzene, and petroleum distillates which often contain benzene are known or suspected carcinogens, or have other negative health effects. Chemicals are used in many phases of extracting gas from shale: added to the “muds” used to drill the bore hole. Chemicals added to increase weight of fluids, reduce friction, shorten drilling time.
Drilling can affect drinking water in a variety of waysA large volume of toxic wastewater is generated during the hydraulic fracturing processUnfortunately, most sewage treatment facilities in PA do not have the technology or capacity to deal with this type of industrial pollution, though many have been permitted to accept this water.In 2008, state environmental officials issued a drinking water advisory for 325,000 local residents after reporting that inadequately treated drilling wastewater was discharged into the Monongahela River, which serves as the drinking water sources for downstream communities.In Susquehanna County, Cabot Oil & Gas reported that private water sources has been contaminated with methane after Cabot’s natural gas drilling activities broke through nearby residents’ underground well water supply.In the photo above, you can see multiple Marcellus wells that have already been drilled near the Beaver Run Reservoir, which is owned by the Westmoreland Water Authority and is a source of drinking water for thousands of residents northeast of Pittsburgh.
With the growing pressure to promote natural gas exploration across the Commonwealth, state officials last year opened up 74,000 additional acres of state forestlands to bids from natural gas companies in spite of broad and deep public opposition to the proposal. Sadly, state regulators have already signed off on allowing companies to drill for natural gas on 660,000 acres of Pennsylvania’s state forestlands—a full 40 percent of the Commonwealth’s entire state forest system that sits on top of the Marcellus Shale formation.There’s now a ban in place on any additional leasing of state forestland for gas drilling, but this could be overturned by the current administration.Also, there has been exploratory drilling that has occurred in Ohiopyle State Park, which could mean that our state parks could be next.
When gas is being compressed, or when it is stored in a condensate tank, the harmful but invisible air emissions can leak into the atmosphere. This, combined with the diesel-powered drilling rigs, and roughly 1,500 diesel trucks necessary for every well hydraulically fractured, results in localized air pollution and oftentimes ground-level ozone. A recent study by Dr. Theo Colburn and the Endocrine Disruptor Exchange found that air is the primary pathway of concern for fracturing chemicals.
Each natural gas well requires roughly 2 to 6 million gallons of water for the hydraulic fracturing process. Natural gas companies often take this water from nearby rivers and streams, damaging local ecosystems. In some cases, especially in Western Pennsylvania, these withdraws have occurred without proper oversight or approval. Already, Pennsylvania’s Department of Environmental Protection (DEP) has fined companies for illegal water withdrawals. In the worst cases, so much water is removed that streams have completely dried up and disappeared. Sugarcamp Run in Washington County is one example of a waterway that ran dry in 2008 due to excessive water withdrawals from natural gas drilling companies. This type of stress is inevitably causes far-reaching damage to aquatic species in these streams. Especially of concern during summers like this past, where drought warnings were issued for 24 counties in PA
