Geological Situation

Abstract Shale gas production in the US, predominantly from the Marcellus shale, has been accused of methane emissions and contaminating drinking water under the suspicion that this is caused by hydraulic fracturing in combination with leaking wells. Misunderstandings of the risks of shale gas production are widespread and are causing communication problems. This paper discusses recent preliminary results from the US Environmental Protection Agency (EPA) draft study, which is revealing fact-based issues: EPA did not find evidence that these mechanisms have led to widespread, systemic impacts on drinking water resources in the United States, which contrasts many broad-brushed statements in media and public. The complex geological situation and extraction history of oil, gas and water in the Marcellus area in Pennsylvania is a good case for learnings and demonstrating the need for proper analysis and taking the right actions to avoid problems. State-of-the-art technology and regulations of proper well integrity are available, and their application will provide a sound basis for shale gas extraction.

Discourse Historical Approach

This study explores strategies in pro and anti-shale organizations’ discourse by combining the Discourse-Historical Approach (Wodak, 2001) with corpus linguistics. With the help of keyword lists, collocations, concordances, and key semantic domains, the representations of shale gas extraction, relevant actors and argumentation schemes in opposing discourses of the pro-shale Marcellus Shale Coalition and anti-shale Americans Against Fracking were analyzed. The findings of the study show that the advocates presented shale gas as a bonus for the crisis-struck American society while backgrounding its environmental impacts. The opponents, on the other hand, represented shale gas as a threat to the American ecosystem and public health through an alarming and scientific discourse. The empirical findings of this study add to a growing body of literature on discursive strategies employed by opposing camps of environmental controversies.

Levels Of Support

This study compares public perceptions of shale gas extraction and hydraulic fracturing in two of the most populous states with significant shale gas reserves but with vastly different approaches to developing this resource. Drawing on data from a comparative survey administered to two statewide samples in Pennsylvania (n = 411) and New York (n = 404), the study examines the correlates of support for hydraulic fracturing, as well as general levels of public awareness, and perceptions of effects of hydraulic fracturing within the Marcellus shale play. Though the level of awareness of the fracking issue among residents of Pennsylvania and New York is found to be similarly high, levels of support for fracking differ, mirroring distinctive policy approaches found in these neighboring states. The correlates of support for fracking include being Republican, having a conservative ideology, and being male. The study also finds that residents of New York are more aware of fracking policy and debate in Pennsylvania than vice versa, with many New York residents perceiving negative effects on their home state as a result of fracking in neighboring Pennsylvania. This asymmetric level of awareness and concern raises new questions on the role of cross-­border perceptions in shaping opinion toward hydraulic fracturing in adjacent states.

Marcellus Formation

Extensive development of shale gas has generated some concerns about environmental impacts such as the migration of natural gas into water resources. We studied high gas concentrations in waters at a site near Marcellus Shale gas wells to determine the geological explanations and geochemical implications. The local geology may explain why methane has discharged for 7 years into groundwater, a stream, and the atmosphere. Gas may migrate easily near the gas wells in this location where the Marcellus Shale dips significantly, is shallow (∼1 km), and is more fractured. Methane and ethane concentrations in local water wells increased after gas development compared with predrilling concentrations reported in the region. Noble gas and isotopic evidence are consistent with the upward migration of gas from the Marcellus Formation in a free-gas phase. This upflow results in microbially mediated oxidation near the surface. Iron concentrations also increased following the increase of natural gas concentrations in domestic water wells. After several months, both iron and SO42− concentrations dropped. These observations are attributed to iron and SO42− reduction associated with newly elevated concentrations of methane. These temporal trends, as well as data from other areas with reported leaks, document a way to distinguish newly migrated methane from preexisting sources of gas. This study thus documents both geologically risky areas and geochemical signatures of iron and SO42− that could distinguish newly leaked methane from older methane sources in aquifers.
