An independent assessment commissioned by the Chesapeake Climate Action Network and Citizen Shale, two Maryland environmental groups, warns hydraulic fracturing (fracking) in the state would pose a “high risk” to Maryland air and water.
The assessment, titled, “Shale Gas Risk Assessment for Maryland,” was conducted by Ricardo-AEA, the same United Kingdom-based independent environmental consulting firm that led the European Commission’s hydraulic fracturing risk assessment and regulatory review.
To develop an evaluation of the potential impacts of fracking in Maryland, the firm reviewed evidence of environmental and health issues associated with hydraulic fracturing, the gas industry’s standard operating practices and Maryland’s current regulatory framework. In the process, Ricardo-AEA conducted a literature review of more than 200 documents and evaluated Maryland-specific geological data. The study did not address climate or carbon footprint issues.
The assessment found a cumulative risk grade of “high” or “very high” in nine of ten qualities if fracking were to occur in Maryland. The qualities included a high risk of surface water contamination, ground water contamination, noise impacts, visual impacts, increased traffic and threats to biodiversity.
Additionally, the study notes fracking is estimated to use 3.88 million gallons of water per well, threatening Maryland water supplies from two sides. Fracking would also produce dangerous air emissions such as particulate matter, nitrogen oxides, carbon monoxide, volatile organic compounds and sulfur dioxide.
The study also predicts a “very high risk” of undeveloped land being taken over for development, with up to 10 percent more land needed for full development of a gas reservoir than is currently described as developed in Maryland's Allegheny and Garrett counties.
Though two western Maryland counties, Allegheny and Garrett, lie above the Marcellus Shale, fracking is currently prohibited in the state.
