The Impact of Marcellus Gas Drilling on Rural Drinking Water Supplies The Center for Rural Pennsylvania (2012) Report on water quality in private water wells in rural Pennsylvania before and after the drilling of nearby Marcellus Shale gas wells.
Role of Alternative Energy Sources: Natural Gas Technology Assessment National Energy Technology Laboratory (June 30, 2012).
Among the study's conclusions: Lifecycle greenhouse gas emissions from natural gas are lower than those from coal for electric-power generation and "control of fugitive (methan) emissions is imperative to reduce the greenhouse gas footprint of natural gas extraction, process and transport."
