Using data from natural gas distribution utilities on expenditures and volume of methane leaked, this paper estimates the amount of money utilities are spending to abate leaks. Expenditures are suboptimal at less than the cost of gas itself.
Using property value data from New York and Pennsylvania to look at the impacts of proximity to a shale gas well on home values, experts find that the effects differ depending on whether homes have access to piped water versus well groundwater. (Published in the American Economic Review)
This study, published in the Proceedings of the National Academy of Sciences, shows that shale gas development can adversely affect surface water quality by increasing the downstream concentrations of two pollutants, chloride and total suspended solids.
In this study of Washington County, Pennsylvania, experts find that proximity to wells increases property values, but groundwater contamination concerns fully offset those gains by reducing property values.
