TL;DR: Analysis of published data reveals evidence for stray gas contamination, surface water impacts in areas of intensive shale gas development, and the accumulation of radium isotopes in some disposal and spill sites.

TL;DR: In this paper, the authors evaluated the overall water footprint of hydraulic fracturing of unconventional shale gas and oil throughout the United States based on integrated data from multiple database sources, and they showed that between 2005 and 2014, conventional shale gas extraction used 708 billion liters and 232 billion litres of water, respectively.

TL;DR: Using temporal volume production and water quality data, a rapid increase of the salinity associated with a decrease of FP production rates during the first months of unconventional oil and gas production is shown.

TL;DR: The steady increase of the water footprint of hydraulic fracturing with time implies that future unconventional oil and gas operations will require larger volumes of water for hydraulic fracturing, which will result in larger producedOil and gas wastewater volumes.

TL;DR: In this paper, the authors analyzed the noble gas, dissolved ion, and hydrocarbon gas geochemistry of 72 drinking-water wells and one natural methane seep all located ≫ 1 km from shale gas drill sites in the northern Appalachian Basin (NAB).
