Investigating the traffic-related environmental impacts of hydraulic-fracturing (fracking) operations (13 page pdf, Paul S. Goodman, Fabio Galatioto, Neil Thorpe, Anil K. Namdeo, Richard J. Davies, Roger N. Bird, Environment International, Feb. 1, 2016)
Today we review an aspect of fracking, not often investigated: the impact of local fracking wells which is a combination of the air pollution emissions from the fracking itself and the removal of waste water by tanker trucks which adds vehicle emissions and noise. There is a requirement for 9,000 to 29,000 cubic metres per well, or 54,000 to 174,000 cubic metres for a six-well pad. Total CO2 emissions associated with extraction of shale gas from a well were small (0.2–2.9%) compared to the combustion of the gas from the well. Modelling of NOx emissions showed increases reaching 30% over non-fracking periods and noise levels doubling.
