Shale Gas Production in England – an updated public health assessment

Medact released in July 2016 an updated assessment of the potential health impacts of shale fracking in England.  This new report reaches broadly the same conclusions as our 2015 report Health and Fracking, however it is now supported by a much larger body of evidence published in the year since the first report was produced.  In the …

Potential Contaminant Pathways from Hydraulically Fractured Shale to Aquifers

Potential Contaminant Pathways from Hydraulically Fractured Shale to Aquifers Author(s): Tom Myers Date: 05.2012 Journal: Groundwater Key findings: The reason fracking works to force gas out of the rock is also why some observers think injection wells could be unstable – the extreme pressure of injection can take nearly a year to dissipate. The lingering …
