ANR - Environmental baseline conditions for impact assessment of unconventional gas exploitation: advancing geochemical tracer and monitoring techniques

点击翻译按钮获取中文摘要

The recent expansion of the unconventional gas industry in North America and its potential advent in Europe has generated public concern regarding the protection of groundwater and surface water resources from contamination by stray gas, saline formation water and fracturing chemicals. A major scientific challenge and an indispensible prerequisite for environmental impact assessment in the context of unconventional gas development is the determination of the non-impacted baseline conditions against which potential environmental impacts on shallow water resources can be accurately and quantitatively tested. The objective of this Franco-Canadian NSERC-ANR project is to develop an innovative and comprehensive methodology of geochemical and isotopic characterization of the environmental baseline for water and gas samples from all
