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 three essential zones: (1) the production zone, including flowback waters, (2) the intermediate zone comprised of overlying formations, and (3) shallow aquifers and surface water systems where contamination may result from diverse natural or other human impacts. The outcome will be the establishment of a methodology based on innovative tracer and monitoring techniques for detecting and quantifying and modeling stray gas and leakage of saline formation water mixed onto flowback fluids into fresh groundwater resources and surface waters taking into account the mechanisms of fluid and gas migration. The new knowledge derived from this project will be of critical importance for ensuring the environmentally acceptable development of unconventional energy resources in Canada and Europe. Decision support and recommendations for stakeholders on meaningful baseline and monitoring programs in the context of unconventional energy ressources will be provided as final deliverable.

北美非常规天然气行业的最近扩张及其在欧洲的潜在出现引起了公众关注的关注，以保护地下水和地表水资源免受流浪气，盐水地层，盐水地层水和破裂化学品的污染。在非常规气体发展的背景下，对环境影响评估的主要科学挑战和必不可少的先决条件是确定非影响的基线条件，可以准确和定量测试对浅水资源的潜在环境影响。这个franco加拿大NSERC-ANR项目的目的是开发一种创新的，全面的方法论，是对所有人的水和天然气样品的环境基线的地球化学和同位素表征 三个必需区域：（1）生产区，包括流动水域，（2）中间区由上覆地层组成，以及（3）浅水含水层和地表供水系统，这些含有多样的自然或人类影响可能造成的污染。结果将是建立一种基于创新示踪剂和监测技术的方法，用于检测和量化和建模杂散气体以及盐水地层水的泄漏以及将流动性流体混合到新鲜的地下水资源中，并考虑到流体和气体迁移的机制。从该项目获得的新知识对于确保加拿大和欧洲的非常规能源资源的环境可接受的发展至关重要。决策支持和建议 在非常规能源的背景下，利益相关者对有意义的基准和监测计划将作为最终交付。
