Shale gas development has the potential to transform the Canadian economy creating jobs, significant wealth and energy security over the coming decades. However the necessary extraction technique, i.e. hydraulic fracturing, could potentially give rise to significant environmental impacts. Contamination of shallow groundwater by leakage of natural gas originating from shale gas development is one aspect of significant concern about which little is known. In particular, knowledge on the most effective monitoring and detection methodologies regarding natural gas contamination in groundwater and the potential impacts on groundwater quality over appropriate temporal and spatial scales is lacking. Thus prior to widespread shale gas development within Canada it is essential that the implications of groundwater contamination by natural gas and the most effective monitoring and detection strategies are investigated, proven and employed. This strategic project aims to address uncertainty regarding natural gas contamination by undertaking a controlled natural gas release experiment. During the experiment natural gas will be released in a controlled manner into shallow groundwater and the effects monitored in space and time. Following release, the recovery potential of the groundwater to natural conditions will be evaluated. The proposed experiment aims to (1) determine the effects of natural gas on groundwater quality; (2) determine the most effective ways to detect natural gas contamination; and (3) aid in the design and development of monitoring and detection strategies. The overall objective is to make shale gas extraction a more environmentally friendly and sustainable technology.

页岩气发展有可能改变加拿大经济，在未来几十年中创造就业机会，大量的财富和能源安全。但是，必要的提取技术，即液压压裂，可能会产生重大的环境影响。通过泄漏源自页岩气体的天然气对浅地下水的污染是对哪种知之甚少的一个方面的一个方面。特别是，缺乏有关地下水中天然气污染的最有效监测和检测方法的知识以及对适当的时间和空间尺度的地下水质量的潜在影响。因此，在加拿大境内广泛的页岩天然气开发之前，必须研究，证明和使用天然气污染地下水污染以及最有效的监测和检测策略。该战略项目旨在通过进行管制的天然气释放实验来解决有关天然气污染的不确定性。在实验期间，天然气将以受控的方式释放到浅地下水中，并在时空中监测的效果。释放后，将评估地下水对自然条件的回收潜力。提出的实验旨在（1）确定天然气对地下水质量的影响； （2）确定检测天然气污染的最有效方法； （3）帮助监测和检测策略的设计和开发。总体目标是使页岩气提取成为更环保和可持续的技术。
