SP2. Impact of surface activities: Water, soil and well site activities
The target of this subprogramis to determine possible impacts of activities conducted during exploration and exploitation extraction of shale gas on quality of
water, soil and broadly defined infrastructure in Europe. Surface activities connected with the exploration and extraction of gas from shale formations in Europe
is a source of controversy. One of the most discussed problems in this context is the potential impact of these activities on the natural environment. To date,
the exploitation of shale gas resources requires the application and injection of water with additives for the hydraulic fracturing process and for enhancing the
gas extraction from the shale. The amount of water used, the additives and flow back, and waste water may constitute a significant risk of negative impacts on environment. The composition and proper management of different types of waste generated by shale gas operations are studied as well as the composition
and sustainable management of waste water. Environmental compatibility and social acceptance, synchronized with economic efficiency and security of supply,
are the four fundamental corner stones that have to be fulfilled if shale gas is to be sustainably exploited in Europe. Research activities will provide an inventory
of potential surface hazards and develop monitoring methods. Good practices will be worked out which will make it possible to reduce any negative impact of
works connected with exploration and extraction of gas from shale formations on environment, including impact of well site infrastructure and transport.
Moreover, the development of appropriate risk assessment strategies for the individual elements of the natural environment need to be formulated. The research will be used together with reviews of existing data to provide integrated scientific recommendations for best practices on minimising the footprint on the surface
that will be input to the integrated European knowledge base including all risks, impacts and scientific recommendations.
