Chevron currently extracts shale gas in several regions (China, USA, Canada, Argentina, and Eastern Europe) using the controversial method of hydraulic fracturing (“fracking”).
The fracking process taps natural gas and other underground resources that would be otherwise unreachable by traditional means of extraction. The process involves shooting highly pressurized water, silica sand, and some 596 chemicals (arsenic, radioactive material, etc.) into the ground creating horizontal fractures in the earth´s crust that release and channel resources into horizontal wells and storage tanks. Leaks are frequent and research shows that shale gas´s “climate advantage” over coal will eventually disappear. Hydraulic fracking raises several environmental concerns, in particular, the possibility that chemicals and released substances from the fracking process could contaminate groundwater. Water used for hydraulic fracturing endangers employees, the public, and the environment if not properly decontaminated and disposed of. Many claim that groundwater contamination is already occurring in regions that permit fracking. Health conditions stemming from this type of water contamination range from mild dizziness, headaches, and asthma to cancer and permanent brain damage.
According to Lech Kowalski´s documentary, Drill Baby Drill, companies frequently dump contaminated wastewater from hydraulic fracking into community fields and streams as an alternative to paying for wastewater treatment. Employees who do not comply with the practice risk losing their jobs.
Chevron began extracting shale gas in Poland in 2012. Residents in the community of Żurawlów protested against drilling in their district. The company failed to adequately inform landowners of the consequences of extraction. Chevron´s seismic research in the area caused houses to crack; the repetitive explosions also contaminated local water. In Otyn, Poland, drilling activities caused a local church to collapse. Several communities have complained to the European Commission claiming that the company´s Polish operations are not in accordance with EU standards regarding environmental destruction and public participation. However, the EC pointed to the responsibility of the Memeber States in such matters. 
Opposition is also building to Chevron’s shale gas ambitions in Argentina where local communities, the Mapuche, claim Chevrons deal is illegal as they, the local community, were not consulted. Protests have already taken place in opposition.
