Potential Environmental Impacts of Shale Gas Development

Shale gas development has potential environmental impacts that need to be considered. These impacts can include groundwater contamination from chemicals used in hydraulic fracturing, air pollution from drilling activity and production, noise pollution from machinery and vehicles, and risks to flora and fauna from changes to the landscape. Groundwater Contamination: Shale gas development can potentially contaminate groundwater due to the chemicals and other substances used in hydraulic fracturing. This includes substances such as methanol, ethylene glycol, and hydrochloric acid which can seep into aquifer systems. Air Pollution: Drilling activity and the production of shale gas can emit pollutants, such as benzene and toluene, into the atmosphere. In addition, vehicular and machinery traffic to and from shale gas sites creates noise and air pollution, which can be a particular concern in densely populated areas. Noise Pollution: Shale gas development can cause noise, especially from the machines and vehicles necessary for drilling operations. This can have an impact on the quality of life in communities near the site. Risks to Flora and Fauna: Changes to the landscape, noise, and air pollution can have an impact on plant and animal habitats. These changes can cause destruction of ecosystems and reduce biodiversity.
