One of the greatest threats to animal and plant-life is the cumulative impact of rapid, widespread shale development, with each individual well contributing collectively to air, water, noise and light pollution
Determining the environmental impact of chemical contamination from spills, well-casing failure and other accidents associated with shale gas production must become a top priority.
The lack of accessible and reliable information on spills, wastewater disposal and fracturing fluids is greatly impeding improved understanding.
This study identifies that only five of 24 American states with active shale gas reservoirs maintain public records of spills and accidents.
... two out of three wells were fractured with at least one undisclosed chemical.
... fracturing fluid and wastewater, which can include carcinogens and radioactive substances, is often unknown.
...development that outpaces our understanding of ecological impacts can have dire unintended consequences,” notes Ryan. She is a research fellow in the University of Washington’s School of Environmental and Forest Sciences.
