![]() Water qualityĬhemicals associated with natural gas and hydraulic fracturing may travel through cracks in the rock into an underground drinking water source. Mounting evidence related to environmental effects shows a need to analyze and quantify health and socioeconomic impacts using a common metric. More than two decades since the rapid expansion of unconventional natural gas extraction, researchers are now beginning to grasp the scope and extent of associated health effects and related costs. Research has provided some evidence about how unconventional natural gas development affects the health of those people in nearby communities. In some areas, such as Colorado, Oklahoma, Pennsylvania, and Texas, oil and natural gas extraction and development may occur close to residential communities. More than two decades since the rapid expansion of unconventional natural gas extraction, researchers are now uncovering the scope of associated health effects and related costs. Emissions of air pollutants are another potential hazard. Other concerns relate to chemicals that are recovered and disposed of as wastewater. Water quality is a primary concern because the hydraulic fracturing fluids used to fracture rock formations have chemicals that could harm human health and the environment, especially if they enter drinking water supplies. Residents, environmental advocates, and researchers are concerned about potential health effects and environmental impacts. Does hydraulic fracturing pose health risks to the people living near drilling sites? Hydraulic fracturing is part of a broader process known as unconventional natural gas development, which refers to all operations from well construction to the transport of gas and oil away from the drilling site. Using this method, drilling operators force water, sand, and a mix of chemicals into horizontally drilled wells, causing the shale to crack and release natural gas or oil. Hydraulic fracturing, or fracking, is a method used to extract natural gas and oil from deep rock formations known as shale. ![]()
