. Respiratory health : The report cites the dangers of methane emissions from natural gas drilling in Texas and Pennsylvania, which have been linked to asthma and other breathing issues. Another study found that 39 percent of residents in southern Pennsylvania who lived within one kilometer of a fracking site developed upper-respiratory problems compared with 18 percent of those who lived more than two kilometers away.
. Drinking water : Shallow methane-migration underground could seep into drinking water, one study found, contaminating wells. Another found brine from deep shale formations in groundwater aquifers. The report also refers to a study of fracking communities in the Appalachian Plateau where they found methane in 82 percent of drinking water samples, and that concentrations of the chemical were six times higher in homes close to natural gas wells. Ethane was 23 times higher in homes close to fracking sites as well.
. Seismic activity : The report cites studies from Ohio and Oklahoma that explain how fracking can trigger earthquakes. Another found that fracking near Preese Hall in the United Kingdom resulted in a 2.3 magnitude earthquake as well as 1.5 magnitude earthquake.
. Climate change : Excess #methane can be released into the atmosphere, which contributes to global warming. One study predicts that fracking in New York State would contribute between 7 percent and 28 percent of the volatile organic compound emissions, and between 6 percent and 18 percent of nitrogen oxide emissions in the region by 2020.
. Soil contamination : One analysis of a natural gas site found elevated levels of radioactive waste in the soil, potentially the result of surface spills.
. The community : The report refers to problems such as noise and odor pollution, citing a case in Pennsylvania where gas harvesting was linked to huge increases in automobile accidents and heavy truck crashes.
. Health complaints : Residents near active fracking sites reported having symptoms such as nausea, abdominal pain, nosebleeds, and headaches according to studies. A study in rural Colorado which examined 124,842 births between 1996 and 2009 found that those who lived closest to natural gas development sites had a 30 percent increase in congenital heart conditions. The group of births closest to development sites also had a 100-percent increased chance of developing neural tube defects.
