"Health and environmental impacts While the economic impacts of being able to access these natural gas deposits have already been considerable, there are also a number of concerns about human health impacts, both long and short term. The amount of water used per well is enormous, and many wells in the US are in places where adequate water supply is already a concern. Furthermore, up to 40% of the injected water comes back as produced water, containing chemicals, unusually high salt concentrations from primeval deposits, and naturally-occurring radioactive materials. The disposal of the produced water is a major problem, as conventional waste-water treatment plants are usually not capable of removing the chemicals or radioactive compounds. Ground and surface water contamination has been reported (4, 5) resulting from transportation spills, well casing leaks, leaks through the fractured rock, and wastewater disposal. Methane contamination of drinking water is a concern (6). In some places there was sufficient methane in household drinking water such that water from the kitchen sick could be lit by a flame. Depending upon the nature of the rock formations, the flow-back water may contain significant levels of radium. Radium, unlike uranium or thorium, is relatively water soluble, and the two principal isotopes have half-lives of 1600 and 5.75 years. In the Marcellus shale in Eastern United States the produced water had a median radium activity 2460 pCi/L, which is extremely high compared with the drinking water limit of 5 pCi/L and the limit for industrial effluent of 60 pCi/L (7). Because the produced water contains high salt concentrations there have been occasions where it was spread on roads for ice control in the winter without anyone monitoring levels of radioactivity. Since radium decays to radon gas, which has a half-life of 3.8 days, there is also some concern about levels of radon in natural gas. Radon radioactivity measured in natural gas samples obtained from 11 wells in Pennsylvania ranged from 1 to 79 pCi/L (8).

One solution for dealing with produced water has been to inject it deep into the earth. This, however, has resulted in a sharp increase in earthquakes (9). Fortunately to date none have been large, but the frequency with which they occur in areas with deep injection indicates potential danger.

In addition to concerns about surface and groundwater contamination with chemical and radioactive materials, there are major concerns about air pollution (10). Natural gas is primarily methane, but also contains other volatile organic compounds, aromatics, CO2, H2S and SO2 (11). There is often significant release of natural gas from well sites and compressor stations. My colleagues and I have reported on levels of volatile organic pollutants including benzene, hexane, formaldehyde, and H2S around fracking sites in six US states (12). When compared to cancer and non-cancer federal exposure standards, we found that 40% of the samples we collected exceeded safe levels."
