Fracking. How many must die before people wake up?

Note the closing paragraph…
There have been several other incidents at fracking sites in Ohio this year, according to the Dispatch. A well in Jefferson County ruptured in October, releasing natural gas and methane into the air and forcing the evacuation of nearby homes. In June, a fire at a Monroe County well pad caused a spill that stretched 5 miles along a creek and killed more than 70,000 fish, birds and animals.

Decades ago, when I was a graduate student, my advisor often said that our job as scientists was to put numbers on the obvious. Maybe it should be obvious that oil and gas production, including as it does the extraction, transport and processing of enormous quantities of hydrocarbon mixtures, will result in air pollution. However, studies that put numbers on this pollution have been rare.

The complexities of topography, weather and the variability in the production processes themselves make such studies difficult. Recently, Environmental Healthpublished a new study that “puts numbers” on air pollution near oil and gas infrastructure in five U.S. states and finds sobering results.

The study is a collaboration between 15 local, state and national nonprofit organizations. Our groups came together because we all share concerns about the potential but little studied health threats from the expansion of oil and gas operations, and in particular from hydraulic fracturing (fracking).

Our study is an example of community-based participatory research: the health concerns experienced by the local partners in the study were the impetus for the research. The local partners were trained to collect air samples and used their knowledge of local conditions to determine where and when to take the air samples.

About 40% of the samples we took contained at least one chemical at concentrations that exceeded risk levels established by either of two U.S. agencies, the U.S. Environmental Protection Agency and the Agency for Toxic Substances and Disease Registry. The chemicals that most frequently exceeded the risk levels were benzene and formaldehyde, both known carcinogens, and hydrogen sulfide, which can cause dizziness, sore throat, labored breathing and unconsciousness. Some of the pollution levels measured were extraordinary. For example, one site found benzene at levels that were 12,000 times the safety level established by government regulators.

Our results may surprise those who have heard claims that natural gas from fracking is a cleaner ‘bridge fuel’ to a climate friendly future. They suggest that oil and gas operations may not be as clean as advertised, and could pose unaddressed health risks to neighboring communities.

Given the gaps in air quality research around oil and gas operations, those of us who helped with the study hope that it will encourage more extensive future research, especially that which uses the expertise of local communities. We also hope that it will spur more robust air pollution monitoring by government agencies, more disclosure about the chemicals used in oil and gas production, a precautionary approach to new oil and gas development, and increased investments in energy efficiency and renewable energy.

In 2012, twelve community groups, with support from a team of national organizations, decided to test the air near oil and gas development sites located in their communities. A new report from Coming Clean and Global Community Monitor, titled “Warning Signs: Toxic Air Pollution Identified and Oil and Gas Sites” provides results from community air monitoring near oil and gas development sites including fracking sites in six states (Arkansas, Colorado, New York, Ohio, Pennsylvania, and Wyoming). For more information about the report visit

    Has it never occurred to The Frackers that mother nature has for billions of years intentionally kept all that gas and oil out of reach for the pure reason that it is not to be touched because of its detrimental effect on every ecological and environmental systems.

    On a daily basis we see the negative impact of mans’ interference with nature and its net effect, a wake of death and destruction, around our planet Earth, our home.

    Man has forgotten he is Earth’s steward and with stewardship comes great responsibility. Aeons past other civilisations have come and gone by nature retaliating with a strike of annihilation.

    Man must come to realise one way or another our home planet Earth is unique, it’s all we have and not to be destroyed but to be nurtured and improved upon as one would improve a home by decorating and furnishing it. If not, then we too must suffer the consequence of our actions as prehistoric and historic civilisations did to allow nature to heal herself and recover from the dis-ease of mankind.
