Medical And Scientific Experts Urge Halting Fracking Rush Until Medical Unknowns Are Better Understood

This week, the group Physicians, Scientists, and Engineers for Healthy Energy (PSE) declared they would submit a petition to the White House signed by 107 experts to urge the administration to slow down and consider the health effects of natural gas fracking before allowing any new permits. They want the government to consider the two ethical principles adhered to by physicians: “do no harm” and that of “informed consent.”

The petition stems from the possibility that the Obama administration might “fast-track” the permits for LNG exports. LNG, or liquefied natural gas, comes almost exclusively from the fracking process. The government wants to build export terminals to sell the gas overseas, which would increase demand and production for fracked gas within our borders.

The main concern is with flowback water produced during the fracking process that comes back up to the surface. Companies still won't reveal what's in the chemical fluid mixed with water used to extract the gas citing a potential “loss of competitive advantage.”

Even with known chemicals, doctors and scientists are still studying the ways that public health could be put at risk by exposure. The flowback water from the wells poses a high risk to communities through both water and air contamination.

Alberta Bitumen Threatens Health of Communities Living Near Refineries in U.S., ForestEthics Reports

Toxins from refineries processing tar sands bitumen are dangerously polluting the air of local communities in the United States, according to a recent report by ForestEthics. Areas surrounding tar sands refineries - where a higher proportion of society's vulnerable minority, aging and poor communities live - exhibit intense levels of sulfur dioxide (SO2) as a result of the high sulfur content of bitumen feed stocks used in the process. Sulfur dioxide pollution is associated with asthma and heart disease.

“The growing use of Canada's tar sands by U.S. refineries adds another health risk to those already being faced by some of the most disadvantaged communities in the United States,” said Aaron Sanger, U.S. Campaigns Director at ForestEthics and author of the report, in a press release.
 
At current rates, the U.S. imports 99 percent of Canadian bitumen exports. That oil is refined near low-income areas, meaning the health effects fall disproportionately on communities with disadvantaged groups. African American and Latino populations suffer higher cancer risks from refinery pollutants than the general population, according to the EPA.
 
The ForestEthics report, Tar Sands Refineries: Communities at Risk, shows that refineries upping their intake of tar sands bitumen have a correlative increase in SO2 emissions.
