A project examining the local health impacts from natural gas drilling is providing some of the first preliminary numbers about people who may be affected, and the results challenge the industry position that no one suffers but also suggest the problems may not be as widespread as some critics claim.
The Southwest Pennsylvania Environmental Health Project (EHP) has been trying to help people who feel they’ve been sickened by natural gas drilling or processing for about 18 months in one county south of Pittsburgh.
The work is potentially important because it’s one of the first long-term attempts to monitor drilling-related health impacts, and it could help other groups identify possible symptoms.
The project found 27 cases where people in Washington County believe they were hurt by nearby drilling — seven cases of skin rashes, four of eye irritation, 13 of breathing problems and three of headaches and dizziness. The skin exposures were from water and the other cases were from air. The numbers don’t represent a full survey of the area, just cases so far with plausible exposures.
The EHP group is trying to help those who have been exposed to drilling-related air or water pollution, toxicologist David Brown told The Associated Press, adding that they’re finding “an array of symptoms” in some people who live close to either wells or processing stations.
There are some surprises: Air pollution seems to be more of a threat than water pollution, and the huge processing stations that push gas into national pipelines may be more of a problem than the drilling sites themselves. The processing stations can handle large volumes of gas from hundreds of wells.
Washington County has a population of about 200,000, and about 700 natural gas wells have been drilled there in the past six years. It’s also home to large gas processing operations.
Some experts not involved with the findings praised the general program but said the debate over fracking and health often neglects a crucial point.
Brown said one of the most worrying findings was the extremely high levels of air pollution found inside two homes that are about 1,000 feet from a gas processing station. Western Pennsylvania tends to have high levels of air pollution, but the levels found in the two homes were up to four times higher than the local average.
Brown said the group is collecting more data and pushing ahead to refine ways to advise people who are worried about nearby natural gas activity.
