A research team out of Yale School of Public Health found that residents who live closer to unconventional natural gas wells have more upper respiratory symptoms, such as cough, sore throat, sinus problems, and nose bleeds, than those who live farther away. In their study, "closer" means less than 1 km (0.6 miles) from a well, and "farther away" means more than 2 km (1.2 miles) from a well. Dr. Rabinowitz and his team also found that residents who live closer have more skin problems, such as rashes, burning, itching, and irritation, than those who love farther away. The researchers looked at a wide range of other symptoms, including gastrointestinal, cardiac, lower respiratory, and neurologic symptoms, but did not find that people who lived closer to gas wells were more likely to have these symptoms than those who lived farther away.
