A new peer-reviewed study from Duke University shows that drinking water in areas within a half-mile of fracking wells can become contaminated with dangerous levels of methane - enough to catch on fire if lit. The report says that the levels of methane in some areas of Pennsylvania and New York are so great that they pose a significant fire and explosion hazard.
The study was published this week in the Proceedings of the National Academy of Sciences. One of the study’s authors, Duke environmental science professor Robert Jackson, says that the threat of explosions in this drinking water are real and need to be dealt with. From a CNN report:
“The study said about half of the 68 drinking water wells tested in Pennsylvania and New York located within a half a mile from natural gas wells had high levels of methane – the prime ingredient in natural gas fuel…The gas, which is usually located thousands of feet below the water table, appears to be entering the water wells either through cracks in the bedrock or, more likely, the casing in natural gas wells… Casings are steel and concrete barriers natural gas companies use to line a well where it passes through the water table.”
