Published in the Proceedings of the National Academy of Sciences on Monday, the research showed three homes in Bradford County with water wells containing multiple compounds similar to the mix used by drilling companies. The amount of those compounds were small, however, and did not pose a health risk, the authors said. One of the households’ water supply contained 2-Butoxyethanol (2BE), a commonly used drilling chemical that is known to cause adrenal tumors in animals (it’s unknown if it causes cancer in humans). In that case, the water well was “foaming,” the study says.

[Even though it does not pose a health risk, what will happen if we drink that water for 10, 20 years? Science never talks that. Science is politics.]
