Loony Labs: Shale oil has helped the US see lower gas prices and even an
opportunity to start exporting. However, it isn’t as great as it might

scrutinized by environmentalists since it’s inception. As it turns out,
for good reason, substances commonly used for drilling or extracting
Marcellus shale gas foamed from the drinking water taps of three
Pennsylvania homes near a reported well-pad leak, according to new
analysis from a team of scientists.
