Thank you for this letter. The secretive nature of fracking concoctions sets off and should set off alarms for anyone who values their water supply, their health, their children. What you don't know is more likely to hurt. It's a bit like labeling food. Would you eat some concoction with no idea what's in it? If the AOGCC is sure there isn't a danger, they should have no problem answering questions and making us aware of the details. The precautionary principal should rule. Just because the fracking corporations haven't researched or admitted if something is dangerous doesn't mean it isn't. The tobacco industry knew of the dangers of smoking for decades and denied what they knew. Why should we trust the corporations who stand to gain everything by keeping Alaskans in the dark?
