Many people often generalize all oil industry issues as fracturing. Fracturing is a small part of the industry. Lots of problems can occur anytime with Drilling, cementing, and any stimulation (acidizing, etc). But if there is a problem it is always labelled as fracturing.

Contaminating water wells can happen, it is usually a cementing problem though. BP in the Gulf was a cementing issue. There was an EPA report, I'll see if I can find it, but the conclusion was fracturing contaminated water zones, but the last point of the conclusion was the cement bond logs showed no cement between the pay zone and the water zone, meaning behind the pipe they were attached so even without fracturing they were contaminated. better cement jobs and doing bond logs after to prove there is isolation between zones before and after fracturing treatments something that should be done.

I am a experienced stimulation chemist. I can answer some questions if you have any. But I'm a bad writer so don't pick on my spelling/grammar
