Forecast - Foggy with a chance of BS

In the Fort Worth Business Press, Alex Mills, President of a pro drilling group in Texas takes shots at New Jersey lawmakers for voting to protect their water supply from fracing.

He claims:  

How many times has there been a circumstance where groundwater has been contaminated by hydraulic fracturing? In 60 years and hundreds of thousand wells being fracked, not one case of pollution has occurred.

Back in the day, fracing was vertical, not horizontal.  And when he says not one case has occured, well, we're betting those families all over the country that can no longer use their water would have a different opinion.  Speaking of opinions, read the fine print under Mr. Mills column.  "The opinions expressed are soley of the author". 

What do they say about opinions, again??
