Former ADEQ Director and former EPA official Ben Grumbles [right, credit Rose Law Group] did an extensive interview with ProPublica on the topic of hydrofacturing ("frac'ing") of oil and gas wells.
The interview headline and news reports are focusing on his statements about Congress making the 2005 exemption from the Safe Drinking Water too broad, but there are a lot of other complex and nuanced remarks that make it sound not so black and white.
Ben left ADEQ last October to take a position with the Clean Water America Alliance in DC.
