, the controversial drilling method that is enabling a U.S. gas boom while bringing fears of groundwater contamination. The report called for better data collection of air and water data, as well as "rigorous" air pollution standards and mandatory disclosure of the chemicals used in the hydraulic fracturing process. Chu said that he would "be working closely with my colleagues in the Administration to review the recommendations and to chart a path for continued development of this vital energy resource in a safe manner".
Chu faced controversy for a statement he made prior to being appointed, claiming in a September 2008 interview with the Wall Street Journal that "somehow we have to figure out how to boost the price of gasoline to the levels in Europe." However, in March 2012 he retracted this comment, saying "since I walked in the door as secretary of Energy I've been doing everything in my powers to do what we can to … reduce those prices" and that he "no longer shares the view
