Energy companies in Pennsylvania declined to identify potentially harmful chemicals used for drilling and fracking for natural gas in more than half the wells developed between 2013 and 2017, according to a report released on Tuesday.
The report from the Partnership for Policy Integrity, a Massachusetts nonprofit that does research and advocacy on energy policy, says companies withheld information about at least one chemical in 55 percent of wells drilled between 2013 and 2017.

Of the 62, manufacturers withheld the identities of 41 when reporting them to FracFocus, a national database of fracking chemicals, Horwitt said.
