On Wednesday, SkyTruth released a database created from over 27,000 “chemical disclosure reports” voluntarily submitted by industry to FracFocus.org for gas and oil wells fracked between January 2011 and August 2012. But as a few folks have pointed out, there are some obvious issues with this database: the data hardly represent all of the wells drilled; roughly 21% of the records are concealed as proprietary or “trade secret;” and the data include a wide variety of mistakes, from spelling errors to invalid Chemical Abstract Service (CAS) numbers.
So why did we publish this database?
