Premature Announcement?

The EPA has begin investigating the fracking situation in Pennsylvania.  They began with the town of Dimock, which has been attracting attention re fracking since 2009.  The EPA planned to study the water situation in 60 homes.  After receiving lab results for 11 of these homes, the EPA decided to announce these results, which did not present a health concern.  Why they made this announcement with less than 80% of the results still to be analyzed is an interesting question.

The EPA has provided more information to many of the home owners.  It appears that there are a number of nasty things in the water of Dimock, but these nasty things have not yet been definitively explained.
