Contamination from former or current military installations has ignited a nationwide review of water on or around bases that used a firefighting foam containing toxic chemicals.
The military is now testing nearly 400 bases and has confirmed water contamination at or near more than three dozen, according to an analysis of data by the Philadelphia Inquirer and Daily News. The new numbers offer the best look to date at the potential scope of the problem.
But despite more than $150 million spent on the effort so far, the process has been slow and seemingly disjointed. The Air Force, for example, has completed sampling at nearly all of its targeted bases; the Navy, barely 10 percent. The Army has not begun. The branches and the Pentagon say they are coordinating, but have varying responses on how many bases must be tested, and limited information about remediation timelines and cost.
