Not so good news In the Washington Post yesterday - is this turning into a Silver Springs?
In management alerts issued Friday, Metro Inspector General Geoffrey A. Cherrington said a sealant being applied to prevent water from seeping into hundreds of defective concrete panels may not be working. A sampling of sealant already in place found it was not working in all cases, leaving some panels vulnerable to cracking. Unless the panels are replaced or the contractor comes up with another solution, Metro should not accept the work, he advised.
