Sounds of rushing water have been reported behind the walls of the lower concourses of the World Trade Center site. As DNAinfo reports, rumors say officials have found an underground leak within the newly built complex and fear that it may be coming from the 3,200-foot-long slurry wall that separates the site from the Hudson River.
The four-foot-thick, 100-foot-deep wall was originally declared an engineering feat when built in the 1960s. Although damaged, it held up during the 9/11 attacks, yet had to undergo significant (and expensive) renovations.
Some think the wall may have not been properly insulated, allowing water to pass. However, the Port Authority has declined knowing of any issues regarding the wall.
