Construction details on East Mound landfill capping

11.10.10

One of the most spectacular sights for visitors to the Freshkills Park site these days  is the installation of final cover on Landfill Section 6/7, the East Mound.  Final cover (also called the landfill cap) is composed of a series of layers of soil, synthetic textile, plastic and grass and is complemented by construction of adequate and sometimes elaborate drainage systems and basins.  The process of installing approximately 285 acres of final cover over the garbage at East Mound has been underway since 2006 and will continue through 2012.  Tully Construction, which has a long relationship performing work at the site—they also built the leachate control system and the Staten Island Transfer Station—runs a good summary of the work being performed on East Mound, with some staggering volumes and striking photos.
