CELL 2E-2 KING AND QUEEN LANDFILL
KING AND QUEEN COUNTY, VIRGINIA
------------------------------------------------------------------------------------------------------
The Cell 2E-2 construction project at King and Queen Landfill consisted of a 4 acre "piggyback" municipal waste landfill cell adjacent to three (3) active landfill cells on the east, south, and west sides of the proposed new cell. Construction consisted of, in ascending order, placement of a 24" low permeability clay liner, installation of a double High Density Polyethylene (HDPE) geomembrane liner system, and the placement of an 18" layer of leachate collection aggregate with associated leachate collection piping. Complexities of this project not only involved the integrating of the new cell layers with the existing cells' layers on three adjacent sides, but also included the connection to an existing leachate collection manhole situated within the waste of the lower eastern adjacent cell.

Duffield Associates was on site to perform Construction Quality Assurance Inspection (CQA) of all phases of construction along with soils and geosynthetics quality assurance testing both onsite and at the in house soils/geosynthetics laboratory. Upon the conclusion of construction of Cell 6, Duffield Associates compiled and wrote an as-built construction certification report for review by the Virginia Department of Environmental Quality (VDEQ), to certify that construction was performed according to site design specifications and VDEQ regulations.
