After seven years of operation and extensive vertical and lateral expansions, owners of the Kingsland Park Sanitary Landfill, located in northern New Jersey's Meadowlands, were ready to close the facility. State environmental regulations required that the closure cover have a clay component to limit water percolation and leachate generation. But engineers at Converse Consultants East, Parsippany, N.J., the owner's geotechnical consultant, feared the state-required cap would fail due to the ongoing settlements at the landfill. The cap, they claimed, would be a waste of money. Officials from the New jersey Department of Environmental Protection and Energy requested support for this argument. Converse engineers turned to data taken from piezometers and inclinometers, installed during the 1980s to ensure a stable site during expansion to prove their point--that a simple soil cover would get the job done for $20 million less than the required clay cap.
