Debate over a Weyerhaeuser landfill proposal in Washington state exemplifies the huge gap in landfill technology understanding between the industry and the public. One public opponent has contended he’s pushed a Bic pen through a landfill liner. Not only would one not be allowed to do this on a site, but it would not be possible given the heavy-duty geomembrane used in modern lining systems. Objection is fine; but accuracy and facts are better.
