Ordot Landfill Closure

Situated on 63-acres of land, the Ordot Dump had been the sole disposal facility for Guam’s waste since the 1940s. Undocumented materials including unexploded ordnance and leachate discharge had hampered closure efforts for years. Brown and Caldwell led the investigation and design team that developed the closure plan and ended an era of long-running environmental issues, including releases of contaminated leachate into local water bodies, methane gas emissions, and odor problems. The plan includes a path to achieving Subtitle D and Clean Water Act compliance, converting a portion of the site to a public park, and using landfill gas to generate up to 500 KW of power. Brown and Caldwell is continuing post-closure activities by performing inspections, O&M, and implementation of the site post closure monitoring plan.
