Methane Gasses
Methane Gasses
Landfills decompose and release methane requiring monitoring and venting. Improper operations can concentrate methane to dangerous levels
Current buildings foundations built with an impenetrable gas membrane layer
Vents and gas monitoring probes (the white poles stuck in the ground all over the site) installed
"Following Cell-Crete placement, elevated methane concentrations (40% to >100% of the lower explosive limit, or LEL) were detected within the utility trench at 3400 Bridge Parkway in December 2016 and continuing through January 2017." LINK (pg2)
Leachate Collection System
Leachate Collection System
An underground Leachate collection system was added to monitor, as well as remove liquids in the capped landfill
PVC pipe lines run along the South and East edges of the site property line
Pumps out to the local water treatment plant (sewer)
Currently outputs up to 3.5 gallons of leachate per minute
Pipe elevation relative to average tide is unknown
SLR and GWR may inundate it, rendering it useless or even worse, as a pathway introducing bay waters into the refuse
