State Superfund Site-Remediation/Redevelopment
Corporate PRP; New York
Approximately 50,000 tons of non-hazardous waste was excavated and removed from this State Superfund site. Radioactive waste was segregated for separate disposal. C&D debris was recycled instead of constructing a more costly and restrictive landfill cap. The remediation made available an additional 12 acres for unrestricted commercial development, consistent with the Long Island Coastal Zone Management Plan.
Industrial Landfill Superfund Closure
Manufacturer; New York
Roux Associates closed a 25-acre State Superfund site in Syracuse, New York. Services included: remediation of adjacent wetlands; definition of landfill gas conditions; alternative cap design to reduce costs; construction management; and reporting. Roux devised alternate regulatory protocols and deliverables to greatly accelerate the design schedule to meet client objectives.
Industrial Landfill Closure
Chemical Company; Virginia
Roux Associates designed a cost effective alternative landfill cover and leachate treatment system for a multi-national chemical company. Key design elements included: Constructed Treatment Wetlands (CTW) for pH neutralization and metal removal from leachate and a Phytotechnology cap in place of the traditional RCRA cap to capture stormwater runoff.
BROS Superfund Site
PRP Group; New Jersey
Roux Associates implemented a $15 million RI/FS program at a landfill in New Jersey. As part of the final remedy, Roux designed a 20-acre alternative phytotechnology cover system, dramatically reducing leachate generation and saving millions of dollars over other possible remedies.
Alternative Landfill Cover
Manufacturing Facility; New York
Roux Associates designed a NYSDEC-approved alternative cover for a nine-acre industrial landfill which met landfill closure regulations (6 NYCCR Part 360) at greatly reduced cost. The cover vegetation includes native species to promote ecological diversity and create a valuable wildlife habitat currently used as part of the Corporate Lands for Learning TM program.
Landfill Leachate Treatment
Active Landfill; California
Roux Associates designed, permitted and installed 1,700 hybrid poplars at an active sanitary landfill to consume an estimated 30,000 gallons of leachate per day. The tree plot is a sustainable approach for leachate management that provides passive and low cost treatment and eliminates the need for an on-site treatment plant or trucking of leachate off-site.
