CLOSURE AND POST-CLOSURE Through our diverse and extensive engineering experience, WSP understands unique environmental and business challenges, which help us determine the right balance of social, economic and environmental solutions to help meet regulatory requirements for closing landfill facilities. Uncontrolled landfills can cause gas emissions, poor air quality, ground and surface water pollution and other environmental impacts. WSP can help waste management facilities develop practical, cost-effective solutions to optimize resources and meet regulatory requirements. Mitigating Risks Risk-based assessments help identify and quantify uncertainties that negatively impact the selected closure option. Developing a comprehensive risk management strategy that ranks and evaluates potential dangers is key in performance measures such as cost, schedule and available materials. Closure Design Identifying challenges that must be addressed for a properly engineered closure design helps us develop cost-effective options. With minimal long-term maintenance, we can design final cover systems for landfills that include gas control, leachate natural soil covers such as compacted clay and evapotranspiration covers and geosynthetic covers including exposed geomembrane, geosynthetic clay liner and geomembrane. Post-Closure Land Use Careful consideration must also be given to the intended end use and, by working together, we can find solutions for a variety of options. Successful post-closure conversion projects include converting land to open space, recreational facilities or sports complexes, commercial and industrial development sites and solar farms. management, and stormwater control. We have designed and provided CQA for
