Waste management facilities are faced with a broad range of engineering, environmental and regulatory issues from historic waste management practices to present-day waste generation and disposal. Our experience includes municipal solid waste, industrial waste, hazardous chemical wastes, and radioactive materials at publicly owned landfills, industrial and commercial waste management facilities, and closed or abandoned sites. Our broad list of capabilities ranges from characterization and long-term monitoring for historic sites to new facility design and permitting to facility closure and post-closure care.
