Which term describes a facility designed to hold MSW with as little contamination of the surrounding environment as possible?

• A. Sanitary Landfills
• B. Siting
• C. Leachate
• D. Compost

Answer: (A)

Engineering a facility to hold municipal solid waste with minimal contamination relies on containment and controls that isolate the waste from the surrounding environment. That approach is embodied by a sanitary landfill, which uses protective liners to prevent groundwater intrusion, a leachate collection and treatment system to prevent contaminated liquid from spreading, daily soil covers to curb odors and pests, and systems to collect and sometimes utilize landfill gas. A final cap seals the site when it’s closed, helping to prevent future leaks. These features work together to keep groundwater, soil, and air as free from contaminants as possible while waste decomposes. Siting is about where to place a facility, not how it’s built. Leachate refers to the polluted liquid produced by waste, which must be managed within the facility. Compost is a method for treating organic waste to produce a soil amendment, not a containment site for municipal solid waste.
