- List the 5 critical elements of a municipal landfill based on many current State requirements.List four differences between sanitary (municipal) landfills and secured (hazardous waste) landfills.How important is the implementation ofaSanitary Landfill in the economy ofacountry? And how vital is the involvement of the society in its operation?
- Estimate the life of a landfill (years) given a population of 250,000 people, 40 acre, a maximum depth of 50 feet below ground, a pit slope of 1:3 and final slope of 1:4. The coversoil occupies 22% of the compacted volume. There is a 42% diversion rate, the waste is compacted to 1,270 lb/yd3, the population is stable and generates 6.2 lb/capita/day. The landfill area is square and the max height of the landfill is 33 yd.Which of the ff. is false regarding compaction in a solid waste landfill? a. It extends the life of the solid waste landfill. b. It discourages insects and rodents. C. It reduces the possibility of waste runoff/leachate. d. It reduces storm water runoff or infiltration.Estimate the life of a landfill for a user population of 10,000. The available area for the are-type landfill is 10 acres. The water table is estimated at 6.1 m (20 ft) below the ground surface. The pit must have side slope of 1:3, and the final surface must have a slope of 1:4. Assume that soil (used as daily cover) occupies 20% of the compacted volume of waste
