- Secure landfills require all but ONE of the following? a. Single liners b. Ground water monitoring C. Financial guarantees for post closure activities d. A Leachate collection systemList the 5 critical elements of a municipal landfill based on many current State requirements.How important is the implementation ofaSanitary Landfill in the economy ofacountry? And how vital is the involvement of the society in its operation?
- List four differences between sanitary (municipal) landfills and secured (hazardous waste) landfills.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.
- State FOUR (4) factors to be considered in landfill designWhat is sanitary landfill and describe its methods?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
