Landfills

The landfill is a site used for the disposal of waste materials. The landfill is a solid waste facility that is often known as a dumping ground. The image below shows a landfill site in Hawaii. Landfilling is the most ancient and common method used for the disposal of waste. For the landfill, a deep trench is constructed in an isolated place away from the city. The trench for landfills is designed properly after analyzing the total population and the waste generation per capita. The waste is dumped into the trench and after every layer of waste, a layer of soil is spread on the top of it.

a landfill contains leachate with a chloride concentration of 2135mg/l. the landfill has a clay liner that is 2m thick and has a tortuosity coefficient of 0.5. the diffusion coefficient for chloride is 2.3×10-⁹. after 50years what would be the chloride concentration just outside of the clay liner? assume theres no ground water gradient across the liner How long would it take for chloride to be detected just outside the clay liner at the secondary MCL of 250mg/L? Assume diffusion is the only mechanism
An MSW landfill has inactive cells covered with an intermediate cover of 1 m of sandy-loam soil. The soil is washed before use, thus it is at 100% field capacity when applied. The local 10-year average weather data is as follows.

A municipality with a population of 120,000 is under state mandate to recycle 20% of the solid waste generated by its citizens. The remaining 80% will be landfilled. The per capita waste generation rate is 2.2 kg/day. The landfilled waste in-place maximum compacted density is 820 kg/m3, and the soil-cover-to-compacted-waste ratio is 1:4 by volume. The landfill covers a rectangular area 400 m by 500 m. The maximum landfill height cannot exceed 25 m with 1:1 side slopes. What is the operating life of the landfill?
To treat solid waste generated from a town of population 80000, a landfill is designed. The per capita solid waste generation is 1.8 kg/day/person and density of compacted solid waste is 1250 kg/m3. The solid waste cover factor is 3.0. Estimate the area of landfill required in hectares for 15 years of operation. Assume depth of landfill as 5 m.
