The rate of percolation into a 12-m deep landfill is 248 mm/y. The refuse (i.e., waste) field capacity is 305 mm/m and the moisture content of the refuse is 180 mm/m. Calculate how many years it will take for the moisture front to move through the landfill and produce leachate. Round your answer to one term past the decimal point.

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.
