Determine leachate generated in a cell in a $12-$month period. You may assume that:

$-$Percolation through the cover is $15$ in

$-$Water consumed by waste decomposition is negligible $($Life $1$ contains mostly fresh waste$)$

$-$Water loss as water vapor in landfill gas is negligible $($again due to fresh waste$)$

$-$Initial moisture content in fresh waste $=0\mathrm{.}20$

$-$Weight of waste in the lift $=3000l\frac{b}{y}{d}^2$

$-$Weight of cover $=1500l\frac{b}{y}{d}^2$

$-$The following sketch depicts water in and out of a waste lift.
