Samples from monitoring wells indicate that a plume of contaminants migrate under a dump. The plume has progressed 50 m from the edge of the dumping ground and has a width of 80 m. We can assume that the plume is rectangular in shape. The sandstone aquifer at medium thickness (depth) of 300 m and can withstand a maximum pumping rate of 5,000 m3 / d. Determine where to place the well extraction to capture all the plume. The hydraulic gradient of the aquifer is 0.03 m / m. Provide a diagram of the capture area and show all the work

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.
