Proponents of deep well injection of hazardous wastes argue that it will never be economically feasible to pump water out of aquifers more than one kilometer below the surface. Therefore, they say, we might as well use those aquifers for hazardous waste storage. What do you think? Why?

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.
