Your community is going to build a second landfill, and some of the residents are concerned about waste contaminating the water supply. Your community has two main water supplies: a large lake reservoir that is fed by smaller streams, and an aquifer, which is an underground storage area for water. The three proposed locations for the landfill are listed below. In which location would the landfill be the least harmful to your community's water supply?

• Adjacent to the community's primary water reservoir.

• A flat area that has many layers of soil and is well above the aquifer.

• At the top of a large hill with several steams around its base.

• None of these. Landfills are bad for the environment.
