the cost of the land the location of the groundwater the proximity to an industrial park the accessibility to a major highway
I gave my students this multiple choice question: Your community is planning to build a new sanitary landfill. In locating the landfill, which is the most important environmental consideration?

Only one answer is correct among these 4 choices:
- the cost of the land
- the location of the groundwater
- the proximity to an industrial park
- the accessibility to a major highway

Could you tell me which one is correct?

the location of the groundwater
