Do you mean determining the location of landfills

Dear Ali,

You can refer to a guideline which is published by USEPA. Find the link here:

Yours,

Good link by Bardia Roghani,

I think Dr. Bardia Roghani provided a comprehensive guide.

Essentially ground composition plus local hydrology of water supplies and movement, are combined with public acceptability of a location.
