Ideally, sites should be located in silt and clay soils that restrict leachate and gas movement. A landfill constructed over a permeable formation such as gravel, sand or fractured bedrock can pose a significant threat to groundwater quality.

Choosing a suitable location for landfills depends on several factors and is a complicated procedure. Multi-criteria decision making is often used for the landfill site selection. Assessments indicate that the most frequently used methods are weighted linear combination (WLC), ordered weighted averaging (OWA), analytic hierarchy process (AHP), fuzzy analytic hierarchy process (F-AHP), TODIM, fuzzy TODIM, analytic network process (ANP), fuzzy-analytic network process (F-ANP), and grey systems theory, each of which is discussed. The most widely used factors for selecting a landfill site are groundwater depth, surface water vicinity, elevation, land slope, soil permeability, soil stability, flooding susceptibility, lithology and stratification, faults, land use type, nearby settlements and urbanization, cultural and protected site vicinity, wind direction, roads, railways, proximity to building materials, pipelines and powerlines, and proximity to airports.

*Quantity of waste it will dayly receive, also taking into account population growth rate.

*Soil type, in order to protect groundwater.

*Topography (leachate movement)

*Far from household because odor may disturb.

To choose an appropriate placement for the successful completion of the technical landfill,

you must take into account:

-Soil characteristics and lithology: as you know there is a possibility of infiltration towards groundwater.

-Topography of the site: in a context where surface water is in close proximity, topography can play a role in the pollution of surface water.

-Distance from housing: the further away from housing the better.

-Activities that take place in the surrounding area.

I hope this helps.
