Abstract
An inappropriate landfill site may have negative environmental, economic or
ecological impacts. Landfill siting should therefore consider a wide range of
territorial and legal factors to reduce such negative impacts as far as possible.
This paper describes the application of an integrated system of landfill siting
methodology. The methodology incorporates techniques from various scientific
fields as well as GIS (Geographical Information Systems) to generate spatial data
for the evaluation of the suitability of an area for optimal landfill siting. The
resulting land suitability is reflected on a graded scale with several territorial
indexes indicating the risk and probability of contamination for five
environmental components: surface water, groundwater, atmosphere, soil and
human health. The methodology has been applied to a site in Granada (Southern
Spain).
Keywords: landfill siting, municipal waste landfill, Geographical Information
Systems, territorial siting criteria, waste management.
1 Introduction
Although authorities are attempting to reduce waste generation and disposal by
implementing recycling programs and new facilities, the sanitary landfill remains
a necessary part of the municipal waste management system [1, 2, 3].
Keywords
