Site selection for hazardous waste landfill and routing analysis for hazardous waste transportation using Geographic Information System at Changwat Khon Kaen

Abstract

The aim of this study is to identify a suitable site for constructing a hazardous waste landfill within Khon Kaen Province. A geographic information systems (GIS) software package was used to analyze various data sources in identifying and selecting a suitable landfill site. To identify potential areas, several factors including water resources, geology, sensitive area, community area, and other related factors were analyzed based on modified criteria for hazardous waste landfill from the Pollution Control Department (PCD), Thailand. To select a suitable landfill site, only potential areas having size large enough to be used for 20 years and a shortest distance for transporting hazardous waste from generators to the potential areas were considered. Results from the study revealed that eighteen potential areas were found within Khon Kaen Province. While, the first five least transport distances between generators and potential site were at site 6 in Tambon Muang Wan, Amphoe Nam Phong, site 7, site 9, site 8, and site 10 in Tambon Khok Song, Amphoe Ubonrat which the distance of 1223.52, 1225.99, 1245.12, 1288.35, and 1350.90 kilometers, respectively.
