Background and Objective: Improper landfilling of drilling waste has adverse effects on the environment and human health. This study aims to select suitable landfills for oil and gas drilling waste on Qeshm Island using GIS and AHP.
Materials and Methods: In this study, a weighted map was prepared based on each criterion affecting the site location. In the next step, each of the prepared layers was ranked. Higher rating indicated the importance of each layer while lower values corresponded to their insignificane.
Results: The reasults of this study showed that the distance from population centers (weight 0.222), communication network (roads) (weight 0.169) and surface waters (weight 0.142) are important parameters for landfill siting. The combination of ranked maps and the weights obtained from AHP, divided the landfill area to “completely suitable”, “suitable”, “relatively suitable”, “relatively unsuitable” and “unsuitable”.
Conclusion: Priorities identified in “completely suitable” areas can be the basis for decision-making, and appropriate locations can be on the agenda as next priorities.
