Assessment of groundwater quality around municipal solid waste Landfill by using Water Quality Index for groundwater resources and multivariate statistical technique: a case study of the Landfill Site, Qaem Shahr City, Iran
Environmental Geochemistry and Health, 2019Co-Authors: Hossein Najafi Saleh, Sima Valipoor, Asma Zarei, Mahmood Yousefi, Farzaneh Baghal Asghari, Ali Akbar Mohammadi, Fazzel Amiri, Sahar Ghalehaskar, Amin Mousavi KhaneghahAbstract:Groundwater is a precious natural water resource which can be considered as an available and safe source of water for domestic uses. In some cities in northern Iran, groundwater is being polluted due to various human activities. In this regard, the located municipal solid waste Landfills close to these areas without the requested controls regarding the Landfill leachate and gas emission are among the major sources of environmental pollution, which are deteriorating groundwater quality around Landfill Sites. In this context, the current study was aimed to assess the quality of collected groundwater samples around a Landfill Site using the modified Water Quality Index for groundwater resources (WQIG). Also, the water quality map has been prepared by using WQIG in GIS environment. Therefore, thirty-three groundwater samples were collected and analyzed around 11 water wells close to the Landfill Site. Variety of physicochemical parameters including nitrate (NO_3), fecal coliform, sodium absorption ratio (SAR), electrical conductivity, biological oxygen demand (BOD_5), phosphate (PO_4), total dissolved solids, dissolved oxygen, pH were assessed in groundwater samples based on recommended standard methods by American Public Health Association (APHA). Geostatistics analysis including Kriging, semi-variogram, and variogram methods also was used to evaluate the spatial variations in the variables and to provide the necessary data for further interpolation. According to the results of WQIG, most of the groundwater wells (98.85%) are polluted due to the existing of the Landfill Site in the investigated area. Generally speaking, based on the WQIG the water samples were defined as not suitable for drinking applications. Also, the high concentrations of nitrate and hardness in the downstream wells (W_1–W_11) of the Landfill were demonstrated by the results of Kriging assay which can be correlated with the penetration of leachate into these wells. Considering the SAR results, all wells in the studied area are classified as (C_3S_1) that means the groundwater of this area is suitable for agricultural approaches. Moreover, the reduction in the water quality from the south to the north and northeast was demonstrated by the results of spatial dispersion. Evaluation of the changes in water quality near Landfill Sites showed that 2149.56 m^2 of total area had a relatively poor potential for the region’s groundwater recharge.

integrating multi criteria evaluation techniques with geographic information systems for Landfill Site selection a case study using ordered weighted average
Waste Management, 2012Co-Authors: Pece V. Gorsevski, Katerina R. Donevska, Cvetko D Mitrovski, Joseph FrizadoAbstract:This paper presents a GIS-based multi-criteria decision analysis approach for evaluating the suitability for Landfill Site selection in the Polog Region, Macedonia. The multi-criteria decision framework considers environmental and economic factors which are standardized by fuzzy membership functions and combined by integration of analytical hierarchy process (AHP) and ordered weighted average (OWA) techniques. The AHP is used for the elicitation of attribute weights while the OWA operator function is used to generate a wide range of decision alternatives for addressing uncertainty associated with interaction between multiple criteria. The usefulness of the approach is illustrated by different OWA scenarios that report Landfill suitability on a scale between 0 and 1. The OWA scenarios are intended to quantify the level of risk taking (i.e., optimistic, pessimistic, and neutral) and to facilitate a better understanding of patterns that emerge from decision alternatives involved in the decision making process.

Regional non-hazardous Landfill Site selection by integrating fuzzy logic, AHP and geographic information systems
Environmental Earth Sciences, 2012Co-Authors: Katerina R. Donevska, Pece V. Gorsevski, Milorad Jovanovski, Igor PeševskiAbstract:This study presents a geographic information systems-based multi-criteria Site selection of non-hazardous regional Landfill in Polog Region, Macedonia. The multi-criteria decision framework integrates legal requirements and physical constraints that relate to environmental and economic concerns and builds a hierarchy model for Landfill suitability. The methodology is used for preliminary assessment of the most suitable Landfill Sites by combining fuzzy set theory and analytic hierarchy process (AHP). The fuzzy set theory is used to standardize criteria using different fuzzy membership functions while the AHP is used to establish the relative importance of the criteria. The AHP makes pairwise comparisons of relative importance between hierarchy elements grouped by environmental and economic decision criteria. The Landfill suitability is achieved by applying weighted linear combination that uses a comparison matrix to aggregate different importance scenarios associated with environmental and economic objectives. The results from the study suggested that a least suitable Landfill area of 1.0% from the total is generated when environmental and economic objectives are valued equally while a most suitable Landfill area of 1.8% area is generated when the economic objective is valued higher. Such results are aimed for enhancement of regional Landfill Site selection in the country that is compliant with modern EU standards.

sustainable Landfill Site selection for municipal solid waste based on a hybrid decision making approach fuzzy group bwm multimoora gis
Journal of Cleaner Production, 2020Co-Authors: Saleheh Rahimi, Ashkan Hafezalkotob, Seyed Masoud Monavari, Razieh RahimiAbstract:Abstract This paper introduces a framework comprising Geographic Information System (GIS) techniques and fuzzy Multi-Criteria Decision-Making (MCDM) methods for application in Landfill Site selection problem. The developed methodology is utilized in an environmentally critical area related to Mahallat city located in the northwest of Iran. In this process, fourteen effective parameters related to sustainability of the location of Landfills are identified and categorized into three groups including environmental, economic, and social criteria. First, criteria weights are obtained by applying the group fuzzy Best-Worst Method (BWM) and then suitability maps are generated based on GIS analysis. From the spatial analysis, eleven potential Sites are identified as the most suitable alternatives. These Sites are then analyzed and ranked using group fuzzy MULTIMOORA method. This study is different from the previous researches applied the GIS-MCDM approach, in that group fuzzy BWM for weighting criteria is more reliable compared to the other common methods. The group fuzzy MULTIMOORA method, and its three subordinate approaches, select a same candidate, “Site A8” a region near urban area of Mahallat, as the most suitable location for disposing municipal solid waste.
