site selection is an important and necessary issue for waste management in fast-growing regions. because of the complexity of waste management systems, the selection of the appropriate solid waste landfill site requires consideration of multiple alternative solutions and evaluation criteria. this paper addresses the sitting of a new landfill using a multi-criteria decision analysis (mcda) and o...

Landfill selection in an urban area is a critical issue in the urban planning process because of its enormous impact on the economy, ecology and the environmental health of the region. With the growth of urbanization as well as the desire to live in cities, lager amount of wastes are produced and unfortunately the problem gets bigger everyday. With the development of Geographic Information Syst...

In this study the concept of biofilm accumulation in the sand column was promoted to assess the changes in hydraulic conductivity and concentration of organic contaminants of the synthetic leachate. Four different combinations of column study were carried out using synthetic leachate as a substrate solution. Mixed and stratified mode of experiments with two different sizes (0.3 mm and 0.6 mm) o...

The purpose of the paper is to assess the groundwater quality near the landfill sites using landfill water pollution index (LWPI). In order to investigate the scale of groundwater contamination, three landfills (E, H and S) in different stages of their operation were taken into analysis. Samples of groundwater in the vicinity of studied landfills were collected four times each year in the perio...

The disposal of the solid wastes in landfill sites should be properly monitored by analyzing samples from soil, water, and landfill gases within the landfill sites. Nevertheless, ground monitoring scheme requires intensive efforts and cost, and sometime it is difficult to be achieved in large geographic extent. Remote sensing technology has been introduced for waste disposal management and moni...

The most common means for disposing of municipal solid waste is burial in a sanitary landfill. However, many landfill are underestimate the total cost of landfill disposal be considering only land and operating costs, ignoring external physical and social costs associated with landfills. This paper pro0oses and approach be estimating (in monetary terms) the external costs arising from the devel...
