Toxic Metal Concentration and Distribution in Soils of Four Abandoned Landfill Sites, Springfield, Missouri
The four abandoned Springfield landfills are located in river floodplains on soluble limestone bedrock, maximizing the possibility for ground and surface water contamination by leachate. Toxic metals are present in the landfills from the disposal of everyday household items, and the two more …

An evaluation of strategic management of landfill sites: A case study of Thohoyandou Block J. landfill site, Vhembe District Municipality, Limpopo Province
… strategic management of the Thohoyandou Block J landfill site. There are limited documented materials on strategic management of landfill sites in South Africa. As a result, this study sought to close this gap and expose new insights that it deemed to be of great importance in the management and …

The effect of sewage sludge co-disposal and leachate recycling on refuse stabilization
In the past sanitary landfill sites for solid waste disposal were regarded simply as containment sites so that the waste contents were isolated from the population. Various degrees of effort were made to reduce the impact of the waste in and around the site - in some cases none in other cases …

Waste farm: a productive landscape for integrated waste management
… re-opening and licensing of Historic and Old landfill sites. The project to reassess these landfill sites is due to the fact that the three main operating landfill sites in Cape Town are nearing capacity. This calls for the city to re-imagine its waste management infrastructure. Meanwhile, …

Landfill design, construction and non-invasive monitoring
… order to assess their applicability for use in landfill design, construction and monitoring. Firstly, an assessment is made of QA procedures during liner construction through the detailed evaluation of two case studies. Construction QA procedures on-site are compared to available guidelines. The …
