The most widely used factors for selecting a landfill site are groundwater depth, surface water vicinity, elevation, land slope, soil permeability, soil stability, flooding susceptibility, lithology and stratification, faults, land use type, nearby settlements and urbanization, cultural and protected site vicinity, …
What criteria are used to select landfill sites?
Many criteria, including land cost, waste production centers, site capacity, road access, railways, airport, and archaeological heritage, soil types, landfill lifespan and public acceptance should also be considered in the landfill siting.
What are the criteria for land filling?
Criteria for Selection of Land fill Site
- Land area and volume should be sufficient enough to provide landfill capacity so that the projected need can be fulfilled for several years. …
- The landfill site should not be at locations where suitable buffer zones between land fill site and population are not available.
What are the minimum requirements you need to consider for a sanitary landfill?
1. The facility shall be a minimum 50 meters away from any perennial stream, lake or river. 2. The site shall be evaluated for presence of geologic hazards, faults, unstable soils, its foundation stability, and its hydrogeologic character.
What factors are to be considered before selecting the method of solid waste disposal?
The following may be considered when developing your evaluation criteria: cost effectiveness; time frame; reliability; environmental impact; adaptability; financing requirements; regional application and transportation; ability to meet regulatory requirements; local conditions; public acceptance; and basic siting …
What would be the most important aspect for the environment to consider in locating the landfill?
In order to select suitable site for landfill several important criteria, such as geology/hydro geology, land use, slope, aspect and distance from settlements, surface water body, roads, railway, streams, and protected areas were chosen according to standards and regulations.
What are the basic parts of a landfill that must be part of the construction?
There are four critical elements in a secure landfill: a bottom liner, a leachate collection system, a cover, and the natural hydrogeologic setting. The natural setting can be selected to minimize the possibility of wastes escaping to groundwater beneath a landfill. The three other elements must be engineered.
What factors must be kept in mind while dumping waste in landfills?
Protection of land, air, ground and surface water from pollution. Rational use of land, as well as save land (increased levels of waste compaction using special machines, as well as a deposition height)
What is landfill process?
A landfill is an engineered method for land disposal of solid and hazardous waste. Landfilling is the term used to describe the process by which solid waste is placed in the landfill. Landfills for individual waste constituents such as combustion ash, asbestos and other similar wastes are known as monofills.
What is the minimum depth of the landfill required *?
What is the minimum depth of the landfill required? Explanation: Sites should be selected where the soil can be excavated to a minimum depth of 1.8 m. Clay-like soils or any soil that can form a seal over the compacted refuse can be acceptable.
Who sets the standards by which states are to manage hazardous waste?
EPA regulates household, industrial, and manufacturing solid and hazardous wastes under the Resource Conservation and Recovery Act (RCRA).
What are three features of a sanitary landfill?
Landfills comprise a bottom liner made from clay and durable synthetic plastic; a leachate collection system to remove liquids; a stormwater management system that keeps surface water from flowing into the garbage; and a methane collection system that removes landfill gas as it is generated.
What are the factors that need to be considered in waste segregation?
These are: 1) culture, knowledge, and microeconomics; 2) infrastructure, social provisions, and technology; and 3) policy, institutions, and macroeconomics.
What are the factors that have to be considered while fixing collection route?
The parameters considered for route opti- mization are population density, waste generation and composi- tion, road networks, road length, collection vehicle speed, travel time, traffic direction, vehicle access, characteristics of waste containers and vehicles, which are depicted in Figure 3.
What are the key factors that is applied to successfully establish an in integrated solid waste management system?
The four components or functional elements of ISWM include source reduction, recycling and composting, waste transportation and landfilling.
