Flashcards in Landfills - Test II Material Deck (21):
A mixture of a listed waste and a solid waste is considered a listed waste
Any waste generated from treatment, storage or disposal of a liquid waste remains listed
Any soil, groundwater or other material containing a HW must be managed as a HW
1. Type of waste?
2. Phase of waste?
3. Who will the disposal site serve?
4. What is the site capacity?
- Ac based on the area sericed by the facility
- Recycling must be considered in landfill area cal.
- How deep/high will the landfill waste be buried?
Landfill Area - Estimate Calculation
A = (27 V N ) / d
Defines the elevation of the deepest level of excavation at different areas of the landifll footprint
Usually calculated w/ the Darcy Equation and media are oversimplified as homogenous materials
Polymer can be melted and on cooling it nearly reverts to its original structure
Polymer that can be processed only once, bc further processing degrades the material
Permeable geosynthetics composed of textiles
Used for reinforcement
Nonwoven geotextiles used for
Textile formed by extruding molten polymer
Textile formed by extruded polymer twisted together
Textile formed by extruding continuous sheets that are the cut
Geosynthetic materials that have large open spaces between ribs, primarily used for reinforcement
Corridors are provided for lateral and vertical migration of gases under natural pressure and convection gradients
gas movement is induced by negative pressure applied to the system
General purposes of GW Monitoring
- Monitor linear integrity
- Monitor runoff infiltration
- Monitor GW flow
- Early detection of leaks
- Hydrologic info
