Managing Daily Cover and Drainage at MSW Landfill Sites

Today’s municipal solid waste (MSW) landfills are much more than places to dump household trash. They’re engineered facilities that are designed to hold and isolate the trash from the environment and are governed by both federal and state regulations.

Landfill designers and operators face two main challenges to the integrity of

Soils may become degraded during the construction of buildings, roadside projects, or mining or landfill operations, or because of overgrazing or deforestation. They lose their topsoil, usually the top 2- to 8-inch layer of the soil, where the most important nutrients lie.

Increasing Machine Utilization With Attachments

Industry experts agree: using a piece of compact ­equipment with multiple attachments turns that one machine into a multipurpose tool for road construction site preparation work that can help contractors complete their jobs more efficiently, bid on larger projects, create a more diversified portfolio, and work in all weather and

The Science of Seeds

The Science of Seeds

Remember how 10 blindfolded people in a room each describe the elephant from their own perspective? The same might be said of soil—the stuff we interchangeably refer to as ground, dirt, or surface covering. Eric C. Brevik, a professor of soil science at Dickinson State University in North Dakota, illustrates

Insights From the Journey

Insights From the Journey

One of the great gifts of writing is the knowledge that one gains from the research necessary to create intelligent composition. My high school English teacher—who also taught Kurt Vonnegut—once told me that there were seven basic plots in literature and not to worry about outlining a wholly original narrative,

Wildfires: Challenges in Revegetation

Wildfires: Challenges in Revegetation

It was the setting for a perfect disaster: historic level droughts, acres of dry forest and grassland, huge reserves of dead wood fuel, and a hurricane that sucked any moisture from the air. Locals said it was just “powder-keg dry.” Implementing a revegetation plan after a wildfire is a challenge;
