In some older landfills, leachate was directed to the sewers, but this can cause a number of problems. Toxic metals from leachate passing through the sewage treatment plant concentrate in the sewage sludge, making it difficult or dangerous to dispose of the sludge without incurring a risk to the environment.
Solid waste landfills can be affected by seismic activity. The tension in a landfill liner rises significantly during an earthquake, and can lead to stretching or tearing of the material. [1] The top of the landfill may crack, and methane collection systems can be moved relative to the cover. [2]
The gas coming from the landfill can be used to evaporate leachate in situations where leachate is fairly expensive to treat. The system to evaporate the leachate costs $300,000 to $500,000 to put in place with operations and maintenance costs of $70,000 to $95,000 per year. A 30,000 gallons per day evaporator costs $.05 - $.06 per gallon.
Landfill gases have an influence on climate change. The major components are CO 2 and methane , both of which are greenhouse gases . Methane in the atmosphere is a far more potent greenhouse gas, with each molecule having twenty-five times the effect of a molecule of carbon dioxide.
The landfill’s containment systems were overwhelmed with rainwater filtering through the rotting garbage. Oxygen may have intruded below the landfill cover causing the generation of extreme heat, production of excessive leachate, and the buildup of pressure within a 35-acre closed portion (14 ha) of the site.
Wise County officials are concerned that a proposed construction waste landfill planned for a a rapidly growing near Boyd and Aurora could affect the West Fork of the Trinity River, a major water ...
“It is also possible that earthquakes can increase the stress at the continuation of the faults or nearby faults, which may trigger other earthquakes.” Does climate change affect seismic activity?
On the current rate at which carbon dioxide and other gases are building up in the atmosphere, the world will see temperature rises well beyond 1.5C.
