Bioremediation: Answer to Reduce Leachate in Landfills?

One element in class that drew my attention was learning about landfills and the major concern of environmental hazards they produce due to leachate. Because of this, i was curious in finding an answer to the leachate problem that would help this contaminant be a thing of the past. "Leachate" is any liquid that drains from land or stockpiled material and contains high concentrations of undesirable elements developed from the material that it has passed through. this problem is what allows people to question landfills especially in highly populated areas. These populated areas could be subject to water supply contamination, thus being harmful for the people who drink the water.

After surfing the Internet for a while, i came up on a process called Bioremediation. This process involves the use of micro-organism metabolism to remove pollutants. Bioremediation involves treating the contaminated material at the site, thus reducing/ eliminating the chemical impact that the contaminant may pose on any location in question. After reading the articles i posted below, i could not help but to wonder why this process is not heavily used in all landfills around the globe. The use of the micro-organisms is a method that not only holds a natural effect on the environment that has been contaminated, but, it is a cleaner, cheaper, and safer way to rid these toxic contaminants within landfills. Therefore, i believe bioremediation allows the process of waste management (in landfills) to be a better and more environmentally friendly method of getting rid of trash in populated areas. ultimately, providing an answer to solve the problem of leachate in landfill designated areas.
