Landfill Leachate to Be Disposed of in Zhuhai

A project was launched Friday May 5, 2010 in Zhuhai city, southern China's Guangdong Province to correctly get rid of the leachate create at a chief landfill. The Xikengwei landfill is responsible for collecting most of the urban garbage of Zhuhai but does not have the resources to deal with the leachate. The landfill was put into operation in November 2007 and the leachate has become dangerous as it contains high density of organic materials and heavy metal salts. The project is looking to treat 1,000 cubic meters of the hazardous toxin created from the decay of waste inside the landfill. It cost about 13.6 million American dollars and is expected to be completed by the end of August.


RuCo works to fix toxic leak at county landfill

A silent yet serious problem at the Rutherford County Landfill has popped up involving leachate and other dangerous landfill toxins The Solid Waste Management Division of the Tennessee Department of Environment and Conservation has partnered with several organizations including Rutherford County officials in an attempt to solve the problem. Several people detected waste constituent in the county landfill’s ground water monitoring system, but none of the detected constituents surpass the narrow utmost contaminate levels.

Leachate is created from the mixture of water when it comes in contact with cement kiln dust. Cement kiln is a waste product and in this case was created underneath sections of the resort corridor from the years when a cement plant operate in the area. Petoskey’s wastewater treatment plant is considering offering a effective alternative for disposing of toxins collected in the ecological cleanup at Bay Harbor, city staff and consultants told the Petoskey City Council Wednesday. Leachate is just one of several toxins being discussed and the decision could be dire for the environment.

The video discusses the hazardous materials that are smuggled into landfills. The material could prove very hazardous as the composition of leachate is dependent on the materials found in landfills.

Typical Leachate is composed of of nitrogen, iron, organic carbon, manganese, chloride and phenols, yet the composition varies from site to site. The degree in severity of Leachate in dependant on the composition of the material in dump sites. Rainwater leaking into dump sites causes the mixture of several chemicals in a dumpsite and eventually the creation of Leachate. Leachate refers to landfill leachate inside the waste management industry and outside. Yet leachate is also used when referring to the liquid created when water penetrate through any permeable substance.

Several conflicts arise when dealing with Leachate. In many cases Leachate is harmless for its composition is dependent on the material in landfills. Yet in many cases Leachate becomes toxic. Leakage of Leachate in the environment can be dangerous for wildlife and it can be very hazardous to the human population. Ground water accounts for 40 percent of the world’s drinking water. 40 percent of the world depends on ground water as a drinking source. That percentage includes millions of people; millions of people who are potentially at risk. When Leachate leaks into the environment it can potentially contaminate ground water and the results are catastrophic.

Modern day landfills are equipped to deal with the leachate problem as they have been built with the proper systems in order to collect and dispose of Leachate. They are designed with a slope, usually at about 3 percent, so that liquids leak into collection sumps. These collection sumps include a riser called HDPE and pump. Leachate drains to the leachate collection system, and then drained to an onsite leachate storage tank. The leachate is transported to an standard wastewater treatment plant for discarding. The systems vary from landfill to landfill, yet the basics are same and usually there is not much conflict when dealing with Leachate. Yet conflict does arise when the disposal process is neglected. There have been several cases where landfills have been disregarded standard procedure when dealing with toxins and the margin of error increases significantly. In many cases leachate has leaked after being unattended to while in storage. A prime example of that would be that of A Mr. Monroe Branstad who was charged with putting the health of the environment at risk. Leachate was just one of several toxics that Bandstand neglected to manage and dispose of and as a result the biological waste leaked into the environment. The outcome of his negligence were dreadful and the pollution maybe long term. His tardiness is said to be a direct cause of the death of thousands of fish in the Winnebago River along a 16 mile stretch. Mr. Monroe Branstad has been ordered to pay 17,000 by a court for his action. This is just one of several cases concerning leachate and in each case the environment was put at risk. So the ultimate responsibility falls upon landfill owners and those who manage Leachate. The responsibility of properly dealing with the hazardous toxins falls upon humanity and only humanity. Increase awareness about the potential effects of leachate would be a positive step in dealing with it and so I create a write up discussing Leachate and its effects and sent it to nearby landfills and dumpsite workers in my community. I also took a trip to the Waste Management in Columbus, New Jersey and interviewed workers on toxins and Leachate specifically. The information went in my write up and allowed me to create a concise, informative text to send to the dumpsites

Closed landfill may tempt owners

Summary: Quail Hollow Landfill was closed down on Dec. 12, 2003 when about 20,000 gallons spilled from one of its tanks and into the environment. The result of the spill is still being recorded today and there have been several drastic changes as a result of the spill. Several conflict have arisen from the landfill, yet Leachate leakage is one of the most significant.

A Mr. Monroe Branstad has been accused of endangering the environment and has been ordered to pay 17,000 by a court for his action. Leachate was just one of several toxics that Bandstand failed to properly manage and dispose of and as a result the biological waste leaked into the environment. The result if his tardiness were horrific and the pollution maybe long term. It is said that the pollution caused of the death of thousand of fish in the Winnebago River along a 16 mile stretch.

Contractors were regularly dumping hazardous liquids, in many cases, leachate, across the city into the public sewer from where it flowed to a treatment plant in Ringsend.

Council workers have been prohibited from dumping toxic waste into a Phoenix Park sewer after the issue was brought into the light by the Herald.
