In 2004, the landfill was reorganized as a controlled disposal facility [4] and was closed in December 2010. [9] A separate landfill with a stricter waste management policy was established nearby the old open dumpsite [1] in January 2011. [9] Garbage in the dumpsite was dumped on a layer of tarpaulin to prevent seepage of leachate to the ...
Toxicity characteristic leaching procedure (TCLP) is a soil sample extraction method for chemical analysis employed as an analytical method to simulate leaching through a landfill. The testing methodology is used to determine if a waste is characteristically hazardous, i.e., classified as one of the "D" listed wastes by the U.S. Environmental ...
A number of complex organic contaminants have also been detected in landfill leachates. Samples from raw and treated landfill leachate yielded 58 complex organic contaminants including 2-OH-benzothiazole in 84% of the samples and perfluorooctanoic acid in 68%. Bisphenol A, valsartan and 2-OH-benzothiazole had the highest average concentrations ...
The Clark Sanitary Landfill began operations in 2002. [2] The landfill's managing company, the Metro Clark Waste Management Corp. (MCWM) was incorporated on the same year. [6] Upon starting operations, the dumping facility became the first engineered landfill in the Philippines. [7] The landfill cost $215 million. [8]
The dumpsite was reopened weeks later by then-Quezon City Mayor Ismael Mathay Jr. to avert an epidemic in the city due to uncollected garbage caused by the closure. [6]The landslide prompted the passage of Republic Act No. 9003 or the Ecological Solid Waste Management Act of 2000, [7] which mandates the closure of open dumpsites in the Philippines by 2004 and controlled dumpsites by 2006.
Once a landfill site is full, it is sealed off to prevent precipitation ingress and new leachate formation. However, liners must have a lifespan, be it several hundred years or more. Eventually, any landfill liner could leak, [7] so the ground around landfills must be tested for leachate to prevent pollutants from contaminating groundwater.

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.
