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 ...
But leachate – the liquid that drains from the landfill – still needs to be dealt with to remove chemicals, pollutants and toxins that could harm the environment.
In Rochester, a landfill run by Waste Management of New Hampshire had at least 13 leachate discharges between the end of December 2022 and late April of this year, according to a May letter from ...
Leachate Collection and Removal Systems - sit on top of the composite liner and removes leachate from the landfill for treatment and disposal. [5] Operating Practices - including the compacting and covering of waste frequently with several inches of soil to help reduce odor; control litter, insects and rodents; and protect public health.

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.
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 ...
The landfill gas can also be sold off-site and sent into natural gas pipelines. This approach requires the gas to be processed into pipeline quality, e.g., by removing various contaminants and components. [9] Landfill gas can also be used to evaporate leachate, another byproduct of the landfill process.
Leachate water frequently has elevated levels of tritium compared to background groundwater and a leachate (water) release would increase tritium levels in affected groundwater samples, while landfill gas has been shown not to do so. Although landfill gas components can react with minerals and alter inorganic constituents present in groundwater ...
