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 ...
One method of leachate management that was more common in uncontained sites was leachate re-circulation, in which leachate was collected and re-injected into the waste mass. This process greatly accelerated decomposition and therefore gas production and had the impact of converting some leachate volume into landfill gas and reducing the overall ...
Typical BMPs include operator training, maintenance practices, and spill control procedures for treatment chemicals. [9] There are also many BMPs available which are specific to particular industrial processes, for example: source reduction practices in metal finishing industries (e.g. substituting less toxic solvents or using water-based ...
In 2021, 154,000 gallons of leachate overflowed at the facility in what may have been the largest spill in state history. Weld said the company believed the spill did not extend beyond a surface ...
Biological substances can experience leaching themselves, [2] as well as be used for leaching as part of the solvent substance to recover heavy metals. [6] Many plants experience leaching of phenolics, carbohydrates, and amino acids, and can experience as much as 30% mass loss from leaching, [5] just from sources of water such as rain, dew, mist, and fog.

Officials have positively identified the remains of a girl whose body was found hidden in brush under a plastic tarp in 1973, Pennsylvania authorities said this week. The remains belong to Ruth ...
Dec. 8, police officers and firefighters responded to the incident at around 4:30 p.m., and the 12-year-old boy's body was recovered from the water about three hours later.
Wet disposal has been preferred due to economic reasons, but increasing environmental concerns regarding leachate from ponds has decreased the popularity of wet disposal. [9] The wet method consists of constructing a large "pond" and filling it with fly ash slurry, allowing the water to drain and evaporate from the fly ash over time. [10]
