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 ...
This is a list of Superfund sites in Kentucky designated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) environmental law. The CERCLA federal law of 1980 authorized the United States Environmental Protection Agency (EPA) to create a list of polluted locations requiring a long-term response to clean up hazardous material contaminations.

Phase III investigations aim to delineate the physical extent of contamination based on recommendations made in Phase II assessments. Phase III investigations may involve intensive testing, sampling, and monitoring, "fate and transport" studies and other modeling, and the design of feasibility studies for remediation and remedial plans.
In a 2012 survey performed in New York State, all surveyed double-lined landfill cells had leakage rates of less than 500 liters per hectare per day. Average leakage rates were much lower than for landfills built according to older standards before 1992.
The Glen Lily Landfill is an inactive municipal solid waste landfill located in unincorporated Warren County, Kentucky northwest of the city of Bowling Green. The landfill accepted residential and industrial waste from 1975 to 1979; [ 1 ] after being idled, carcinogenic pollutants were found to be leaching into nearby groundwater . [ 2 ]
An environmental audit of the site in 2003 found PCBs in the sediment surrounding the area, and further testing was ordered. In December 2008, EPA inspectors found about four dozen rusted metal drums on land just outside the part of the dump that it capped and fenced in the 1980s, including a portion of Jefferson Memorial Forest .

Monitoring of the landfill gas itself can be used diagnostically. When there is concern regarding the possibility of an ongoing subsurface oxidation event, or landfill fire, the presence in the landfill gas of compounds that are more stable at the high temperatures of such an event (above 500 °C) can be evidence for such a process occurring.
