    en.wikipedia.org/wiki/List_of_Superfund_sites_in...

    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.

  3. Electrical liner integrity survey - Wikipedia

    en.wikipedia.org/wiki/Electrical_liner_integrity...

    Since the arc testing method is not dependent on water making good contact through the leak, it is more sensitive and comparatively easy to perform in most types of liner construction (ponds, Landfills, tanks etc.)than the water-based methods. The minimum sensitivity of the arc testing bare geomembrane liner integrity method is a pinhole leak.

  4. Glen Lily Landfill - Wikipedia

    en.wikipedia.org/wiki/Glen_Lily_Landfill

    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 ]

  5. Leachate - Wikipedia

    en.wikipedia.org/wiki/Leachate

    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.

  6. Helium mass spectrometer - Wikipedia

    en.wikipedia.org/wiki/Helium_mass_spectrometer

    The vacuum chamber is connected to a vacuum pumping system and a leak detector. Once the vacuum has reached the mass spectrometer operating pressure, any helium leakage will be measured. This test method applies to a lot of components that will operate under pressure: airbag canisters, evaporators, condensers, high-voltage SF 6 filled switchgear.

  7. Fugitive emission - Wikipedia

    en.wikipedia.org/wiki/Fugitive_emission

    A detailed inventory of greenhouse gas emissions from upstream oil and gas activities in Canada for the year 2000 estimated that fugitive equipment leaks had a global warming potential equivalent to the release of 17 million metric tonnes of carbon dioxide, or 12 percent of all greenhouse gases emitted by the sector, [9] while another report put fugitive emissions at 5.2% of world greenhouse ...

  8. Landfill gas monitoring - Wikipedia

    en.wikipedia.org/wiki/Landfill_gas_monitoring

    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.

  9. Hydrologic Evaluation of Landfill Performance - Wikipedia

    en.wikipedia.org/wiki/Hydrologic_Evaluation_of...

    The Hydrologic Evaluation of Landfill Performance (HELP) model is a quasi-two-dimensional hydrologic numerical model for conducting water balance analysis of landfills, cover systems, and other solid waste containment facilities; it was developed for the United States Environmental Protection Agency.
