  2. 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.

    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.

  4. Gas detector - Wikipedia

    en.wikipedia.org/wiki/Gas_detector

    A gas detector can sound an alarm to operators in the area where the leak is occurring, giving them the opportunity to leave. This type of device is important because there are many gases that can be harmful to organic life, such as humans or animals. Gas detectors can be used to detect combustible, flammable and toxic gases, and oxygen depletion.

  5. 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 ]

  6. Landfill gas monitoring - Wikipedia

    en.wikipedia.org/wiki/Landfill_gas_monitoring

    Thermal deactivation of CO 2-reducing microbes has been used to produce CO 2 (rather than methane) from municipal solid waste (Yu, et al., 2002). Collection System Monitoring is used to check the characteristics of landfill gas being collected by the gas extraction system. Monitoring may be done either at the individual gas extraction well or ...

  7. 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.

  8. Flame ionization detector - Wikipedia

    en.wikipedia.org/wiki/Flame_ionization_detector

    Flame ionization detectors are used very widely in gas chromatography because of a number of advantages. Cost: Flame ionization detectors are relatively inexpensive to acquire and operate. Low maintenance requirements: Apart from cleaning or replacing the FID jet, these detectors require little maintenance.

  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.
