Landfill Gas Analytical Program

In August of 2016 the EPA released its final updates to the New Source Performance Standards (NSPS) for reduction of emissions of landfill gas at new and existing landfill across the United States. As the EPA and state regulatory agencies have updated the NSPS and Emission Guidelines (EG), Air Water & Soil Laboratories, Inc. recognized the growing need for landfill gas analytical services for both compliance and internal monitoring purposes.

Analytical methods

Whether you are performing Tier II sampling, evaluating gas quality for waste-to-energy uses, or tracking a gas migration issue, AWS can help. We have established the following analytical methods in order to provide the most comprehensive landfill gas capability possible:

  • Total Non-Methane Organic Compounds (NMOC): EPA 25C Method

  • Fixed Gases: EPA 3C Method

    • Hydrogen, Nitrogen, Oxygen, Carbon Monoxide, Carbon Dioxide, Methane

  • Volatile Organic Compounds (VOCs): EPA TO-15 Method

  • Sulfurs (including Hydrogen Sulfide): EPA TO-15 Method

  • Siloxanes: EPA TO-15 Method

  • Petroleum Hydrocarbons: EPA 18 Method

  • BTU: ASTM D3588 Method

Silonite Canisters

Our Entech™ Silonite canisters are routinely monitored to ensure that your samples will not leak, suffer atmospheric contamination, or degrade as a result of faulty internal conditions. Additionally, we can provide our canisters at full vacuum or partially charged for compliance with DOT shipping regulations.
