Non-Methane Organic Compounds (NMOCs)– Method EPA25C

Fixed Gases – Method EPA 3C

Volatile Organic Compounds – EPA TO-15 & TO-14

Siloxanes – EPA TO-15

Sulfurs – EPA TO-15 (including Hydrogen Sulfide)

BTU - Calculation based on Methane (EPA3C)

Fingerprint Analysis (NMOCs) - Method EPA 18


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 landfills 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.


Our new technologies have been designed to assist with the following common landfill gas projects:


Tier II Compliance / Monitoring

WTE System Evaluation

Gas Migration Identification / Monitoring

Odor Mitigation


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 helium0charged for compliance with DOT shipping regulations. We can also provide precisely calibrated flow regulators, Teflon™ tubing, Swagelok™ fittings, and other consumables required for sampling.


If you would like more information about our landfill gas program or air testing, please contact one of our project managers today at or 804-358-8295
