A-Tech conducted a Methane Survey to assess any potential impacts at the Starlight and Scale House Sites resulting from potential landfill methane vapor intrusion. The chemicals of potential concern were Volatile Organic Compounds and Methane.
A-Tech used direct reading instruments including a MultiRAE 5-Gas meter to measure Oxygen, Hydrogen Sulfide, Volatile Organic Compounds, and Carbon Monoxide. A-Tech also used an RKI Eagle 2 to measure Methane concentration, and percent Lower Explosive Levels.
A-Tech field personnel collected air samples from inside and outside the buildings using four (4) 6-Liter Summa canisters with flow regulators calibrated to 24 hours.
