Proposed ASTM standard, WK43267, Test Method for Measurement of Dissolved Gases Methane, Ethane, Ethylene, and Propane by Static Headspace Sampling and Flame Ionization Detection will help environmental and testing laboratories ensure that drinking water is safe in areas in which hydraulic fracturing occurs. Laboratories would use proposed test to compare water from fracturing areas to water prepared with dissolved gases as a serial dilution.
