The required US EPA methods for VOCs are US EPA Methods 524.2, 524.3, and 524.4 (Drinking Water), Method 624 (Waste Water), and Method 8260 (Groundwater and Solid Waste). US EPA Method 8260 is by far the most comprehensive in terms of the number of VOCs included in the compound list, with as many as 100 or more RCRA VOCs included for testing.
Volatile Organic Chemical (VOC) Sampling Procedure Roll or shake vial to fully mix ascorbic acid. Carefully uncap vial and add 4 drops of HCL to the vial. NOTE: HCLmay cause burns so use proper eye, hand, and clothing protection. STEP TEN Repeat steps six through nine using the second 40-ml vial.
Trace Level Determination of Volatile Organic Components (VOC’s) in packaged drinking water by HSGCMS Table 1.

VOC measurements are commonly performed using a thermal desorption-gas chromatograph mass spectrometer (TD-GC/MS). To reduce the risk of analysis failures due to the time-consuming process of sampling the atmosphere, multiple tubes are typically used for backup sampling or samples are re-analyzed using a TD restore function.
