This report includes the results of a pilot audit program on source emission measurement systems used to measure POHC (Principle Organic Hazardous Constituents). Four laboratories currently active in sampling and analysis of POHC during trial burns at hazardous waste incinerators were included in the pilot audit program. Two source emission measurement systems frequently used for volatile POHC measurement during trial burns were audited. These measurement systems are the volatile organic sampling train (VOST) and bag measurement technique. The audits were conducted using gas cylinders containing five organics (carbon tetrachloride, chloroform, perchoroethylene, vinyl chloride and benzene). Results from the pilot audit program demonstrate gas cylinders are a very effective means of assessing accuracy of volatile POHC measurement systems. Audit results are reported in the report.
