| Abstract |
This report provides results produced by VOA grab and composite sampling procedures in studies conducted by the U.S. Environmental Protection Agency (EPA) in early 1994. In these studies, four individual grab samples of real-world effluents were collected over the course of a day. These were analyzed spiked or unspiked, composited and individually, by isotope dilution GC/MS, using Revision C of EPA Method 1624. Both manual and automated grab sampling procedures were employed. Compositing procedures employed included flask, purge device, and continuous. Analytes spiked were the volatile organic GC/MS fraction of the priority pollutants plus additional compounds routinely tested for in EPA's industrial surveys. The ojective of these studies was to compare the analytical results for manually collected individual grab samples to the analytical results for composited samples and automatically collected grab samples, to determine if bias occurred in the automated grab and compositing processes. |
