ABSTRACT

Dissolved gases in water can originate from a number of sources. It can stem from rock formations, from decomposition of organic material or be produced by microbes. No matter where the dissolved gases come from, they can be hazardous both to the environment and to humans. The RSK-175 SOP was developed to test for dissolved light gases through static headspace sampling. Since RSK-175 is a standard operating procedure and not a formal method, there have been many interpretations of the procedure. The ASTM standard D8028 was proposed to quantitatively determine dissolved light gases in ground waters, waste waters, and drinking waters. This presentation will discuss ASTM Method D8028, what steps were taken to develop the method and where the method stands currently.
