Abstract

Groundwater samples, obtained near two underground coal gasification experiment sites, have been analyzed for phenols, cyanide, and sulfate. The samples were analyzed in the field; they were also preserved and sent to remote laboratories for analysis. Comparisons of the results have shown that the agreement between laboratory and field analyses is fairly good. This indicates that the methods of preservation are effective for these types of groundwater samples and that field analysis gives reliable information.
