EPA's Master Analytical Scheme (MAS) for Organic Compounds in Water provides for comprehensive qualitative-quantitative analysis of gas chromatographable organics in many types of water. The paper emphasizes the analysis of polar and ionic organics, the more water soluble compounds in the MAS repertoire, in raw and treated drinking water. Mean recoveries from drinking water using the MAS protocols that handle polar and ionic compounds were: 84% for neutral water soluble organics (25 compounds spiked at 1 ug/l), 89% for extractable semivolatile strong acids (24 compounds spiked at 50 to 100 ug/l), 82% for volatile strong acids (18 compounds spiked at 0.3 ug/l), and 81% for strong primary and secondary amines (11 compounds spiked at 35 ug/l). The protocol for nonvolatile acids has not yet been applied to spiked drinking water, but recoveries should be higher than the average of 85% (14 compounds spiked at 50 ug/l) obtained for these acids in industrial-municipal effluents.
