AWWA JAW6137

A modified Grob closed-loop-stripping device is currently being used to concentrate organic contaminants from drinking water. The identification and quantification of organic contaminants at the nanogram per liter level are accomplished by a computerized glass capillary gas chromatography-mass spectrometry system. Applications of closed-loop-stripping analysis for monitoring water by water utilities, for studying the use and the effects of alternative disinfectants in drinking water, and for providing data on the removal of organic contaminants from water by granular activated carbon treatment are discussed. Sampling, carbon filter extraction, analytical blanks, recovery studies, epidemiological studies, halogens, and trace organics are covered. Includes 27 references, tables, figures.
