M. Shackelford scheme now being developed will incorporate modern gas chromatography-mass spectrometry-computer techniques to identify and quantify specific organic pollutants. INTRODUCTION Every natural and synthetic organic compound can be expected to be found in some water sample if detection limits are lowered sufficiently (1). In fact, the number of organic compounds identified in water is increasing rapidly as scores of laboratories examine effluents, surface water, and drinking water for various reasons· This mass of data needs to be continually updated, classified, and computerized to allow development of analytical methodology, to permit accurate health effects studies, and to provide an accurate data base for setting and enforcing pollution regulations.
