Thirteen analytical methods covering 36 analytes which may be present in a variety of environmental sample types are described in detail. Three of these methods are sample preparation procedures that require a separate determinate step found in other methods in the manual or elsewhere. These methods involve a wide range of analytical instrumentation including inductively coupled plasma (ICP) atomic emission spectroscopy (AES), ICP mass spectroscopy (MS), atomic absorption (AA) spectroscopy, ion chromatography (IC), high performance liquid chromatography (HPLC), and gas chromatography (GC). Application of these techniques to a diverse group of sample types is a somewhat unique feature of the manual. Sample types include waters ranging from drinking water to marine waters as well as industrial and municipal waste water. Methods are also included that will accommodate biological tissues and sediments and soils. Providing a set of comprehensive methods that are applicable to the widest variety of environmental samples and EPA regulatory programs is likely to become more pronounced in the future.
