1.2 This test method has been validated in a collaborative round-robin study () and estimated detection limits (EDLs) have been determined for the analytes listed in (). Observed detection limits may vary between ground waters, depending on the nature of interferences in the sample matrix and the specific instrumentation used.

1.3 This test method is restricted to use by, or under the supervision of, analysts experienced in both the use of liquid chromatography and the interpretation of liquid chromatograms. Each analyst should demonstrate an ability to generate acceptable results with this test method using the procedure described in .

1.4 When this test method is used to analyze unfamiliar samples for any or all of the analytes listed in , analyte identifications should be confirmed by at least one additional qualitative technique.
