It is applicable to environmental waters.<\/p>\n<p>1.2 Certain types of debris and other microorganisms may fluoresce in acridine orange-stained smears.<\/p>\n<p>1.3 The test method requires a trained microbiologist or technician who is capable of distinguishing bacteria from other fluorescing bodies on the basis of morphology when viewed at higher magnifications.<\/p>\n<p>1.4 Use of bright light permits differentiation of single bacteria where reduced formazan is deposited at the polar ends.<\/p>\n<p>1.5 Approximately 10<sup>14<\/sup> cells\/mL are required for detection by this test method.<\/p>\n<p>1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use.
