    The September 2002 Version of the Method 1600 Enterococcus Test: Aerococcus viridans as a False-positive Organism: Research Project Summary
    (Trenton, N.J. : New Jersey Department of Environmental Protection, Division of Science, Research and Technology, 2007) Feerst, Eric; Hovendon, Bruce; Atherholt, Thomas
    When analyzing marine bathing water samples using the September 2002 version of the USEPA Method 1600enterococcus test, Aerococcus viridans was infrequently observed as a high-rate “false-positive” organism. The USEPA intends to revise Method 1600 to eliminate the counting of blue-halo colonies less than 0.5 mm diameter, but users of the September 2002 or earlier version of Method 1600 should be aware of this false-positive issue.
