    7.2 Guidelines for management of blue-green algae in contact recreation
        areas
    When cyanobacteria (blue-green algae) is present in large amounts it can present a significant hazard, particularly
    to primary contact users of waters. National guidelines for managing risks in recreational water were released in
    2008 by the National Health and Medical Research Council (NH&MRC) and these cover cyanobacteria. The
    national guidelines for cyanobacteria have been adopted for Queensland waters and supersede previous state
    guidelines issued by the former Department of Natural Resources and Water. A summary of the national guideline
    values that replace previous state values is provided below in Table 7.2.1.
