      No viral indicators in any of the major recreational water 
      regulations
        Although USEPA is in the process of developing a recreational 
        water quality criteria for coliphage
      HABs (cyanobacteria and marine phytoplankton) are not 
      currently assessed as part of BWD assessment and 
      classification – but it is a requirement to consider them as part 
      of the bathing water profile and when health risks are 
      identified:
