2010 Bacteriological Sampling in Eleven Mile Creek and Perdido Bay using Coliscan MF
A fecal coliform count of over 200 bacteria/100 mls of water indicates the water may be unsafe for swimming.
A total coliform count over 2,400 bacteria/100 mls of water indicates swimming may be unsafe
Papermills and sugar producers discharge large amounts of organic matter which are degraded by bacteria. Many of these bacteria are in the coliform family. A pathogenic bacteria, Klebsiella pneumoniae, is a coliform and associated with wastes of high organic content. These wastes reduce the dissolved oxygen in water because the bacteria use up the oxygen.
Salinity of 0 PPT would be fresh water; sea water would have a salinity of approximately 36 PPT.
