Microbiological Causes of Tastes and Odors in Laramie's Drinking Water
Abstract
Blooms of algae tentatively identified as Asterionella and
Anabaena occurred at times when tastes and odors developed in the surface
water source of Laramie's drinking water during the summer of 1984.
Actinomycetes were found in Laramie's surface water source but did not
appear to be numerous enough to be responsible for the tastes.
Filamentous algae did not become numerous enough to present a problem at
the wastewater treatment facility during the summer of 1984. Selected
bacteria were enumerated through the surface water treatment plant
during the summer of 1984. This plant reduced numbers of bacteria from
raw to finished water by 99.99 percent. Fecal coliforms survived for
three months in material taken from the sedimentation basins. In some
cases R2A medium was the superior medium for determining the heterotrophic
plant count.
