[Microbial growth on an expansion joint of a reservoir for drinkingwater (author's transl)].
In a clear water reservoir built in ready construction after a working-period of five months quite a lot of slime could be found on the expansion joint filled with tightening compound on the base of Thiokol. The covering slime could be removed easily with a rubber-screen. The microbiological analysis showed an extremely high number of colonies and additional the slime was secondarily settled with Protozoa. An influence on the water in the reservoir could not be found out under working conditions.
