Abstract: Bacterial colony counts and TSS in karst w ater of uojin Cave, Guilin, w ere measured before, during
and af ter the rain to determine the transport and attenuation of microbe in karst aquifer systems.It showed that quali-
ty of ground water responded quickly to that of surface w ater, because the bacterial colony counts in ground w ater and
surface w ater w ere in the same order of magnitude during the given period.The variation of bacterial colony counts in
karst water was in consistence w ith that of TSS, which illuminates that bacterium transports in kasrt w ater were a-
chieved by attaching onto SS.Pond in karst conduit could permit and dilute the contamination, and it was the main site
to process the natural self-purification in karst w ater system.Water velocity was positive correlated with TSS,w hile
negative correlated w ith the ratio of bacteria attached on SS.The deposit at the entrance of the cave can capture and
slow release the bacterium,w hich leads to microbial contamination in karst water for a long period time.
Keywords: microbe;karst water;contamination;transport;attenuation
