Abstract
Although the detected amounts of those disease-causing(oo)cysts were high at each point in 2001, the detected amounts of Cryptosporidium and Giardia had decreased at low levels below 10(oo)cysts until 2004. Considered the detection results of each season, the most highly detected amounts of(oo)cysts were mostly recorded in summer and late summer(from June to September), while the site which the biggest amount was detected, was the point at Goryeung. The relation of Cryptosporidium with the water quality items was low, but the relations of Cryptosporidium and Giardia with turbidity were high($R^2$=0.4914, $R^2$=0.6176 respectively). And the detected amounts of Cryptosporidium and Giardia were relatively high, 20(oo)cysts/20L when the turbidity was more than 20 NTU. It was also found that the relation between the distribution of Cryptosporidium and Giardia was high, $R^2$=0.8432 and the density of Giardia was generally higher than that of Cryptosporidium. And Cryptosporidium and Giardia were simultaneously detected at each point. The primary sources that affected the density of those(oo)cysts were the livestock waste water and sewage.
