Giardia cysts and Cryptosporidium oocysts in water samples were detected simultaneouly using 1623 Method, which combined capsule/membrane filtration and immunomagnetic separation with immunofluorescence assay. In this study, raw water samples from 6 intakes, finished and tap water samples supplied from Kueui Water Treatment Plants in Seoul, and Wangsuk creek water samples were tested from April 1999 to February 2000, to estimate the prevalence of two protozoa in Seoul drinking water supplies. Giardia cysts were found in 25∼75% of water samples from 6 intakes in the range of 0∼9.7/10L. Cryptosporidium oocysts were found in 0∼50% of six intake water samples in the range of 0∼4/10L. Raw water samples from Kueui. Jayang, Pungnap intakes showed significantly higher concentration and more frequent incidence of Giardia than that from Paldang, Kangbuk. Amsa intakes. It seemed that Wangsuk creek acts as an important source of Giardia pollution in Kueui, Jayang. Pungnap intakes because all samples from Wangsuk creek, flowing in upstream of Kueui intakes, contained 19∼109/l0L of Giardia cysts. No Cryptosporidium and Giardia were found in all finished and tap water sample. We concluded that Giardia cysts are more often found in raw surface waters of Seoul than Cryptosporidium oocysts, although two protozoa were not detected in treated water samples of Kueui Water Treatment Plant.

The chromogenic enzyme substrate test(MMO-MUG) is a method based on technology that uses a hydrolyzable substrate as a specific indicator nutrient for the target microbes. This method is a simultaneously enumerate E. coli and total coliforms(TC) in drinking water without confirmatory test. Over a 6 months period(`99. 9.∼11. and `00. 6.∼8.), 2005 samples from drinking water distribution system were analyzed for TC, and E. coli by chromogenic enzyme substrate test(MMO-MUG), multiple tube fermentation(MTF) and membrane filtration(MF) method, using replicate 100mL sample volumes. The detection rate of TC by MMO-MUG, MTF and MF method were 1.4%, 1.4% and 1.1% respectively, The agreement ratio of MMO-MUG to MF and MMO-MUG to MTF were 99.3%(1991/2005) and 99.0%(1985/2005), respectively. The Overall agreement ratio was 98.6%. The comparison of the agreement ratios by nonparametric statistics demonstrated no significant difference. Species identifications from positive samples confirmed the sensitivity of the MMO-MUG(96%) So the MMO-MUG, MTF and MF used in this study, while not showing differences available in terms of overall consequence, made a few differences in terms of quickness, easiness and costs.

In order to compare the effect of water quality on two service systems, tank and direct connection service, we selected randomly 30 rooftop tanks installed in the buildings with five or fewer floors, and collected water samples from each tank as well as tap water by direct service. At the same time each tank was investigated on their cleanliness and sanitary control. 30 water samples from direct service met Korean Drinking water quality standard. But 5 tank water samples(17%) were not able to meet Coliform or Total Colony Counts standard and free chlorine of 12 tank water samples(40%) were less than 0.2㎎/L. Also Fe, Turbidity, TOC, Total Algae in tank water were higher than tap water on direct service. We concluded that thorough health control of water tank is necessary and conversion into direct connection service results in improving tap water quality importantly.
