This study was designed to investigate the quality of the simplified water supplies by regional groups in Uijoungbu. For this objective physicochemistric and microbiological experiment were performed. Simplified water in Uijoungbu(Howondong Darakwon, Singokdong Chudong, Songsandong Mangadae, Songsandong Gacbawe, Songsandong Gusungmal, Songsandong Baebul, Ganeung3dong) tested by this study physicochemistric elements suited the test. However, Songsandong Mangadae exceeded the minimum level suggested as $NO_3-N(10mg/{\ell})$. The population of general bacteria were exceeded the minimum level suggested as drinkable water(less than $100CFU/m{\ell}$). Some simplified water in Uijoungbu were proven to be contaminated.
