Abstract
The nitrogen concentration in groundwater and stream water exceeds environmental standards at some location in the southern region of the Miura Peninsula. In this region, the influence of fertilizer and domestic wastewater is indicated as a cause of the groundwater and stream water contamination.<BR>In this study, to clarify the influence of domestic wastewater, the contribution rate of tap water to river water was calculated using stable oxygen isotopes.<BR>In stream water and tap water in Miura City, a difference was seen in the stable isotope ratio of oxygen because of a difference in mean elevation of the watersheds. The domestic wastewater contribution rate calculated from stable oxygen isotopes in deep groundwater and tap water ranged from 6 to 30 %.
