Urban Stormwater Tracing with the Naturally Occurring Deuterium Isotope
Measurements of naturally occurring deuterium isotope (δD) assist in tracing water components during wet weather flows in an urban watershed. A transect of installations in the vadose and saturated zones was completed in the vicinity of a small stream and storm sewer. High‐resolution deuterium mass spectrometry discriminated between storm sewer leaks and other water sources such as direct runoff, bank seepage, and groundwater flow to a stream channel. Isotope hydrograph separation indicates that groundwater or vadose water predominantly contributed to the volume of stream water compared to direct surface runoff during a storm event. Significant differences in δD in the subsurface suggest that multiple flow components exist beyond the time period of a storm event. Deuterium measurements are helpful for modeling leaks and seepage and refining mass balances of flows in urban watersheds.
