15 صفحه اولInvestigating surface water–well interaction using stable isotope ratios of water
Because surface water can be a source of undesirable water quality in a drinking water well, an understanding of the amount of surface water and its travel time to the well is needed to assess a well’s vulnerability. Stable isotope ratios of oxygen in river water at the City of La Crosse, Wisconsin, show peak-to-peak seasonal variation greater than 4‰ in 2001 and 2002. This seasonal signal was ...

15 صفحه اولThe effect of water velocity on stable carbon and nitrogen isotope signatures of periphyton
Water movement affects carbon and nitrogen isotopic signatures of algae, possibly through effects on boundarylayer thickness. We describe a laboratory experiment carried out in artificial streams, which supports this hypothesis. Periphyton d13C and d15N signatures were significantly depleted in 13C and 15N when grown at higher water velocity over the range of 5–62 cm s21, the normal range found...
