Abstract
Precipitation samples for measurement of stable-isotope ratios of hydrogen (a2H) and oxygen (a18O) were collected at the Norman Landfill Research Site in Norman, Oklahoma, from May 1996 to October 2008. Rainfall amounts also were measured at the site (U.S. Geological Survey gaging station 07229053) during the collection period. The a2H of precipitation samples ranged from .121.9 to +8.3 per mil, and the a18O of precipitation ranged from 16.96 to +0.50 per mil. The volume-weighted average values for a2H and a18O of precipitation over the 12-year measurement period were .31.13 per mil for a2H and .5.57 per mil for a18O. Average summer-season a2H and a18O values of precipitation usually were more positive (enriched in the heavier isotopes) than winter values.
