PY - 1981// TI - Gaseous nitrogen as evidence for denitrification in groundwater JO - Journal of Hydrology SP - 191 EP - 200 VL - 50 N2 - By investigating the nitrate, oxygen, nitrogen and argon concentrations and 15N14N ratios in artesian groundwater with radiocarbon ages ranging up to 27,000 yr. a process of very slow denitrification in a confined aquifer is demonstrated. The calculated nitrogenisotope fractionation factor associated with this reaction is comparable to that reported for bacterial cultures in vitro and in vivo.
