Abstract
Groundwater pollution by nitrate is an important environmental problem. Enhanced in-situ biodenitrification seems to be a clean and economical technology that allows remediating nitrate-polluted groundwater. Compound-specific isotope analysis (CSIA), on the other hand, is a powerful tool to determine the degree of nitrate degradation. Using the Rayleigh equation, it relates the change in the isotope ratio of the nitrate molecule (d 15 N - NO 3 -, d 18 O - NO 3 -) to the fraction of molecules rem...
