This poster provides a one-page summary of research to quantify actual denitrification in groundwater systems.
Measurement of neon, argon and N2(g) identifies:
1. Excess N2(g) from denitrification of nitrates
2. In future, N2(g) can be determined using isotopes to
analyse N origin (air or nitrates)
3. Combined tracer techniques are complimentary
