Hi Jessica
The following published gas evolution techniques have been used to
analyze for DIC in landfill leachates and groundwater
Games, L. M. and Hayes, J. M., 1976. Isolation and quantitative analysis
of the major carbon fractions in natural water samples. Anal. Chem. 48,
130-135.
Atekwana EA, Krishnamurthy RV. 1998. Investigations of seasonal
variations in dissolved inorganic carbon and d13C of surface waters
using a modified gas evolution technique. Journal of Hydrology 205:
265-278.
Some additional references on DIC in landfills include:

landfill leachate in groundwater. J. Water Pollution Control Federation
49: 668-677.

Thanks Ethan - I look forward to receiving the papers.
Just a quick question: did you analyse for d13C-DIC? If so, what method
did you use? I've been trying precipitation with barium chloride with
little success.
Regards,
Jessica

I'll send a couple of related papers.
