Dual measurement of 13C and 14 isotopic composition to identify
Samples of groundwater were collected in the spring of 1996 for *jC and 14C determinations of dissolved inorganic carbon (DIC). A sample of the FHC collected during steam injection was also analyzed. Groundwater was collected after appropriate pumping times in I-CHEM l25ml amber glass bottles fitted with l/8 inch teflon-coated rubber septa inserted into threaded caps. Bottles were filled leaving approximately a two inch head space, treated with 4 drops of saturated HgC12 solution, and stored upside- down refrigerated until analyses. Analyses were performed within 48 hours of collection. Two duplicates were collected using evacuated glass cylinders equipped with greased stopcocks and a l/4 inch rubber septa plug. Results of these duplicate samples were identical to those collected in the septa bottles (see Table 1).
