Description

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 ... continued below

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).
