Table 5. Organic carbon and nitrogen content (in percent) of the sediments and concentrations (mmol L-1) of DOC, NO3-, NH4+, and O2 in ground water from each site at the time of sample collection. [Dissolved organic carbon (DOC) is reported as mmol L-1 C; values reported as “0” were less than the detection limit.]
