“…Empirical models, such as the Monod equation (Monod 1949;Simkins and Alexander 1984), are standard tools for describing rates of microbial metabolism in laboratory and industrial settings, as well as in natural systems. However, direct application of these models to natural environments has not always been successful, as predictions by empirical models can deviate by orders of magnitude from field observations (Brown et al 2000;Chapelle and Lovley 1990;Murphy and Schramke 1998;Reeburgh 1983).…”

“…Interestingly, the enrichments of dissolved Fe and Mn are observed in many samples from the upper aquifer ( Figure 6). It is noticeable because high concentrations of dissolved Fe or Mn frequently create a problem in the use of RBF technology [62,63]. Many groundwater samples from the upper aquifer are significantly lower in DO values than river water and pond water, approaching sub-oxic conditions (DO < 4 mg/L).…”

“…Pore water analyzed for dissolved iron was acidified immediately after extraction. Some ferrous iron in pore water may have been oxidized during pore-water extraction, however, because anaerobic conditions are difficult to maintain during extraction; further discussion is given in Brown, Schoonen, and Candela (2000). Moisture content of the sediments was measured by oven drying (to 110° C) a separate subsample of the same material; the resulting values were used to calculate the extent of pore-water dilution by deionized water.…”
