 Fractional NAPL Removal
 (FNR)

Figure 4-1. Sages 1998 ethanol flushing pilot test fractional NAPL removal to fractional
 flux reduction relationship.

 A favorable flux response to PCE removal was observed for most data points as they

were located to the left of the 1:1 line. The RW data shows that four or the six wells straddle the

1:1 relationship line. Brooks et al. [2003] documented this pattern at the Dover AFB site alcohol

flushing test, although four of six extraction wells exhibited less than 1:1 behavior, two recorded

slightly greater response. For the 1998 Sages flood, there were two RWs that plotted outside the

zero to one range of this figure. Both RW-5 and RW-7 produced concentration increases in this

test. In the MLS data, most of the depths indicated highly favorable flux reductions to a wide

range of fractional NAPL removals. Although there were several flux increases detected in the
