former tank pad area free contaminant was also observed in the capillary fringe of the former tank pad area excessively contaminated soils extended from approximately 0 5 ft below ground to the capillary fringe the remediation system in this example included 35 bores a catalyst injection of 1 4 wt at 3 gpm followed by an oxidant injection of 25 wt at 1 3 gpm the results for six injection points ip are presented in table 1 at t 0 and t 1 1 week later measured quantities are given in units of micrograms per liter u03bcg l or parts per billion ppb bdl below detection limit red percent reduction btex benzene toluene ethyl benzene and xylene mtbe methyl tert butyl ether naph total naphthalenes the data in this table indicate that the process and system of the present invention are effective in significantly reducing contaminants to environmentally acceptable values such values may be determined by local regulations mandating such values as drinking water standards and soil cleanup goals the flexibility of the present invention makes it efficacious for reaching virtually any level desired measurements were also made throughout the remediation time from t 0 to 48 hours of temperature ph and conductivity and these are displayed in table 2 the data indicate that the site returns to approximately its pretreatment ph and temperature within 48 hours and the conductivity is reduced to 0 1 of the value measured upon introduction of catalyst solution table 1______________________________________process exemplary field study results ip1 t sub 0 ip1 t sub 1 red ip2 t sub 0 ip2 t sub 1 red______________________________________benzene 1900 260 86 3 11000 1800 83 6toluene 1100 180 83 6 1300 110.
