c <br /> Monitoring during the initial addition of nutrients will be <br /> performed daily to every other day until the breakthrough of <br /> tracers is detected in the recovery well (s). After that , <br /> 3 <br /> monitoring will be performed three times a week until <br /> concentrations of the nutrients at the recovery well (s) have <br /> t stabilized. The exterior wells will also be monitored on the <br /> same schedule to assure us that nutrients do not reach that area. <br /> j <br /> i <br /> H;ldrogen peroxide addition will begin later. The same monitoring <br /> strategy used during nutrient addition will be used for peroxide. <br /> In both cases, the Total Hydrocarbon Degraders (THC) and Total <br /> Aarobic Bacteria (CFU) will be determined on `weekly basis. <br /> ROUTINE <br /> Groundwater from`i elected, welI's' will be sampled semi-weekly to <br /> monthly to evaluat°\ )W progress of the remediation <br /> .(Tabie 7), <br /> : Dissolved oxygen, pH, Eh, conductivity, and temperature will be k <br /> measured. by probes. <br /> t Wet chemical analyses .will .be performed. for ammonium, phosphate <br /> k <br /> k chloride, and, as necessary, nitrate.
