Concentrations of O2, methane, and CO2, are not typical of a mature gas producing landfill, as O2 concentrations should be less than 2 percent, methane greater than 50 percent, and CO2 greater than 35 percent. In response to these questionable results, additional landfill gas measurements were taken during the October 2007 field campaign. These results are presented in Section 3.3 of this document. The results shown in Table 3-35 appear to be the most valid results for methane and CO2. 3.2.5 Total Mercury Measurements Total mercury concentrations in the landfill gas at Site #2 ranged from 36 to 47 ng/m 3 , with an average of 43 ng/m 3 for all of the samples. Spike recoveries for the total mercury samples were 89.9 and 97.6 percent. Table 3-36 presents the total mercury concentration data from Site #2. 3-36
