Spike recoveries <br /> and the RPD' s for the method spikes were within acceptable limits . <br /> Spike recoveries for the matrix spikes could not be calculated because <br /> the presence of EDB exceeded the spike concentration and a diluted <br /> analysis was required. The method blank did not contain any target <br /> compounds or interfering peaks at or above the reporting limits Ini- <br /> tial and continuing calibration criteria were met for this analysis <br /> r <br /> • <br />
