review, these instruments did not appear to reach true saturation (with a single exception) although these measurements were well beyond the linear range for quantitation as described above. Baseline or background measurements for each instrument were calculated by averaging the readings taken during the last full minute preceding the trial. Baseline values typically returned to within one standard deviation of this average within 17 minutes after the start of the trial. Plots of the chlorine concentration (ppm) over these 17 minutes for each instrument are shown in Appendix B. For Appendix B, plots labeled with red on the y-axis (concentration) denote a different scale (0 to 250,000 ppm) than those labeled in black (0 to 100,000 ppm). JazTM UV-Vis measurements in excess of 100,000 ppm were relatively infrequent across the five trials. Table 1: Overall Test Data Trial Date Tonnage/Lbs.

Instruments were placed within the mock urban layout as illustrated by Figure 1. More specific instrument locations including proximity to survey points are located in Appendix C. Figure 1. Instrument Layout for Trial 1 Quality control checks were performed on each instrument before and after the trial using a 10,000 ppm chlorine standard.

As part of Trial 2, twelve instruments successfully recorded the release. For this as well as subsequent trials, the internal instrument clocks were synchronized to within one second of the official DPG (JR2 control) test clock. Instruments 006 and 012 did not register a significant increase throughout the trial. Pre-trial and post-trial QC checks indicate both instruments were properly collecting data. The highest recorded chlorine concentration for any of the instruments was 95,509 ppm; therefore all measurements for this trial fell within the linear portion of the standard curve and can be considered quantitative. Four instruments (001, 007, 010 and 015) did not collect. Instruments 001, 007 and 015 failed due to a power loss after the pre trial QC check and before the release. As for Trial 1, crimping/recrimping the power leads fixed this problem, Instrument 010 had a light source failure. The light source was replaced and the instrument recalibrated prior to Trial 3.
