Dioxin
Below are listed the 17 compounds commonly referred to as Dioxin. Eleven of the compounds were not
detected (ND). Five were below the calibration range (J). (See page 52 of the lab report). The amount given
for these five is an estimate because it is below a measurable amount. In the initial lab analysis, it appeared
thatNumber 8, 2,3,7,8 -TCDF, was present. However when further analysis was done for that specific
analyte it was not detected (ND). (See page 78 of the lab report)

The compounds not detected (ND) are not present. Results which are below calibration range (J)
are statistically insignificant and have no toxic effects.
