Notes:
A. All concentrations are in ppm.

B. The Traverse Group sampled May 24, 2000. MDEQ sampled April 10-12, 2001.

C. Based on the most recent (2000) MDEQ criteria update.

D. The criterion defaults to the background value for Michigan soil, which is higher than the health-based criterion (MDNR 1991, 1993, MDEQ 2000).

E. Computed to protect surface water used as a drinking water source.

F. The GSIPC (derived from the GSI) was calculated assuming a typical hardness for surface water in the Northern Lower Peninsula of Michigan of 100 ppm (MDEQ 2000). The hardness of the surface water at the GTC50 property at the time of sampling was not reported.

G. The 18 ppm detections for bis(2-ethylhexyl)phthalate and carbazole were from a sample with an elevated limit of detection greater than the criterion. Therefore, the compound may be present at up to the limit of detection.

H. Using health effect information to calculate this criterion yields a result larger than 1,000,000,000 ppb or 1,000,000 ppm, that is, above 100%. The MDEQ reduces the value by default to 1,000,000,000 ppb, 1,000,000 ppm or 100% (MDEQ 2000). No real concentration can therefore exceed the criterion.

I. Both samples of mercury were detected at equal concentrations.
