Notes:
A. All concentrations are in ppm.
B. TriMedia sampled November 9, 1999. MDEQ sampled May 15, 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. 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.

A. All concentrations are in ppb.
B. TriMedia sampled November 12, 1999. MDEQ sampled May 16, 2001.
C. Based on the most recent (2000) MDEQ criteria update.
D. 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.

Notes:
A. All concentrations are in ppm.
B. Based on the most recent (2000) MDEQ criteria update.
C. The criterion defaults to the background value for Michigan soil, which is higher than the health-based criteria (MDNR 1993, MDEQ 2000).
D. Using health effect information to calculate this criterion yields a result larger than 1,000,000,000 ppb, that is, above 100%. The MDEQ reduces the value by default to 1,000,000,000 ppb or 100% (MDEQ 2000). No real concentration can therefore exceed the DCC.
E. The maximum reported XRF iron concentration was 1,120,000 (± 65,000) ppm, that is, 112%., an unrealistic result. This sample also contained 350 ppm of lead, so a more realistic upper bound for the iron concentration, rounded to 3 significant figures, is 1,000,000 ppm. There were two other samples for which the raw XRF data indicated they contained 102 (± 5) and 101 (± 4) percent iron, with 2 and 3 percent total lead, manganese, and other metals, respectively (MDEQ 2001b).
