The abandoned building on the American Synthetics property poses physical hazards to trespassers. There is no apparent health hazard due to chemical contamination in the soil on the property.


The building on the property should be repaired or replaced and the grounds landscaped to eliminate the physical hazards before the property is occupied again.

New environmental data or information concerning any proposed use of the property may require future health consultations.

The American Synthetics Health Consultation was prepared by the Michigan Department of Community Health under a cooperative agreement with the Agency for Toxic Substances and Disease Registry (ATSDR). It is in accordance with approved methodology and procedures existing at the time the health consultation was initiated.

1. A U.S. EPA contractor mentions "rumors of reported dumping into the sump well on the west side of the AS building" to justify a recommendation for groundwater sampling (Reference 1, p. 6-1).

2. On October 1, 1995, the environmental evaluation, regulatory, and enforcement functions of the Michigan Department of Natural Resources (MDNR) were transferred to the newly-formed Michigan Department of Environmental Quality (MDEQ).

3. There is no indication in the available documentation (References 1, 5, 6) that the U.S. EPA contractor, owner contractor, or MDEQ staff that investigated or cleaned up the property attempted to seal the window again. The window was open when MDCH staff visited the property during the MDEQ investigation in October 1996.

4. To accurately evaluate potential human exposure to chemicals in surface soil, ATSDR prefers surface soil samples to be no deeper than 6 inches.

5. Total population of complete census block groups which cover the majority of a 6-mile square centered on the site, without adjustment for areas within the groups beyond a 3 mile radius. The block group that includes the site covers most of the west half of that square, plus another 3-by-2 mile area adjacent to the northwest corner, extending more than 6 miles west-northwest of the site. Three block groups, the one including the site and two in Wayne County, meet at the northeast corner of the site.
