U.S. Environmental Protection Agency Region 5 has completed the first phase of soil sample collection from residential yards near the former Master Metals site in Detroit. The initial results from the samples are expected to be available by the end of this month.
From March 3 to 7, EPA collected about 70 soil samples to establish a "footprint" pattern of airborne lead-contamination. Sample points were based on computer modeling of the likely smokestack plumes from the former lead smelter. The smelter closed in 1983. Along with lead-content analysis, EPA is evaluating the samples for other heavy metals that may have been deposited in the area over the years.
EPA will consult with state and local agencies on the results of the Master Metals lead-soil sampling, including the Michigan Departments of Environmental Quality and Community Health, the Detroit Environmental Affairs and Health departments, and the Wayne County Department of Environment.
Separately, the final phase of cleanup at the former Master Metals facility is expected to begin early next month. EPA will oversee the work under the terms of a unilateral administrative order announced on February 6.
