(WXYZ) — Officials with the Michigan Department of Environment, Great Lakes, and Energy have released partial test results from the Sanilac County and Detroit properties owned by Gary Sayers.
Sayers also owns the Madison Heights property that was home to Electro-Plating Services, the facility believed to be responsible for the green ooze that leaked onto I-696 late last year.
The Sanilac County tests have found no detectable levels of volatile organic compounds or heavy metals that exceed surface water quality criteria.The testing also did not find detectable levels of chemicals typically used in plating operations, like those conducted at Electro-Plating Services.
Soil samples did show the presence of silver, mercury, selenium and total chromium. However, these levels were below the levels that would raise concerns about public health. The results are still being analyzed.
Moving forward, EGLE says they will conduct a survey of the property using ground-penetrating radar to determine if drums or chemicals might have been dumped.
EGLE has also released testing results from Sayers property on Commonwealth in Detroit.
Results for the liquids found in concrete pits detected several heavy metals. However, they did not find hexavalent chromium or semi volatile organic compounds.
These liquids will still have to be deposed of, but officials with EGLE say they can be treated as non-hazardous waste.
Officials say once PFAS testing is completed next week, wastes from the pits will be vacuumed directly into a truck and hauled away for proper disposal.
