State water tests are coming back after a Detroit river shoreline collapsed at a polluted property that’s upstream from one of the Great Lakes Water Authority's drinking water intakes.
The property now used by Detroit Bulk Storage was used by a company that made uranium parts for bombs in the 1940s, and subsequently by other industries that polluted the soil.
On Friday, radiation levels on the property came back at lower than background levels. On Monday, a test for hydrocarbons came back non-detect. Results for other state tests at the site are still pending, for metals like arsenic and mercury, PCB's, and other contaminants. Those results are expected by the end of the week.
The water authority is doing similar tests downstream, at the water intake. The agency says those tests are highly specialized and will take about 3 to 6 weeks to complete.
