"Dam Failure Threatens a Dow Chemical Complex and Superfund Cleanup"

"Floodwaters from two breached dams in Michigan on Wednesday flowed into a sprawling Dow chemical complex and threatened a vast Superfund toxic-cleanup site downriver, raising concerns of wider environmental fallout from the dam disaster and historic flooding.

The compound, which also houses the chemical giant’s world headquarters, lies on the banks of the Tittabawassee River in Midland, where by late Wednesday rising water had encroached on some parts of downtown. Kyle Bandlow, a Dow spokesman, said that floodwaters had reached the Dow site’s outer boundaries and had flowed into retaining ponds designed to hold what he described as brine water used on the site.

The Superfund cleanup sites are downriver from the century-old plant, which for decades had released chemicals into the nearby waterways. The concern downriver, according to Allen Burton, a professor of earth and environmental sciences at the University of Michigan, is that contaminated sediments on the river floor could be stirred up by the floodwaters, spreading pollution downstream and over the riverbanks."
