Flood raises fears of pollution at Michigan toxic waste site

TRAVERSE CITY, Mich. (AP) — It took seven years to settle on a plan for cleansing two rivers and floodplains polluted with dioxins from a Dow Chemical Co. plant in central Michigan. The work itself has lasted nearly twice as long, with plenty still to do.

Now, scientists and activists fear some of the progress may have washed away with floodwaters that overwhelmed two dams this week, chasing 11,000 people from homes in and near Midland, the company's headquarters city.

The Tittabawassee River flows past the Dow plant and eventually meets the Saginaw River, which continues into Lake Huron's Saginaw Bay. That 50-mile stretch is tainted with dioxins — highly toxic compounds that researchers say can damage reproductive and immune systems and cause cancer. The area is on the federal Superfund list of hazardous sites.

Regulators and company officials said Thursday it was too early to tell whether the swollen river had damaged spots that had been repaired or swept pollutants farther downstream. Dow said it would inspect each cleanup location as floodwaters recede and sample for new contamination.

The projects “held up remarkably well” during a 2017 flood “and we are confident that we will see a similar outcome this time," spokesman Kyle Bandlow said.

The U.S. Environmental Protection Agency said it would team with the Michigan Department of Environment, Great Lakes and Energy to evaluate any chemical releases from the plant, although Dow had reported none. Damage from the flood three years ago was “minimal” and required only minor repairs, EPA's regional office in Chicago said.

But a similar outcome is unlikely after this week's considerably bigger flood, said Allen Burton, a professor of environment and sustainability at the University of Michigan.
