"The U.S. Environmental Protection Agency is planning to release its proposed Portland Harbor Superfund Site cleanup plan early next month.

The plan, 16 years in the making, will include the agency’s preferred option for cleaning up a 10-mile stretch of the Willamette River that’s highly contaminated from more than a century of industrial use. The EPA has spent years investigating the site and developing a range of options for reducing contamination to an “acceptable” level.

Cami Grandinetti, a project manager for the EPA, said a lot of information about what’s at the site is already available, including levels of contamination and human health and environmental risks."
