In Kellogg, Idaho, the construction season is wrapping up on a big project whose goal is to greatly reduce the amount of pollution that makes its way into the south fork of the Coeur d’Alene River.
Rod Zion is overseeing the project for the U.S. Army Corps of Engineers.
He says it has three parts. First, crews are adding capacity to that huge earthen berm you see from Interstate 90 as you drive near Kellogg. Second, they’re building an underground wall that will run along the freeway. And third, they’re adding new technology a water treatment plant that’s 45 years old and way overdue for an update.
