WENATCHEE — With 25 tons of arsenic-contaminated rock and soil, an articulating dump truck slowly moves down the lower end of Saddle Rock an average of 25 times a day. The truck can swivel in front of its load, able to make the sharp corners of the dirt road down the mountain.
The months-long project to remove four dump sites used by miners from the 1930s to 1950s started in mid September and should wrap up in November, according to Charlotte Mitchell, capital projects manager with the city of Wenatchee. The timing depends mainly on the weather. It gets pretty slick on the hillside where they are working when it rains, she said.
